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

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

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.

Really happy with the sound and build Got 3 in one unit Can even use the usb for charging or led lights when its in rca setting Double thums upp

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