DEAFidelity Hybrid Hi-Fi Integrated Vacuum Tube Amplifier in Conjunction with Bluetooth 4.0 and USB Input, Tubes 6N13Px2, 6F1x2, Black

Looks great. Sounds goods.

My first tube anything in over 20 years. Set up is simple. Bluetooth pairing as easy as turning it on. Put in Miles Davis, Kind of Blue. At first I was disappointed, flat tones low volume. I've forgotten over the years that tubes need to warm up! What a beautiful, full sound. Much more than just volume, it has that live surrounding tone. I'm running the amp through Kenwood Bass Reflex towers with a separate sub woofer. I couldn't be happier. I highly recommend it.

Outstanding sound. You could spend 10x as much and not get better sound.

Sound quality is excellent, vocal imaging is really good and it sounds good on every type of music I've tested so far. Blue tooth reception works well but music will skip if reception drifts off. Haven't tried the USB player yet, but thats next on the list. Subwoofer output was too low for my subwoofers auto on to work properly but thats a minor complaint. One other complaint is the instruction manual isn't in english!

this would have been an easy 5 star except for the fact the instruction manual was printed in Chinese there is no way to figure out how to use some of the functions as in the USB hook up or whether or not you can stream using it. That's just too bad because really it is a great unit but if you can't read how to use it then your screwed.

Was broken out of the box.

Thanks to other's reviews & replies, I bought this amp from Fee Bay (seller Eureka Fair) since not currently offered here. This amp exceeds all my expectations and is incredible.The bluetooth works great. Doesn't sound nearly as harsh as prev generations. I love the usb. Turn off computer & listen with no computer noise in background. It also remembers place of last song even if switching usb sticks! There might be some psycho acoustic processing. Snare drums that are normally very wet sound much much drier.
