I bought this in HiYO Silver(!) to use with my heaphone setup here in the Bat-Cave. It is excellent in doing what it says it does and that being allowing me to tailor the music I bought and paid for so that I can hear as I want and not just as so much fAdCopy today claims, "...as the fArteeest intended". The artist intended for you to buy and enjoy their music and this excellent performing (and looking!) EQ does just that. I use it with an Emotiva XDA-2, an S.M.S.L. smurtified THX headphone amp w/balanced and SE in/ouputs and a WONDERFUL Denon HEOS Link for my paid for music services: Pandora, SiriusXM and Amazon UHD Music. They all sound wonderful through this setup and It works superbly across the 5 'phones that to date I have used with it. You will not be disappointed. Well...Unless you enjoy straining to hear bits instead of music. I can't hear a single "bit", 0, 1 or otherwise. What I am hearing is MY soundtrack, beautifully reproduced and tailored to MY tastes by a compact, well built and good looking piece of audio equipment. I may get one for a relative for his headphone use. It is that good! Trust me. I know what I'm doin' when I'm reviewin'. Thanks! TheBatman

I was torn between this and the Schiit Lokius, but this was less than half the price and did the job just about as well (I already have a Schiit Loki). The main thing I discovered was that the tubes actually colored the sound a little bit, giving all frequencies a warmer sound, which is what I was after. The main reason I got it was the balance adjusting screw ( I guess the design team ran out of space to give it a proper knob) on the far right end of the rank of knobs which I needed for a slight imbalance in my hearing when listening on headphones. This is also a pre-amp, giving it a feature that the Loki and Lokius don't have (and probably don't need). Also, I'm a sucker for fun-fi, Chi-fi gadgets and this unit looks really cool next to my Pro-Ject S2 tube phono pre-amp. It's a plus-value for us budget audiophile wanna-be's who can only afford to buy into tiny-tubeland. Works for me.

Let me start with saying I love this product it works perfectly and the tubes light up great but it doesn't work well directly on a record player. This product does work well as a preamp but it's really only works as a EQ for a record player. The reason for this is it can't amplify the signal enough for it to work with a amp well which can be solved with phono preamp before it. Once I had it set up it sounds amazing and the control is perfect it add a warmth to the music I have yet to try the xlr outputs but it will just make it even better. Overall great product well made but just watch out if your buying this for a record player pre amp

It worked okay for about a month, and then it started making a popping sound in my left speaker. I think one of the vacuum tubes is bad. I can get the popping sound to stop when I swap out the tubes for a pair of Mullard tubes that I have. It’s disappointing that the tube only lasted a month. The loud popping could have damaged my speaker.

I used to have a Marantz receiver/amplifier. I had a separate equalizer. It took most of my family to move them from room to room. The amp was HEAVY. When I got this little thing I thought it was junk and would not do anything like the old stuff. I was totally wrong. I am running a turntable through it into a set of reference speakers. The sound is amazing. It has a 7 band graphic (I think, might be 6) and it can get loud enough to make my speakers clip. I listened to Led Zeppelin II just now and my wife ran down the stairs asking me to turn it down because it was shaking the art on her office wall. Your results may vary, but I am thrilled with this little guy.

So I use it as an EQ for a Bluetooth receiver but might have different plans for it in the future. It works as a great EQ for me. Tubes look cool but I also have a tube amp so that might be overkill for me. lol. On the suggestion of another review I was thinking about running a record player through it but might need a pre amp. I’ll try it without and update this review if it works.

Warning, do not buy! I've been trying to get Douk to honor the warranty and so far I haven't heard anything from them. I've had this for a few months and I want to toss it in the trash bin. On my unit, there is noticable distortion whenever I use it. However once the tubes warm up, the audio becomes distorted beyond recognition. Mid range frequencies like guitar, piano and vocals are especially thrashed. Delicate songs with beautiful harmonies sound like the Dark Lord Sauron's flatulence when playing through it. I've had full range pop songs sound like a drunken Jim Morrison vomiting to elevator music. This piece of garbage is nothing but e-waste. Don't buy.

I have a "modern" high-end receiver, which basically takes all of the controls away - lacking even a treble and bass adjustment in favor of it's own built-in modes. Well, anyway, oftentimes I really want and need more treble or bass - and here it is! Update: I've had this unit for over a month now and I am even MORE pleased than before. The equalization can make my high-end Pioneer receiver sound near perfect, even with the CD itself is poorly equalized in the mix! I use "Line" input into the Power amp stage so now I can tone-down or tone-up one or more bands of the poorly mixed CDs - something NO poweramp can do. I also like the "organic" tubyness" of the unit. It makes vocals sound very real. I do keep the gain (volume) at about 10:00 so as not to overdo the influence of the tubes, and also give them plenty of headroom to do their job.
