Great value and sound.
The Nobsound (Douk) E 6 is a true tube circuit, not a solid state one with a tube thrown in for "flavor" Once it warms up a little, it sounds amazing for the money or even a lot more. To get the most out of it, you need to order the Soviet Russian tubes for it as they are a lot better than the included Chinese ones. They are well known to be quite microphonic. Once I put in the Russian replacements, that problem disappeared. The only other quibble is the output jacks being on the front next to the volume control. They should be on the rear of the chassis along with the inputs but, oh well, a small, if not annoying, thing. Otherwise, this thinks really kick butt with the right tubes in it.The Nobsound (Douk) E 6 is a true tube circuit, not a solid state one with a tube thrown in for "flavor" Once it warms up a little, it sounds amazing for the money or even a lot more.

Prices point highly recommend.
A very good preamplifier for this price. In terms of sound, it is really good, it has only a few shortcomings, the tubes are very sensitive to the microphone effect, one input and one output, a problem with grounding. But despite everything, the sound is great. The designers should revise the design of this preamplifier and produce an improved version, I hope this will happen. Sylvester
