Review on AIYIMA Tube T4 HiFi Stereo Audio Power Amplifier Bluetooth 5.1 Vacuum Tube Amp - 100Wx2 Stereo Receiver APTX-HD for Home Theater System + DC 32V Power Adapter (Black- T4) by Ben Karlen

I connected KEF Q150 8 ohm speakers to this Aiyima Tube-T4 amp and connected the input between Bluetooth (my phone or computer) and RCA connectors (my laptop) changed. KEFs are very transparent and detailed in English, and I've been listening to Spotify playlists (at the highest resolution). Having never owned a tube amp before, I figured this Aiyima amp would serve as an inexpensive experimental amp. access to this technology. It may be cheap, but it's definitely not low quality. The sound this amp plays through the KEF is wonderful. All the details are there and the presentation lives. Orchestral music seems to benefit the most from lamps as they add a subtle and pleasing "live" aura to the music. There's more than enough power to propel the KEF to levels I never want to hear. I'm glad there are separate bass and treble controls, although I've found it's best to keep them in the middle, except at very low volumes when that helps boost both treble and bass . Perhaps most tellingly for me, I have no desire to go back to my solid state amp. I am definitely happy with the purchase of this amp. It was much fun.
