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

I'm impressed. This little receiver/amp was a good buy for me; and worth the money. I have it hooked to a turntable and some floor-standing speakers built in the 1970s (with 10" woofers) and I was a little worried it wouldn't have the power to make them sound good. I was wrong. I'm not sure it's 160 watts per channel (not quite as much bass depth as a larger amp at lower volumes) but it does sound really good/rich/clean at mid to high volume. Somehow it does this with the included 32vdc power supply. The directions say you can upgrade the power supply to a 35v one for more power but I'm satisfied.I love the clean aesthetic and physical switches/knobs. Came with genuine GE tubes. Bluetooth tunes sound super clean and amazing and I love that it connects quickly and silently (no confirmation beeps or whatever). The amp takes a few minutes to warm up and the audio sounds a little hollow until it does warm up but that's expected with a tube/hybrid amp.Overall, I'm very happy with this amp and would definitely buy other Douk Audio products.

As described ,good and cheap

Don’t waste your money on this product. I was initially happy with this amp as it seemed like decent quality at a good price point. However after having it for less than a year it started to have issues. The connection to one of my speakers stopped working even after many attempts to re-wire/troubleshoot, and shortly after that the Bluetooth capability just died!! Reached out to customer support multiple times and they ghosted me (obviously because they know their product is a scam). Please don’t waste your money on a cheaply made Chinese product like this that will turn into e-waste in a few months. Better to invest in something that will last!

Very happy with this so far. Bluetooth works great and the phono amp appears to have good sound although I suspect a true audiophile would argue this. I wanted something small that could handle powering my Cerwin Vega 300 watt 4-8 ohm speakers and this unit had no issue rising to the occasion. The amount of heat it gives off is nothing compared to type A or A/B amps so I am happy. The tone/volume dials turn and feel high end. Toggle switches not so much but that doesn’t take away from the quality. If you are looking for an all inclusive compact receiver with enough power for pretty much anything outside of hosting a real rock concert this will cover you well.

2 years in and finally getting to writing a review for this outstanding product. I have encountered no technical issues with this device whatsoever. Simply put this is the coolest electronic device I have ever owned. There is nothing out there in this price range or certainly in this size that can do everything that this little miracle can do. It has phono line in for turntables, auxiliary line, Hi-Fi Bluetooth connections which works amazing with my Hi-Fi streaming apps at 24 bit, subwoofer out. 100 w per channel. This thing is LOUD on my standing speakers I dedicated to this device. I have been using this device heavily for the past 2 years as it runs my living room bookshelf system and again after 2 years there is simply nothing out there that can compete with what this is capable of doing. Sound quality with bass boost and treble control is outstanding for a device of this size and price. Can an audiophile spend thousands of dollars and recreate something that sounds better. Of course! That fits in the palm of your hand for $150 or less? I don't think so.

[Edit 7/23/23: 1 star removed because Bluetooth stopped working today, and upon reading other forums including Douk's own, this appears to be a common issue with this unit. However, Douk Audio support is great, and I would expect they will send out a replacement Bluetooth board to put into the unit (easy install, no soldering). Will update this review with a 5 star rating again assuming this is what happens. EDIT a couple months later: yes, this is what happened, thank you Douk Audio!)This little integrated amp does so many things and does them well: Phono preamp, power amp, vacuum tube stage, EQ controls, LFE sub out (game changer for my sub), Bluetooth 5.0 w/ APTX, and to top it off, a beautiful aesthetic design. Most importantly, it sounds downright amazing for its size and power. I switched from a Topping TP22 amp and Nobsound Hifi 6J Bluetooth tube preamp, and the change is unmistakable. Way punchier and tighter bass with the LFE out, cleaner mids and highs, much stronger dynamics in general, and no matter my audio source - vinyl, CD, tape, or BT - it all sounds great.Two caveats - 1) when using a sub via the LFE output, the bass control becomes more of a speaker crossover than an actual EQ, adjusting the mid-bass frequencies in your speakers (like 200-400Hz) and nothing in the sub. This is a little unfortunate as it means separately controlling the sub volume, but not a huge deal. 2) I had to return a unit due to a buzzing sound in the right speaker outs when in Bluetooth mode. The replacement unit had the same issue as well, but I realized by disconnecting the antenna, the noise went away. I suppose this might be BT/RF/wireless "noise" in the environment, combined with the very aggressive 320W amp powering the signal. If you get this same issue in your unit, just disconnect the antenna, it's not super necessary anyway.All said, I cannot believe this amp is the price that it is. If you have a similar setup with multiple sources and want strong, punchy, clear yet warm sound, and don't want to spend big money get the X1.

Works great and easy setup, only complaint would be to have another rca output. But sound is great, nice that you can switch between blue led and orange (amberish) led. Had it out of the box and playing music from my record player in under 5 min. Very small footprint which is another bonus.
