[2021 Updated] AIYIMA Tube T7 Audio 6N3 Tube Preamp Bluetooth 5.0 Warm Vacuum Buffer Preamplifier with Treble Bass Tone - Ideal for Enhancing Home Theater Systems Review

This is a good preamp at a good price. I never used the lamps supplied by China, I immediately installed 5670 US military lamps. Compared to my old preamp, which used smaller 6j1 tubes, the bass is noticeably punchier and the tone warmer and more tube-like. I love the unique 3D effect lamps brought to stereo. Aesthetically this one looks a lot better too, with the big bright 5670 tubes sticking out (although the 5670 has a lower profile than the Russian or Chinese versions). This preamp is…

So I got this preamp after using its little brother with 6J1 tubes which I thought were excellent but a warm natural produce sound. that you can listen to for hours without getting tired. The sound is very similar to vinyl. So I decided to give the older brother a try. It's a bit more expensive. The sound quality is excellent, very comparable to the 6J1, however the output levels were significantly lower than the 6J1 which meant you had to turn up the amp. So I brought it back, but you can't go

I like this device very much. I have a 2.0 stereo with powerful floorstanding speakers in my garage when I'm working on my next mechanical project, and my receiver didn't have Bluetooth capability. I previously bought an Aiyama 6J1 preamp which sounded great but had a hard time playing quieter music and audio books. I contacted Sandy from customer service and was told that the improved Bluetooth capabilities in the T7 would fix the problem. I was very satisfied with the friendly customer…

package arrives in good condition. Delivery a little slower than expected but it finally arrived before Christmas. We have a high quality preamp. The body of the box is quite heavy and solidly made of aluminium. The design is simple and the function is easy to use. I connected this tiny preamp to a pair of powered bookshelf speakers via a Bluetooth connection. The sound is so rich, clear and magical. As expected, bass and treble controls can improve the sound. The QCC3003 model appears in your…

This is the only Southeast Asian item I have ever purchased that has not disappointed. The body is a solid extruded aluminum with well machined end plates. The switches have a nice solid click when moved. The potentiometers are nice and smooth and don't make any noise in the sound when operated. sound quality? Uh, it's Bluetooth. How good can it actually be. This does not reflect the product, only the technology. My stereo gives out all the flaws in sound reproduction. This is exactly what I…

This expression indicates my age, as does the rubbish heap in the photo where the Aiyima Tube T7 has found a home. I also ordered upgraded lamps but they haven't arrived yet. This is my impression of the supplied tubes. The connection was easy. I connected the USB to the Topping DAC to the inputs of the T7 and then connected the output to the Marantz receiver (bottom unit) ribbon cable. It drives a pair of Klipsch Heresies and a 15" 250W subwoofer. I've also connected my Android phone to…
