Poorly built, minimally functional.

Just awful construction. Numerous cold solder joints, loose components on the board. Intermittent sound of plugs moving, obviously good cables.

Cons
  • Quality

Worth the price but NO documentation.

Preamp received in good condition but there was no documentation. So I had no idea what the technical parameters were. Actually I didn't know what the power supply requirements were or the min/max input and output voltage levels. There is also a small on/off switch labeled "on" in the middle of the circuit board. turn on and off" but it's not a power button! So what does he do? I asked the seller if he could provide technical documentation but he didn't have any so he asked if I would mind…

Pros
  • Amplifier
Cons
  • Not everything is as good as it says
