To solve the Loud sound in the headphones: 1. An amplifier with not too high sensitivity 2. You need to connect a high recognition PC-USB cable Working voltage: DC12V Review: 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 interfaces What 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 etc When 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 quality I 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 DAC 2- Connecting the headphone out headphone out at the front so it functioned as a headphone preamp 1- Using as a DAC With 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 preamp Now 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. Conclusion The 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. Review: 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 vålvula). 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.

Whilst this is a very good unit, combined with matching power amp, very unfortunately the remote has died. I have put new batteries in twice, but still it will not turn the pre-amp off. Wondering if one can be purchased separately, or maybe a few - just in case this is a case of cheap and not designed to lastâŠâŠ. Would like someone from Aiyima or Amazon to respond, because pulling the power cord out of socket is not really what I want to be doing. And the unit has not been used a lot, as is part of a secondary system used with secondary TV. Please adviseâŠ..

Nachdem ich fĂŒr meinen Aiyima A07 Pro VerstĂ€rker noch einen passenden Pre-Amp brauchte, kamen der T8 und T10 aus dem gleichen Haus in die engere Auswahl. Nachdem beide technisch und preislich sehr Ă€hnlich sind, habe ich mein BauchgefĂŒhl entscheiden lassen und den T8 genommen. Ausschlaggebend war das ansprechende Design und die schlanke Bauform, die Platz spart. Wer es möglichst platzsparend will, kann den T8 auch mit dem A08 Pro kombinieren und den T8 in die dafĂŒr vorgesehene Aussparung im GehĂ€use des A08 Pro stellen. Da ich auch fĂŒr beide GerĂ€te nebeneinander genug Platz habe (sind ja beide erfreulich klein), habe ich mich aber fĂŒr den A07 Pro entschieden, der von der Leistung und vom Klang dem A08 Pro kaum (oder gar nicht) nachsteht. FĂŒr den Verzicht auf das hĂŒbsche Design und den VU Meter spart man so nochmal einiges, ohne beim Klang nennenswerte Absriche machen zu mĂŒssen. Ich muss sagen, dass der T8 fĂŒr mich die goldrichtige Entscheidung war. Die Mischung aus schlanker Bauform, schönen Farbkontrasten zwischen dem roten Encoder und dem matt schwarzen GehĂ€use, den Holzteilen und der altmodisch vor sich hin glimmenden Röhre gefĂ€llt mir einfach gut. Aber der T8 sieht nicht nur gut aus. Die Ausstattung des Pre-Amps ist mit RCA, Bluetooth, beiden digitalen Ins (optisch und Co-Ax) und sogar USB vollstĂ€ndig. Und an allen EingĂ€ngen klingt der T8 richtig gut. In Kombination mit dem A07 Pro als Amp hat man erstaunlich groĂen Sound fĂŒr erfreulich kleines Geld. Man sollte nur daran denken, dass beide GerĂ€te ĂŒber eine 2-Band Klangregelung verfĂŒgen. Ich stelle den T8 daher gerne auf neutral und regle den Klang, falls nötig, dann am A07 Pro, da dessen analoge Encoder mir feinfĂŒhliger erscheinen. Das heiĂt aber nicht, dass man am T8 den Klang nicht ebenfalls sehr gut regeln könnte. Mit jeweils +/- 10 Stufen sind auch am T8 Raumprobleme oder Ă€hnliches schnell ausgeglichen. Schade nur, dass man den Klang nicht auch direkt am GerĂ€t regeln kann. Dies ist nur mit der Fernbedienung möglich, die aber leider China typisch keinen sehr hochwertigen Eindruck macht. FĂŒr den Fall, dass die Fernbedienung ausfallen sollte, lasse ich daher die Klangregelung am T8 auf neutral und regle denn den Sound am VerstĂ€rker. Die Umschaltung der Eingangquelle am T8 verlĂ€uft gerĂ€uschlos. Am USB Anschluss lĂ€sst sich im (Windows-)Treiber die ĂbertragungsqualitĂ€t einstellen (bis 192k / 24bit) und alle Modi funktionieren bei mir auch problemlos. Die Verarbeitung lĂ€sst keine Kritik aufkommen. Das GehĂ€use besteht aus sauber verarbeitetem Stahlblech, der einzelne Drehregler funktioniert gut und fĂŒhlt sich wertig an. ZusĂ€tzlich kann man den Regler noch drĂŒcken, um die Klangquelle zu wechseln. Hier fehlt mir nur (wie bereits erwĂ€hnt) noch die Möglichkeit, auch den EQ direkt am T8 zu regeln. Das OLED ist schön hell und gut ablesbar. Einzig das Kabel des Netzteils dĂŒrfte fĂŒr meinen Geschmack gerne ein gutes StĂŒck lĂ€nger sein. Nicht jeder hat die Steckdosenleiste in unmittelbarer NĂ€he der Amps stehen. Hier wĂ€re ein Netzteil zu bevorzugen, das einen KaltgerĂ€teanschluss hat, so dass man ein Kabel in WunschlĂ€nge dazu kaufen könnte. Von den genannten Kleinigkeiten abgesehen hat Aiyima beim T8 aber fast alles richtig gemacht, was die Verarbeitung und die Bedienung betrifft. Auch beim Klang enttĂ€uscht der T8 nicht. Zusammen mit dem A07 Pro zaubert der T8 eine eindrucksvolle Klangkulisse, die man fĂŒr den Preis der beiden GerĂ€te so gar nicht erwarten wĂŒrde. Dabei ist der T8 nicht auf eine oder wenige Musikrichtungen beschrĂ€nkt. Ich hatte sowohl mit anspruchsvollem Material wie filigranen BeckenklĂ€ngen bei Live-Aufnahmen als auch mit Techno Musik (2 Unlimited lassen grĂŒĂen) und so ziemlich allem dazwischen einfach jede Menge SpaĂ. Obwohl auch Feinheiten schön heraus gearbeitet wurden, klang es nie anstrengend oder ĂŒberbetont. Stimmen und Naturinstrumente kommen in den Mitten und Höhen schön zur Geltung und gleichzeitig wirkt der Bass niemals zurĂŒckhaltend, obwohl die Mischung aus T8 und A07 Pro hier eher neutral abgestimmt wirkte. Andere GerĂ€te schummeln da gerne mit ĂŒberhöhtem Bass, was viele Hörer mögen. Aber dafĂŒr gibt es ja die Klangregelung an beiden GerĂ€ten, mit der solche persönlichen Dinge schnell geregelt sind. Ich bin mit dem T8 insgessamt rundum zufrieden. Zusammen mit dem A07 Pro habe ich eine sehr erschwingliche und vielseitige Kombo, die fĂŒr den aufgerufenen Preis erstaunlich gut klingt und Leistung satt bietet. Ich kann den T8 als flexiblen und gut klingenden Pre-Amp nur empfehlen. Dass er dazu auch noch schick aussieht, wird vieleicht fĂŒr den Einen oder Anderen noch zusĂ€tzlich freuen. Ich wĂŒrde das GerĂ€t jederzeit wieder kaufen.
