Well it didn’t come with the power supply I ordered

Well it didn’t come with the power supply I ordered. Paid extra money for the 48v power supply and was sent a 36v supply. Sent multiple emails and no response. If they would respond I would request a return and refund. Went another direction. As for the amp haven’t used it. Want to return it.

Works well, a year later still working well

arrived fine, shipped fine, a year later and it still works - sound quality is pretty good, not awesome but pretty good,

Works as advertised except for power output

The media could not be loaded.

I took 2 stars off because of the advertising saying this is a 300w x 2 amp.Also there was no remote control included as it was advertised.The included power supply can only supply 150 watts total, and no amp is 100% efficient.This is realistically about 60-70w x 2 into 4 ohms.Also I upgraded the power supply to a 48v 400 watt model and there was no audible difference, so don't bother with that.The bluetooth pairing and connectivity was fine, as was the line in.This review is for the PLUS version (without tubes), not the PRO version (with tubes). The reviews seem to be getting lumped together so I wanted to distinguish it.

Small things can do big things!

I hook up this amplifier (or receiver) to my passive 5 inch bookshelf speakers. My bookshelf speakers were powered active speakers but a month ago, they suddenly died on me so I converted them to passive speakers.I didn't expect much from the small, tiny amplifier, and I wanted to use my current speakers.Once it turned on, i was surprised by the power and the sound. I know I have decent speakers, but they sound better now than they did before. Not only that, the lighted VU meter with the lighted vacuum tubes look so cute and reminds me of the steam funk look. I'm not sure how long the vacuum tubes would last but I am liking this little thing!

Douk Small Tube Amp

This small tube amp is about the size of the palm of my hand. It utilizes two vintage tubes which are placed in the sockets on the top. The amp connected easily to my phone through bluetooth, and sounded good. The bluetooth has a nice range. The volume control does not have any numbers on in it or stop point so you just have to get the feel of it. I have two receivers that were purchased long ago and they sound better than this however for the size of this unit it sounds fantastic. I think its great for a small space. Hook it up to small speakers and its perfect, play anything on your phone. If you are having a party outside this is perfect because of its size. On the back there are speaker connections, and line in so you can plug in a tape player or whatever you'd like, and a power input which is supplied as well as a remote control. Very interesting. I bought it more out of curiosity but I will find a use for it
