[Used] Amp VT Tube Amplifier

Ich habe den etwa baugleichen Amp von Madison mit 2x25W. Gedacht fürs Schlafzimmer.Es gibt einige "Marken" die sich die gleiche Konstruktion teilen.Um es klarzustellen: es ist ein HYBRID-Röhrenverstärker, Röhren im Preamp-Modus, Leistungsverstärkung von Transistor-Endstufe. Also kein reiner Röhrenverstärker.Der Kasten dahinter ist aus dem Grund leer dass dessen Inhalt in die Basis gewandert ist.Der Klang ist top, besser als an meinem Cambridge Audio Azur. Weich, seidig, mehr Details und ein Schuss Wärme. Bass ist insgesamt kräftiger. Für meine Klipsch RP600 mit 96db Wirkungsgrad sind 25W mehr als genug.. Ab einer viertel Drehung wirds schon sehr laut.Zukünftig kommen ein paar Wharfedale Diamond 220 dran, die Klipsch sind nur zum testen.Selbst mit den hellen, hochtonlastigeren Klipsch ist das Klangbild viel runder und angenehmer, zum stundenlangen Hören besser geeignet als am Cambridge.Für das Geld ist der Klang wirklich überraschend und überragend gut!Es ist wohl auch möglich die verbauten (chinesischen) Röhren gegen hochwertigere (russische) auszutauschen und den Klang zu pimpen.

I have a roughly identical 2x25W Madison amp. It's intended for the bedroom. There are several "brands" that share the same design. To be clear: it's a hybrid tube amplifier, tubes in the preamp mode, with power amplification from a solid-state power amp. So, it's not a pure tube amplifier. The cabinet behind it is empty because its contents have been moved into the base. The sound is excellent, better than my Cambridge Audio Azur. Smooth, silky, with more detail and a touch of warmth. The bass is overall more powerful. For my Klipsch RP600 with 96dB efficiency, 25W is more than enough. It gets very loud at a quarter turn. I'll be adding a pair of Wharfedale Diamond 220s in the future; the Klipsch ones are just for testing. Even with the brighter, more treble-heavy Klipsch speakers, the sound is much rounder and more pleasant, better suited for hours of listening than the Cambridge. For the money, the sound is truly surprising and outstandingly good! It's also possible to replace the installed (Chinese) tubes with higher-quality (Russian) ones and improve the sound.

Llegó perfectamente. Muchas gracias.

It arrived perfectly. Thank you very much.

amante dell'hi-fi ma senza spendere cifre esorbitanti, ho acquistato questo amplificatore piu' per curiosita' che altro.Devo dire, che la differenza acustica dai classici amplificatori che si trovano in commercio si fa sentire. il suono risulta piu' caldo corposo e sopratutto i bassi risultano pieni e profondi. a livello audio, per i miei gusti avrei preferito una risposta maggiore sulle frequenze acute, ma nel complesso e' gradevole.confermo i difetti riscontrati, che la manopola del volume fino a un po' meno di meta'aumenta di poco il suono, da li fino a tre/quarti si ha la massima escursione del volume, poi nell'ultimo quarto, sembra non aumentare piu'. Ho colorato di bianco la tacchetta delle manopole, perche' sennò non si riesce mai a vedere la posizione della stessa. altro difetto ma non inficia sulla qualita' sonora, e' il vu-meter che ai bassi volumi, quasi non si muove. collego tramite il bluetooth sia un piatto che una radio dab che un lettore mp3. funziona tutto stupendamente senza rumori alcuni.non ultimo la bellezza dell'oggetto che fa sicuramente scena.

A lover of hi-fi but without spending exorbitant amounts, I bought this amplifier more out of curiosity than anything else. I must say, that the acoustic difference from the classic amplifiers found on the market is noticeable. The sound is warmer and fuller, and especially the bass is full and deep. In terms of audio, for my tastes I would have preferred a greater response on the high frequencies, but overall it is pleasant. I confirm the defects found, that the volume knob up to a little less than halfway increases the sound slightly, from there up to three-quarters you have the maximum volume excursion, then in the last quarter, it seems not to increase anymore. I colored the knobs white, because otherwise you can never see their position. Another defect, but it does not affect the sound quality, is the VU-meter which at low volumes almost does not move. I connect via Bluetooth both a turntable, a DAB radio and an MP3 player. Everything works beautifully without any noise. Not least the beauty of the object which certainly makes a scene.

Consigliatissimo

Highly recommended

Sehr gut verpackt. Leicht aufzubauen.Der Ton ist wirklich ausgesprochen agenehm. Ich höre hauptsächlich Jazz, Folk und Klassik damit.Auch die Optik ist toll. Also um das Geld kann ich wirklich nicht meckern.

Very well packaged. Easy to set up. The sound is truly exceptionally pleasant. I mainly listen to jazz, folk, and classical music with it. The look is also great. So, for the money, I really can't complain.

Sieht gut aus.

Looks good.

Ottimo venditore,veloce. Ottimo imballo. Amplificatore fatto veramente bene. Sono molto contento. Consiglio a tutti.

Great seller, fast. Excellent packaging. Really well-made amplifier. I'm very happy. I recommend it to everyone.

Lo compré para sustituir una micro cadena estropeada, manteniendo los altavoces Philips de la cadena. El amplificador tiene un previo de válvulas que aporta una calidez al sonido, con un selector de entradas bluetooth-usb, auxiliar por RCA y digital tanto en coaxial como óptica. Echo de menos alguna entrada más analógica. La parte de amplificación se comporta de forma correcta, entregando unos 20 - 25W RMS por canal (anuncia 35W pero seguramente a 4 homios). Otra pega que veo es que el potenciómetro es lineal y funciona de forma efectiva en un rango del 30 al 70%. Por debajo del 30% no tiene prácticamente volumen y por encimadel 70% no aumenta el volumen. El bluetooth tiene un alcance adecuado y la entrada USB frontal, solo reproduce MP3, no reproduce formato FLAC. Dispone de un botón para pasar canciones hacia delante y hacia atrás. Como no puede manejar carpetas, unidades de memoria USB grandes con muchas canciones, son complicadas de gestionar. Yo he recuperado memorias antiguas de 1gb. Aunque se nota que la construcción no es igual que un equipo Sony o Pioner, pero por ahora parece que funciona bien. La estética del amplificador es preciosa, con iluminación ámbar, aunque el VU-Meter solo se mueve algo a muy altos volumenes.Estos pequeños inconvenientes se compensan por la calidad del sonido que entrega. Lo uso principalmente con un viejo ipod lleno de música y con un reproductor mp3-FLAC Hi Res.Por ahora estoy muy contento sobre todo porque lo conseguí en el black friday a un precio muy bueno. Equipo totalmente recomendado (por ahora, a ver si dura mucho tiempo)

I bought it to replace a broken micro system, keeping the Philips speakers in the system. The amplifier has a tube preamp that adds warmth to the sound, with a Bluetooth-USB input selector, auxiliary RCA input, and digital coaxial and optical inputs. I miss a more analog input. The amplification part behaves correctly, delivering about 20-25W RMS per channel (it advertises 35W, but probably at 4 ohms). Another drawback I see is that the potentiometer is linear and works effectively in a range of 30-70%. Below 30%, there is practically no volume, and above 70%, the volume doesn't increase. The Bluetooth has a decent range, and the front USB input only plays MP3s; it doesn't play FLAC. It has a button to skip songs forward and backward. Since it can't handle folders, large USB flash drives with many songs are difficult to manage. I've recovered old 1GB flash drives. Although it's noticeable that the build isn't the same as Sony or Pioneer equipment, for now it seems to be working well. The amp's aesthetic is beautiful, with amber lighting, although the VU meter only fluctuates slightly at very high volumes. These minor drawbacks are offset by the sound quality it delivers. I mainly use it with an old iPod full of music and a Hi-Res MP3-FLAC player. So far, I'm very happy, especially because I got it on Black Friday at a very good price. I highly recommend it (for now, let's see if it lasts a long time).

Ampli de rapport qualité prix correct.Sympa si on veux découvrir les amplis à tubes. Les éclairages leds bleus pour simuler le fonctionnement de certains "vrais" ampli à lampes c’est un peu kitch mais bon...

Amp with a good price-quality ratio. Nice if you want to discover tube amps. The blue LED lighting to simulate the operation of certain "real" tube amps is a bit kitsch, but hey...

  Arrivato oggi lo sto testando ,devo dire che ha un bel suono caldo, per Quei pochi centinaio di euro non si può pretendere la gamma top, ma suona molto bene bello e pulito, lo smider si muove bene, il Bluetooth funziona benissimo la USB va benissimo, ma continuerò a testarlo, premesso ho delle casse marca napolima nonostante suona bello caldo pieno. Lo consiglio a chi non ha pretese eccessive.Complimenti ad AUNA, sono riusciti a creare un prodotto ottimo senza troppe pretese.Suona bene suono caldo, l' ho testato con fonte aux con phono con bluetooth, e devo dire che si comporta davvero bene, se poi si vuole di più allora bisogna salire di prezzo in maniera impegnativa. Non devo fare la discoteca in casa, ho anche un ampli Philips di un impianto vintage, ma questo suona decisamente meglio.non si può pretendere di più per meno di 150 € , bene bravi gli ingegneri AUNA.

Unable to load media. I'm testing it. It arrived today and I have to say that it has a nice warm sound. For those few hundred euros you can't expect top-of-the-range, but it sounds very good, nice and clean. The speaker moves well, Bluetooth works very well, the USB is fine, but I will continue to test it. I have some Napoli brand speakers, although it sounds nice and warm and full. I recommend it to those who don't have excessive expectations. Congratulations to AUNA, they managed to create an excellent product without too many expectations. It sounds good, warm sound. I tested it with an aux source with a phono input and Bluetooth, and I have to say that it performs really well. If you want more, then you have to go up the price significantly. I don't have to set up a disco at home. I also have a Philips amplifier from a vintage system, but this one sounds definitely better. You can't expect more for less than €150. Well done to the AUNA engineers.

Wer sich mit dem Gedanken quält eine Röhre zu kaufen oder nicht, der sollte hier für 101Euro sofort zuschlagen. Zum Kennenlernen perfekt. Wenn du das Ding auspackst bist du verliebt. Erstklassige Verarbeitung, spielt bis gehobene Zimmerlautstärke mit einem Schmelz, unglaublich.

Anyone torturing themselves over whether or not to buy a tube should jump at this one for €101. It's perfect for getting to know it. You'll fall in love as soon as you unpack it. First-class workmanship, it plays with incredible smoothness even at room volumes.

Top Klang. Nur eine Fernbedienung ist nicht vorhanden.

Great sound. The only thing missing is a remote control.

Un son clair et précis .Manque un peu de Bass et donc de profondeurMais le son est plus que correctJe le conseille pour un budget serré.

A clear and precise sound. Lacks a little bass and therefore depth. But the sound is more than adequate. I recommend it for a tight budget.

Ein Herrlicher Fake.Es ist doch ein Transistor Verstärker. ( äquivalet Bd243/244 ) Nichts Röhre - Deswegen Fake.Läuft sehr gut. Die Lausprecher werden erst freigeschaltet wenn die Röhren aufgeheizt sind, kein Plop.Ich werde ihm noch 50 Hz Brumm verpassen ( 2 x 1 Megaohm Widerstände ) an den Eingang vor Gleichrichter abgenommen, damit das Ding einen leichten 50 Hz Brumm bekommt, dann ist der Röhrensound perfekt, Also doch ein Bausatz . Übrigens ,der Schwarze Kasten ist leer.Das Gewicht kommt vom Ring- Kern- Trafo.Aber macht Spass . Ich gebe das Ding nicht mehr her.Ich habe mir noch einen zweiten besorgt, dieser ist am Subwoofer Ausgang des ersten angeschlossen,Dieser Klang ist unbeschreiblich GUT. Der Hammer !!Heba2909.

A wonderful fake. It's a transistor amplifier (equivalent to Bd243/244). Nothing tube - that's why it's fake. Works very well. The speakers are only activated when the tubes have heated up, no pop. I'm going to give it a 50 Hz hum (2 x 1 Megaohm resistors) at the input before the rectifier so that the thing gets a slight 50 Hz hum, then the tube sound will be perfect, so it's a kit after all. By the way, the black box is empty. The weight comes from the toroidal core transformer. But it's fun. I'm not giving this thing away anymore. I've got myself a second one, this one is connected to the subwoofer output of the first one. The sound is indescribably GOOD. Awesome!! Heba2909.

Non mi reputo un grande esperto di hi-fi ma appena collegato ho subito notato la differenza con l'altro ampli un Denon da 50wattRms entry level di 20 anni fa, bassi si sentono molto ma molto meglio, netta differenza. Ho delle casse da 8 ohm per cui l'ampli lavora al massimo volume, ma non distorce, anche perchè è dato 25 Wrms su 4 ohmi per cui assorbirà circa la metà.Che dire a questo prezzo un amplificatore ibrido non esiste, per una cifra "irrosoria" ci si porta a casa un buon amplificatore.Manca il bilanciamento dx-sx e un tasto per by-passare tutti i controlli, sono piccole chicche però sarebbero state apprezzate.Non aspettatevi grandi rifiniture, amplificatore stra consigliato

I don't consider myself a great hi-fi expert, but as soon as I connected it I immediately noticed the difference with the other amplifier, a 20-year-old entry-level 50-watt RMS Denon. The bass is much, much better, a clear difference. I have 8-ohm speakers, so the amp works at maximum volume, but it doesn't distort, also because it's rated at 25 W RMS into 4 ohms, so it will draw about half as much. What can I say? At this price, a hybrid amplifier doesn't exist. For a "negligible" sum, you can get a good amplifier. It lacks left-right balance and a button to bypass all the controls. These are small touches, but they would have been appreciated. Don't expect great finishes. I highly recommend this amplifier.

Très bon ampli a tube très puissant et connexion optique vraiment très pratique

Very good tube amp, very powerful and optical connection really very practical

Superbe ampli a tube fonctionnement très bien connection optique très pratique.

Superb tube amp, works very well, very practical optical connection.

Positives: - klingt überraschend gut für den Preis (deutlich besser als z. B. Fosi Audio BT20A) - sieht schick aus - ausgewogener Klang Negatives: - (VERMUTUNG) Lautstärkeregler scheint nicht logarithmisch sondern linear zu sein. Zwischen halber und voller Lautstärke gibt es kaum merkbaren Lautstärkezuwachs. - Bei ganz leisen Lautstärken gibt es Lautstärkeunterschiede zwischen beiden Kanälen. Bei mir kommt beim Aufrehen von null erst der linke, dann der rechte Kanal. - Mein Exemplar kam, anders als in der Bedienungsanleitung angegeben mit 6U1-Röhren statt der 6P1 (musste ich leidig feststellen, weil eine meiner Röhren bei Lieferung defekt war (Aufschrift bei den gelieferten Röhren war nicht wirklich lesbar) und die nachbestellten 6P1 nichts außer massives Brummen verursacht haben. Erst Nachmessen der noch intakten Röhre haben mich auf den richtigen Pfad gebracht) - Schwacher Bluetooth-Empfang Optimierungsbedarf: - Externer Anschluss einer Bluetooth-Antenne wünschenswert (hätte das Gerät am liebsten mal geöffnet um zu gucken ob der Anschluss einer ext. Antenne möglich ist, will aber nicht auf die Garantie verzichten). Beurteilung: Unabhängig der abweichenden Pin- und somit Röhrenbelegung und des sicherlich dem niedrigen Preis geschuldeten, nicht sonderlich hochwertigen, Lautstärke-Potentiometers klingt dieser Verstärker überraschend gut. Dieser ersetzt den zuvor genutzten Fosi Audio BT20A und schlägt diesen im Sound um weiten (BT20A hatte eine starke Mittenüberhöhung und erinnerte mich klanglich irgendwie an eine Pringles-Packung. Merkwürdiger, aber treffender Vergleich. Glaubt mir...). Auch die räumliche Abbildung ist im (subjektiven) Vergleich Vorgänger um längen besser. Auch (absichtlich) übersteuerte Bässe (Youtube: Pharmacist - North Memphis) werden deutlich sauberer und somit angenehmer wiedergegeben - klingen nicht nach Backblech wie eim vorhergehenden Class D-Fosi (bestellt euch beide Amps, vergleicht selbst und gebt mir recht!). Vergesst bitte nicht, dass dies hier nicht der Circlotron vom Gerhard Haas ist (habe ein selbst zusammengebautes Exemplar im Audio-Raum stehen. Teile-Kosten allein für zwei Endstufen: locker 3500 € - Ohne Platinen, Kabel, Gehäuse, Vorverstärker), aber für läppische 135 € ist dieser Amp (steht bei mir im Wohnzimmer unterm TV - Damit die Kids die großen Kaliber nicht kaputt machen) seinen Preis allemal mehr als Wert. Wer sollte sich dieses Gerät kaufen? - Jeder der auf die Vorzüge von Röhren (sanfte, gerade Obertöne) und schönem Klang außerhalb des Haupt-Musikzimmers halbwegs wert legt, ohne groß in die Tasche greifen zu wollen - Jeder der lieber Musik hört als heizt (Röhren werden handwarm - Nordstream 2 wird ja boykottiert und Nordstream 1 hat kaum Durchsatz) - Perfekt als Geschenkideen für Neffe/Nichte/eigene Kinder Ah, fast vergessen: Das Beste in meinen Augen ist, dass wenn der Verstärker zuvor via Bluetooth mit z.B. einem Tablet verbunden war die Musikwiedergabe automatisch startet, sobald der Verstärker wieder eingeschaltet wird. Ich habe ein dediziertes Gerät zum Streamen und diese Funktion erspart es mir jedes Mal das Tablet zur Hand zu nehmen um die Wiedergabe zu starten (Die Wiedergabe kann übrigens vom Gerät ausgesteurt werden. Also Prev/Next sowie Play/Pause). Grüßle aus Mittelfranken

Positives: - sounds surprisingly good for the price (much better than e.g. Fosi Audio BT20A) - looks smart - balanced sound Negatives: - (GUESS) Volume control doesn't seem to be logarithmic but linear. There is hardly any noticeable increase in volume between halfway and full volume. - At very low volumes, there are volume differences between the two channels. When I turn up from zero, the left channel comes first, then the right channel. - My copy came, contrary to what is stated in the operating instructions, with 6U1 tubes instead of the 6P1 (I had to find out with regret because one of my tubes was defective when it was delivered (the label on the tubes delivered was not really legible) and the 6P1s I ordered were nothing but solid have caused hum. It was only after measuring the still intact tube that I got on the right path) - Weak Bluetooth reception Need for optimization: - External connection of a Bluetooth antenna desirable (would have liked to open the device to see if the connection of an ext. antenna is possible, but does not want to give up the guarantee). Assessment: Regardless of the different pin and tube assignments and the volume potentiometer, which is certainly due to the low price and not particularly high quality, this amplifier sounds surprisingly good. This replaces the previously used Fosi Audio BT20A and beats it by far in terms of sound (BT20A had a strong midrange increase and somehow reminded me of a Pringles pack. Strange, but apt comparison. Believe me...). The spatial imaging is also far better in a (subjective) comparison to the predecessor. Even (intentionally) overdriven basses (Youtube: Pharmacist - North Memphis) are reproduced much cleaner and therefore more pleasant - don't sound like a baking sheet like the previous Class D-Fosi (order both amps, compare them yourself and agree with me!). Please don't forget that this is not Gerhard Haas' Circlotron (I have a self-assembled copy in the audio room. Parts costs alone for two power amplifiers: easily €3500 - without circuit boards, cables, housing, preamplifier), but for For a paltry €135, this amp (it's in my living room under the TV - so the kids don't break the big calibres) is more than worth its price. Who should buy this device? - Anyone who values the benefits of tubes (smooth, straight overtones) and nice sound outside of the main music room without wanting to dig deep into their pockets - Anyone who would rather listen to music than heat (tubes get lukewarm - Nord Stream 2 will yes boycotted and Nord Stream 1 has hardly any throughput) - Perfect as a gift idea for nephew/niece/own children Ah, almost forgot: The best thing in my opinion is that if the amplifier was previously connected via Bluetooth to a tablet, for example, the music playback starts automatically, as soon as the amplifier is switched on again. I have a dedicated device for streaming and this feature saves me from having to pick up my tablet every time to start playback (By the way, playback can be controlled from the device. So prev/next and play/pause). Greetings from Middle Franconia

She looks amazing and sound is clear and exact I wonderer what its usb connection make. It dont work at all (not play music any memorystick although it has adjustment noddle) I play music only bt connection so it doesn`t matter Only minus in my device that VU meter doesn`t work. When compares its cheap price device is good purchase. Minimalism rules.

Ich finde den Verstärker für den Preis sehr gut. Der Klang ist super, nur die Reichweite der Bluetoothverbindung könnte besser sein.

I think the amp is very good for the price. The sound is great, only the range of the Bluetooth connection could be better.

Ich habe das Gerät heute erhalten und hatte ein gemischtes Gefühl, weil ein Rezensent von Verzerrungen gesprochen hatte. Der Ton ist brillant und klar, das Gerät ein Hingucker! Ich bin begeistert!

I received the device today and had mixed feelings because a reviewer mentioned distortion. The sound is brilliant and clear, the device is an eye-catcher! I'm excited!

bardzo ladne urzadzenie szkoda ze jedno jedyne urzadzenie pasujace do wzmaczniacza jest CD kture ma te same wymiary kolor nie koniecznie

very nice device, it's a pity that the only device that matches the amplifier is a CD that has the same dimensions, the color is not necessarily

alles gut

everything's ok

Ich wollte immer schon einen Röhrenverstärker besitzen, war aber nicht bereit, die Summe zu bezahlen, die ein seriöses Gerät kostet. So ließ ich mich durch die überwiegend positiven Besprechungen hinreißen, dieses Gerät zu kaufen, wohl wissend, dass sich ein guter Vollverstärker für 100.- nicht ausgehen kann, schon gar nicht mit Röhren. Der Vergleich mit einem hochwertigen Transistorgerät war ev. nicht fair, aber Wunder habe ich mir ohnedies nicht erwartet, aber die Verzerrungen vor allem der Stimmen war jedenfalls für meine Ohren nicht tolerabel. Vermutlich ist das Gerät besser aufgehoben mit kleinen Boxen an Computern und Ähnlichem. Dafür und auch dafür, was das Ding optisch hermacht fürs Geld, gebe ich dann doch drei Sterne. Aber meines geht retour.

I've always wanted to own a tube amp, but wasn't willing to pay the sum that a serious unit costs. So I allowed myself to be carried away by the predominantly positive reviews into buying this device, knowing full well that a good integrated amplifier can't go for 100.00, especially not with tubes. The comparison with a high-quality transistor device might not have been fair, but I didn't expect miracles anyway, but the distortion, especially of the voices, was intolerable for my ears. The device is probably better off with small boxes on computers and the like. For that and also for what the thing looks good for the money, I give it three stars. But mine is going back.
