Review on 🎧 INFI Audio Tube Amplifier Headphone Amplifier: Bluetooth Home Theater Stereo Receiver Desktop 60W Class AB Hybrid Integrated Amp by Tiffany Young

I ended up using two of these for unintended use - as external amplifiers for my surround sound (Polk LSiM 702) and as overhead speakers (Klipsch R -41M) to survive some stress my Denon X3200W receiver. I originally bought these to drive several headphones and they do very well for this purpose with the smooth sound of a class AB amp. I have a GE 5670w bulb on one of them and I would say the standard bulbs are fine. The advantage of my setup is that I switch the input to AUX when watching movies and to BT when I just want to listen to music through my LSiM or Height speakers. My LSiMs are quite difficult to use and I'm very impressed that they have enough power for average listening levels. The all-new Dayton Audio HTA50BT is a little better if you're willing to spend more on headphones. My Dayton Audio HTA100BT is the best AB class amp I have (no headphone out) but both are double the price of this unit. Update: I ended up buying a third device. It looks like I'm pumping out all the previously used units. Upgraded them all to a GE 5670w tube.
