Douk Audio HiFi Stereo Bluetooth 5.0 Vacuum Tube Amplifier MM Phono Amp for Turntables 320W

Has lasted me a few years so far with no problems. I haven’t even treated it very well; I’ve taken out the tubes while it’s running, wired its output to headphones, etc. and it has no problems and sounds normal. It has very low total harmonic distortion so I don’t personally notice a tube sound at all but it looks cool with the tube LEDs and I like that it uses tubes for vibes. Bluetooth, rca and phono comparability and rca subwoofer connection are all very convenient. The EQ is perfect because it’s enough to shape the sound to your liking but simple enough that I don’t overthink the settings. Bass boost feature is useful for parties. Definitely a high quality product.

Love this amp. I have and have had so many amos in my life but never this small footprint type. I have this running a turntable and speakers only. Boy will it put out the power, sounds incredibly clean. I also love the Bluetooth function which works incredibly well. Had for a year now with zero issues. Would definitely buy again. Very impressed. If your on the fence I would not hesitate purchasing the Douk amp.

I had low expectations, purchasing this while my Rotel is being repaired but I’m very impressed with it. Adequate punch and tonally quite good. Easy Bluetooth connectivity; Unbeatable for the price

Perfecto y sin ningún tipo de fallo, muy bien empacado y luce muchísimo.

I ordered this not expecting to be blown away by such a relatively cheap little amp, but here I am. In my spare time, I repair vintage receivers and speakers, along with other electronics. Recently I wanted some speakers in a place that wouldn’t fit my b&o beomaster 8000, so I went looking. I needed something that had a built in phono amp/ground, rca inputs for airplay, and Bluetooth. This checked the requirements, and had sufficient power to drive my 80s Bose 501s. Along with that, the tube pre-amp was a bonus. Construction is solid, heavy, and good looking. And the wide range of DC voltages is nice, so if the bulky adaptor (24V 5A) ever takes a dump, I can replace it easily. Sound quality is typical of an AB without the preamp, and with the preamp, it’s more reminiscent of my B&O Class A mono block. Bluetooth works without issue, and connects to my iPhone 12 Pro Max quickly, with no beep that other receivers have (that irritates me). My technics plays perfectly through it, and the phono signal is boosted to a good stable level. The ground works fine with no hum even at high levels. But the big surprise are the tubes that came with it. Being made in China by a company I’ve never heard of, I expected the tubes to either be sub par Soviet or fake altogether. My jaw dropped when I saw genuine, made-in-the-USA, NOS, General Electric, 5654Ws in the box. And not just any 5654Ws, but the infamous JAN type. JANs are the mil-spec type designed for longevity and performance, and are considered by many to be one of the best for audio use. I keep a few in my personal stash for repairs because I know they’ll probably never go bad. Overall, I’m impressed. For the size, form factor, number of inputs, sound quality, and price, I have no regrets.
