Beautiful class D amps. Sound in much better than I thought it would. The hook up is easy. No drop outs on the Wi Fi. . Generally a great 100 watt x 2 amp

I use the unit solely as a preamp into KRK powered studio monitors. I bought it for my record player, but I also use the blue tooth function for playing video/music from the PC. I'm a guitarist and know quite a bit about tube amps, so let me dispel some things others have said in reviews.1. The tubes are not for looks, they are used in the preamp circuit, one is for left side the other is for right.2. If you want to use this as a preamp, simply use the aux out jack in the rear to input into your amp or powered speakers. You can also use the power amp functionality if your using passive speakers.3. The VU meter works perfectly fine.4. The EQ on the unit work great, HI/Low. very warm sounding unit.5. The blue tooth function is great, I didn't test the range, but when I switch from RCA (record player) to blue tooth, it connects very fast which is nice.6. I run the unit in an enclosed cabinet, I have no issues with heat. It's not like a guitar amp that has power tubes, your not gonna get that hot. However I am only using the preamp side, using the amp outputs may generate more heat, but I cant imagine its much.Bang for the buck, this thing is amazing and totally what I needed for the record player. Boosts the signal great and adds warmth, added benefit of blue tooth input.Also, if you want to upgrade the sound (a bit warmer and a bit better volume) update to this model of tubes. I compared side by side, very nice. (5654W)https://www.amazon.com/dp/B01BFJDTW0?ref=ppx_yo2ov_dt_b_fed_asin_title

I purchased this amp along with some Fluance speakers so I could have a very carefully controlled test bed for other components, speakers, etc. So far, pleasantly surprised at how punchy and strong this little amp is. I can quickly hook things up to this amp and run tests. I measured all the outputs with my diagnostic equipment and it tested out to the specifications listed for this amp. A very simple, powerful, punchy amp at a good price. Nice.

Sounds pretty good out of the box and can be upgraded with better tubes, external DAC, etc. I have a dozen other amps including the Fosi ZA3, vintage Kenwood and Marrantz, AVRs from Cambridge, Denon, Yamaha, NAD.The built-in DAC isn't great so I use an external DAC that I prefer, it's just the old $20 FIIO Taishan. I go optical out from my TV into the FIIO DAC and then RCA analog into the Douk preamp/amp, which is powering a pair of vintage ADS bookshelf speakers. Recently tried it with my SMSL SU-1 DAC and that was even better.Needed a small form factor to fit the space. Been using it for 18 months, with no issues. The tubes definitely change the sound. It's fun to experiment with different tubes and they're readily available on eBay, often for $20-30 or so for a matched pair.Everyone on Amazon gets the Riverstone Audio JAN 5654W tubes that are marketed as an "upgrade" but I didn't really care for them. Sounded dull and rolled off to my ears. I prefer old soviet-era Voshkod "rocket" tubes. They have a more dynamic hifi sound with extended highs and lows.The VU meter doesn't work very well for me (maybe by speakers are too small/efficient to move the needle at regular listening volume?) but that's kind of a gimmick anyway. Overall worth it for the tube preamp and TI class-D amplifier functions that I use it for.This can be a good option if you like tubes or want to try them out. Also good if you need the digital inputs and Bluetooth built-in, as those are usable if not the greatest.

Hard to find fault with anything here. Setup was about 5 minutes. I just plugged the tubes in, swapped the cables from my cheap old receiver and had rich, dynamic music. Controls, overall tone, remote, and bluetooth are all fantastic. An eq will round it out nicely, but its great as is. The clarity and (yes) punch at even low to mid volume is impressive. Analogue synths and strings sound amazing. I can’t believe the price to value ratio here. If you’re on the fence, just kick the fence over and snag one of these for a great entry level tube amp.

It is amazing what a nice sound this little thing can provide. Especially I like warmth of the sound (kind of softness) produced by tubes. Pair it with Polk's speakers (like I did) and you would just "bath" in music all day long.

Edit: Changing from 2 to 5 stars. It was the ac adapter that died, not the unit.I bought this to redo my PC sound setup for music production and also incorporate my tv into the mix with the optical in.Everything went as planned. It sounds great, but I'm coming from a smsl setup so it didn't blow me away or anything. But for the price and additional inputs and the cool aesthetics I was super happy. The remote being a huge huge plus.After a few weeks I watch some YouTube videos after waking up. Everything is great. Go to Hogwarts for a bit. Great.I leave for the day and when I come home it just won't turn on. Nada. Completely dead.I don't smell any magic smoke. Luckily I'm within my return time with Amazon so I don't have to deal with the manufacturer. I'll update this review when my new unit arrives tomorrow.The only thing that I don't like about this amp is what everyone else complains about. It'll go into standby if there is no sound for several seconds. I can deal with that. I don't see what everyone else is talking about with db scale not doing anything. It doesn't on low volume but it does when you turn it up. That's understandable to me.More importantly to me is that the volume goes up and down in notches. So the very lowest volume is still louder than I would like watching stuff at night when I fall asleep. That may just be the way optical comes out of my tv, I'm not sure yet.For the price, aesthetics and integrated DAC, I'm not sure it can be beat.
