Douk Audio P6 Tube Preamp Home Audio Preamplifier Mini Valve Pre Amp with Bluetooth Bass and Treble Tone Controls for HiFi Stereo Active Speakers with RCA USB Input

Lovely preamp. I swapped out the valves for some stone age ones I found at a decent price. It will take a pretty wide range of commonly found valves. Build quality is nice, solid enough with decent knobs and switches which function pretty positively and I've not lost where I am with them yet. Straight forward connections at the back, very easy to set up, compatible with anything that has RCA inputs. And Bluetooth! I forgot about that as I don't use it, but there is a switch to swap between inputs so you're not going to get your comedy neighbour jumping onto the open BT reciever at random times. I did buy a heat sink to use with it just to keep the heat down a bit. It takes a short while to warm up properly, but it colours the music just nicely and to my ear helps to add width to the sound stage. This is quite genuinely my favourite purchase in a long time. One day I'm sure I'll have saved up enough to upgrade, but that upgrade will still be made by Douk!

Bought it to go with a cheap briefcase record player and an old Denon amp. Sound quality is soo much better and having Bluetooth built in means my old system lives just that little bit longer.

better than expected, doing a great job.

This small package does a good job to give you a warmer sound. I did buy the improved valves they recommended and have not tried the originals. They will do as spares. The controls are nice with bass and treble controls adding nice tones. The input for the stick might be ok for low quality mp3's but high quality ones stutter.

Nice little Preamp, I have it connected between a Douk q11 DAC and a Douk A5 amplifier, probably a little overkill kill but all in all it gives a lovely warm sound.

Good buy and good quality valves

Controls have a good feel,multiple inputs a very versatile compact unit.
