Douk Audio X1

I bought this to replace a tiring Denon from the 90's. I liked the phono input with ground, bluetooth and sub out, as I do run a Yorkville powered sub to complement the power hungry Heresy 2 Klipsch's that I use. It arrived nicely packaged, was easy to wire in and powered right up. I do like vacuum tubes.....this thing is tube on the preamp side only, which is fine by me as the long term maintenance should be less costly than an amp with output tubes. It's compact, well built and sounds great. Bluetooth was as good as could be expected, but the phono input is really quite surprising. Vinyl sounds incredible. I don't think I could find better for the dollar spent than this.

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

[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.

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

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.
