AIYIMA T8 6N3 Digital Tube voorversterker QCC3031 Bluetooth 5.0 voorversterker USB DAC hoofdtelefoonversterker coaxiale optische stereo audio decode ondersteuning APTX

Een goed gebouwde Chinees met een uistekende prijs/kwaliteit verhouding. De geluidskwaliteit is uitstekend. Ik gebruik hem als hoofdtelefoon versterker voor de pc en cdspeler. Ook Bluetooth is prima. Voor de zelfde kwaliteit betaal je bij de grote namen zeker 4 keer zoveel. Is gekocht als simpele vervanger van een dac....overtreft alle verwachtingen. De stereo installatie heeft nu zware concurrentie

perfect for adding a remote controll. to otherwiste remoteless vintage hifi. it has a nice warm sound

Rettifico completamente la precedente recensione. l'amplificatore non è difettoso, il problema era generato da un malfunzionamento del trasmettitore che trasmetteva il canale sinistro su entrambi i canali. Di conseguenza l'oggetto è ottimo come suono e ricezione. Ascoltarlo in cuffia è un piacere ed è arrivato velocemente. È difficile trovare un ampli valvolare con connessione Blue tooth, e questo è assolutamente consigliabile...Inoltre il servizio di assistenza Amazon è veramente perfetto.

Before going into details below, I will say right away; this is the best price/performance value preamp&DAC I ever used considering the sound quality and so much functionality in a nicely built device.I don't claim to be an audiophile with many many years of experience but I do care about audio quality and I love trying different devices within a reasonable price range.I have tried several budget preamp/DACs/Amp/Integrated Amp combinations to this date and I will write my review based on my personal experience and comparisons.What is included in the box?- USB audio cable- A remote controller with tone controls- Bluetooth antenna to attach at the back- Power adapter (though the cable is not very long, more like a cell phone charger length)- 6N3 Tube for headphone amp (more on this later)- A USB thumb to install drivers and a software for controlling bitrate output though I don't exactly know what it does.- A quick set up guide along with specifications and descriptions of interfacesWhat is not included?- An RCA cable to connect to an amp if you wanted to use this as a DAC for a hi-fi setup- Optical sound cable- Batteries for the remote (Requires 2xAAA)Build quality- It looks and feels very solid.- I really like the looks of it, it has an industrial look with a bit of a retro feeling especially with the tube and also the wooden pieces on top.- The volume know is the main thing you use and it feels very solid and clicking sound is strong and satisfactory.- Digital display is simple to use and it has useful information with incoming sound bitrate, volume and active input selected. When you change tone controls from the remote you also see those values.- Remote looks cheaper but it does the work and you have to cut costs somewhere.Setting up- It's very straightforward. You plug the power adapter and connect to your PC with the provided USB cable or your own optical cable and that's it.Be very careful when plugging the tube on top, tube pins can be very sensitive and you don't want to bend or break them. This has nothing to do with T8, just be careful in general :)In order to use different inputs, you need to press the volume button to change the input and you can see it on the interface. USB, RCA, BT etcWhen you switch to BT for bluetooth, it goes into pairing mode and it's immediately discoverable on your mobile device. You pair it right away and it's ready to use.The USB thumb drive includes drivers and a software. I think, you don't need this and manual guide doesn't tell you to install them. It's already plug and play and you can control USB bitrate output from Windows.What is my setup?- Aiyima A07 amp- A pair of Q Acoustics 3020i speakers- Windows 10 PC with USB & Digital out- Mobile phone with bluetooth- Several audio streaming services with ultra quality/MQA output.Sound qualityI tried the device 2 different ways:1- Using with digital inputs (Bluetooth, optical, USB) and connecting it to an amp with RCA cables at the back so it functioned as a DAC2- Connecting the headphone out headphone out at the front so it functioned as a headphone preamp1- Using as a DACWith the USB interface it sounds very good. It depends on your personal taste but I thought it felt rich and warm. It sounded very similar to more expensive DAC only devices I used.It supports up to 24bit 192KHz. Make sure to change those settings on Windows for getting the maximum output.It sounded very clear and spacious (though could have been more spacious for my taste)All the instruments and vocals felt very clean and lively to my ears.Optical was similar but somehow I felt USB output produced better sound quality. Which is manageable anyway as you already have a USB cable included and you don't need to shell out extra cash for digital output. It has no benefit over USB anyway.The fact that you have tone controls on the remote control is actually very convenient and adds to the overall value of the device. Changing the settings helps you improve the sound output to match your expectations better.Bluetooth connection gave very clear and lively sound as well but do not expect it to match USB or optical interface. Bluetooth can't match the bandwidth of those inputs. For what you need as setting up a convenient wireless streaming from your phone, laptop etc, this one does the trick and it sounds pretty good for that setup.2- Using as a headphone preampNow this is what surprised me. As I said it sounds very nice as a DAC but in fact when you connect a good quality headphone, this thing sounds even better. It provides more clarity and more spaciousness.The reason for that is that when you use headphone out, it actually uses the tube on top.So keep that in mind. People use different types of tubes from different brands. I'm not an expert but I guess it could be effective here as you see the immediate difference of using a tube.So depending on your taste / preference you might actually get a headphone - RCA Y-cable and use headphone out to connect to an amp instead of RCA out at the back. This might change the experience as a DAC too.ConclusionThe main point here is the incredible value you get as I said at the very beginning. You can get more expensive DACs or preamps and they could sound better. I'm saying "they could sound better" because it depends on your taste and if you have been investing time and money in training your ears to perceive differences. To me that's not even very noticeable.Those devices would not offer you so much connectivity/functionality. For anything like that with a premium sound you'd normally have to pay A LOT more money.Also don't forget, this thing has a remote controller with tone controls which is very convenient.With this much functionality and such beautiful sound, T8 is easily the best budget headphone preamp & DAC combo I have seen out there.

Este preamplificador con amplificador de auriculares lo pude probar de un compañero de trabajo y la verdad que quedé encantado, se escucha genial con auriculares con baja sensibilidad (para los IEMs tiene un problema, puesto que son auriculares con alta sensibilidad y se escucha ruido de fondo, pero es normal teniendo en cuenta de que tiene una válvula).El sonido es muy bueno, las conexiones de bluetooth se hacen con APTX-HD, lo que le da una de las mejores calidades de sonido que ahora mismo existen para BT y el mando a distancia para controlar el preamplificador es genial para colocarlo al lado de la tele junto a un amplificador de altavoces.

This is a great little unit, paired with the matching Aiyima power amp BUT, when sending to Australia a 240v PS really should have come with it. We got around this with a travel step up unit, but would prefer to have correct PS please. Then would be quite happy to give this neat little pre-amp FIVE stars. And as with many others who have bought this item, we upgraded to a locally sourced Raytheon 5670 vacuum tube (or valve), for a better sound. Hard to get many of the other tubes recommended, at least in this country.PLEASE SEND ME A 240V POWER SUPPLY AND THEN I WILL WRITE A FULL AND MORE POSITIVE REVIEW.

I did not saw any great reviews online about it. But i think they are pretty great for the price. If u like tube sound then for sure u will love them
