Product description

Default 6K4 tubes, and can be directly replaced by 6J1/6J4/GE5654/6AK5/6*1n to enjoy HiFi sound of different styles.

U-disk and TF card inputs support MP3 and other lossless format such as APE, FLAC, WAV, WMA. No need for any driver, plug and play, convenient to enjoy fun even on the road or outdoors.

Warm tips:
1. P2 is a tube preamp which needs to work with amplifiers or active speakers, cannot drive passive speakers or used with turntables directly. In RCA input mode, the previous / next song function is invalid.
2. The USB interface only supports U-disk and USB 2.0 thumbdrive, not support PC-USB. And the RCA and 3.5mm headphone jack can output at the same time.

4.0 out of 5 stars Sounds Great!
Reviewed in the United States on 3 October 2020
Was skeptical about buying this with no reviews but gave it a shot. Sounds really good and the Bluetooth connection to my iPhone is solid. It is a bit noisy/static/crackly when first turned on for a minute or so but it may be a weak tube thing, but after it warms up its rock solid. If it holds up I'll get better quality tubes for it. The only negative thing, and I knew this beforehand, is the lack of a volume knob but the pushbuttons and remote work just fine, just hope they hold up. Tested some mp3's on a flash drive and it worked without issue. Very happy with the purchase and may try some of the other Douk products. I'll update after a week or two to see if everything works out.

5.0 out of 5 stars Blown away!
Reviewed in the United States on 28 March 2021
So I bought this to test out before adding to my main rig in my listening room. Not new to audiophelia, but new to Tube preamp/amplifers. I ran this for 3 months on stock tubes through a Fosi Audio Class D TPA3116 Mini Amplifier and kept thinking, it's got body, but the highs are definitely rolled off. Tonally it felt dull to say the least. Enter the world of quality tube preamps! I purchased a set of GE JAN 5654W tubes from here and holy cr@p! So for starters, I had to spread each pin open with a steak knife to fit these new tubes in their respective holders. That means the (6K4 tubes?) stock Russian tubes are using thinner leads. They are cheaper all around! What the new tubes did. Open the high end up and tighten the bass up. Also the mids present buttery and creamier than ever. Dream theatres "The Silent Man" has amazing imaging and these bring that out. They present a very holographic sound stage. Definitely opened the sound stage up! With the upgrade, easily the best sounding Preamp/BT DAC on the market. It will mix in well with the Technics SA-GX490 and ADS 5 band EQ.

Bluetooth 5.0 on this is phenomenal. Cant say anything bad about it at all. Stable, never drops out. Almost CD Quality with Amazon HD. This product keeps getting better.

I have all my CD's on a 128GB flash drive. Everything is 16/1144 CD Quality .flac files. It did read them but stutters. Went back and read specs. Can only read HDD up to 32GB. So I'm figuring that to be the issue. Will update when I try with a smaller USB or Micro SD and update. Other than this. I'm blown away. This truly is an amazing piece!
