Douk AudioP1 Vacuum Tube Bluetooth Preamplifier, GE5654 Audio Preamp, Hi-Fi Headphone Amp, Stereo Wireless Receiver with USB DAC & APTX-HD for Home Theater Amplifier/Active Speaker

SETUP: I have a turntable with RCA out, active AudioEngine Speakers with RCA input and my home computer in my home office and just upgraded to some solid audiophile headphones.OBJECTIVE: To have the ability to send high quality entry audiophile sound to my speakers and headphones from my turntable and or laptop--- on a budget!Did a lot of shaking of the internet and research trying to get something with RCA & PC Input and RCA Out with Headphone output. Could find things way more than I needed or smaller units that were just not right. Then a link of a link of a link mentioned this device -WITH tube sound (and resulting bonus mad scientist nerd look). THIS FIT THE BILL PERFECT!For the low price point I thought it might be a sad build quality or weak sound - but after a couple months of use, this has exceeded my expectations (calibration = I'm a newbie audiophile). The sound both from my vinyl and my PC (spotify and live audio streams) are deep and rich with new tonal discoveries to old favs both through my speakers and even more so on the headphones. The bass/treble adjustments offer even more possibilities for tuning the sound and exploring the new broad sonic stage I have to play with.The build quality is obviously not something you want to take into a foxhole - but very solid feel and look. Only possible caveat is I have big hands so the switch to flip between inputs seems little - but a niggle at best.Likewise, I feel unsure of getting the connector slots lined up with new tubes but that is likely my novice skill at it than the device.Stealing a tip from elsewhere, I got matched/tested 5654W tubes from Riverstone to put in over the stock ones it ships with - have not tried the stock ones to have a basis for comparison.FINAL VERDICT: Great device that does the job at a great price point and highly recommend!

This is an amazing affordable little pre-amp with great sound and tonal features, i.e. the volume, bass and treble control are spot on. I strictly use it as a pre-amp, not as a headphone amp, although it can do that too. I find the looks stunning and love that I can switch the lighting from a tub-glow-like amber to a blue. It works decently over Bluetooth but I use it mostly with the RCA inputs. MAC>>DAC>>RCA>>Douk P1>>RCA>>Power Amp>>Speakers. The small size and low price should not diminish the fact that this little pre-amp can hold it's own against many much pricier options. I've tried many other pre-amps and DACs with built-in pre-amps to connect to my variety of power amps (both tube and solid state), and this Douk P1 never disappoints me. Every time my main pre-amp (Schiit Freya+) breaks (5+ times in a year so far) and I have to send the Freya back to Schitt for repairs, I take out the little Douk P1 to replace it and every time I am amazed. Obviously it only has one RCA input and one RCA output, but it always works. I did add a iFi linear ("silent") power supply (wall wart style) to further enhance the sound but the standard power supply seems to work fine too. You can also buy new tubes for it quite easily if you like tube rolling, but in my opinion the standard tubes sound great and last a very long time as they're not getting very warm. Amazing little until, probably value for dollar (and practicality) the best purchase I made on my audiophile journey so far!

The Douk P1 is a good amp at the $90ish price point. Audio is clear and defined. The bass and treble controls work well without increasing distortion. Bluetooth connects easily.Used this to drive some HD599s and HD600s and both sound good.There is one small issue - when no music is playing, there is some small static in the left channel. I've used three of these and they all had this issue. I don't hear the static when music is playing.I paired this with an Apple TV and movies and tv sound fantastic.As a inexpensive, bluetooth enabled headphone amp I'd say it is good value for money.
