The third of my three units is still working fine, thus the rating of two stars rather than just one, but as a result of first the apparent poor grounding and especially to the poor construction, I can not recommend this unit.

The shoddy construction, poor quality control and weak amp is the reason I will not seek a replacement

I'll give them the benefit of the doubt and call it a defect)- Shoddy construction: knobs are all at different angles to one another, lettering and markings on faceplate are half printed, solder is visible around the rear inputs, etc.- Overall weak amplifier sectionThe capacitor pop is the reason I am returning my unit
