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

Nice smooth sound for this price. Was surprised at how quickly it turns on considering it has bulbs. The Bluetooth function is easy to use and the sound is as good as my Raspberry Pi via RCA. Would buy again.

Bought for occasional listening while working on a hobby. Easy controls, easy setup. It won't replace my Cronus, but it will stand alongside my NAD. Let's see how it holds up over time. Too new to rate reliability (running 4 hours).

* Volume control, the dot that shows how much it is, can be hard to see if it's not illuminated. Don't use solid state amps (I'm new to this world of amps). - Replaced the included audio cable with a better one that reduces static electricity. - Replaced the USB cable of my external sound card with an additional one. Reduction of static electricity. The problem does not occur with either my laptop or my cell phone as sources. * I'll try to buy some ferrite cores and play around with them, hope…

Surprisingly good for the price! You have to let the tube warm up a bit and it sounds MUCH better. I plan to change the Chinese tube to GE. If you look at this amp from the inside it looks a little flimsy and simplistic in design but the metal case is very nice and the thing has weight. The volume control works very well, better than my expensive NAD amp. The aesthetics of this amp are amazing in my opinion! The deep amber glow and the mirror behind the lamp make this thing look like it costs…

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…

I ended up using two of these for an unintended use - as external amplifiers for my surround sound (Polk LSiM 702) and as height speakers (Klipsch R-41M) to relieve my Denon X3200W receiver .

The sound is amazing! Of course I made some improvements, e.g. B. Replaced the power cord and audio cable with better ones than the factory ones due to their poor performance. What I would recommend is replacing the power cord, it improves the sound by 40-50% and the amp is delivering 100% of its power. But the amplifier itself is high-quality, strong and solid, the sound is harmonious and pleasant; I chose this amp because it is class-ab, which I think is very difficult to compare with a…

Плюсы:1 - Усилитель для наушников высокой мощности2 - Надежная конструкция3 - Простота сопряжения по Bluetooth4 - Хороший выбор аксессуаровМинусы:1 - Светодиод под вакуумной лампойКомментарии: Физически этот усилитель для наушников довольно большой и тяжелый по сравнению с почти всем в его цене диапазон and that's good. It has a very large transformer underneath and a well filtered power supply. At the top is a single 6N3 (5670) vacuum tube, cleverly placed in front of a mirror-polished metal…
