AIYIMA T8 6N3 Digital Tube Preamplifier Bluetooth 5.0 Hi-Fi Headphone Vacuum Tube Preamp for Home Wireless Receiver Audio Decoder Preamp PC-USB DAC APTX + with Remote Control

I was trying to decide between this Aiyima T8 and the Douk P1, but this one won me over due to the remote control and optical in, which the P1 both lack. This (with the Aiyima A07 power amp) is replacing an SMSL AD18 that's going to my garage. I needed a versatile, inexpensive, and small preamp unit for my bedroom, and this is perfect for my needs. This and the A07 are currently feeding Emotiva B1+ speakers. My audio source is a Chromecast Audio connected to the T8 via optical in, and while the Sabre ES9018K2M isn't the newest DAC chip around, it is still very capable. I also tried the RCA, USB, and bluetooth inputs, and they all work well. One thing to note is that there's been a bit of confusion regarding the tube signal output. Some online reviews have stated that if you want the tube sound, you need to use the front 3.5mm headphone out only. After emailing with Aiyima, they confirmed that the tube signal also goes to the rear RCA out. In fact, there is no audio output at all if no tube is inserted. Anyway, I've been using a NOS 6N3P-E tube and am happy with the sound. Lastly, the bass and treble adjustments are nice feature. Since I'm using this in an upstairs bedroom where I do not want a subwoofer placed, a slight increase in bass EQ is all that my speakers need to sound more full-bodied when playing music. A slight negative though is that from what I know, the only way to adjust treble and bass is thru the remote control. If you lose or damage the remote, you're out of luck with EQ adjustments. Overall, I like this T8 a lot. I'm a fan of small budget hifi components, and this is perfect for my needs. This paired with the small and excellent A07 sound better than my outgoing AD18.

弦楽合奏などの大勢の演奏などには向きませんが、四重奏くらいまでならまあまあ悪くはないです。入力が少し大きくなると歪みが急に気になるタイプの音質なので、ソロかデュオくらいを穏やかな聴き方をするのであれば、クラシックでもジャズでも使えます。でも、このロシア球は個性ある面白い音がしますね。面白ろがって楽しむのに向いた製品ではないでしょうか。

Me gustó, compacto con aluminio y se escucha muy vivo especialmente la voces. Mis Sennheiser 620 se escuchan mejor que con mi tarjeta de audio de mi computadora Realtek o iPhone 12 Pro Max. No se distorsiona con volúmenes altos. Y le saca más jugo a mis Sennheiser. Lo que si el driver es algo viejo usándolo con la computadora de fecha 2020. No lo trabajaron más en casi 6 años. Y requiere que lo instales manualmente.

I’ve been using the AIYIMA T8 6N3 Digital Tube Preamplifier consistently since it was delivered , and honestly, it’s been a fantastic addition to my audio setup. The sound quality is super clean, with no noticeable noise or hiss, even at higher volumes. I love how many input options it has—Bluetooth, USB, optical, coaxial, and RCA—so it fits right into any system. The build quality feels solid, and the display is bright and easy to read. The remote is handy for adjusting EQ and switching inputs, though make sure you check it works out of the box since I’ve seen a few folks mention remote issues, but mine was fine

Buen producto pero caro
