If it were me I would set it up and have a listen. Use it as a free home demo then return for refund. If the sound us to your liking then look for another or for a 360. If you don't like it then look for something else. I woukd not keep a non mint unit described as mint.Got the Hegel H300. Packaged well but contrary to the description of mint, there is an obvious and deep scratch on the volume knob. What's worse is that the knob is out of alignment, because it rubs against the housing when turning, the cause of the scratch.
I have yet to test out the amp, but am a little disappointed at the inaccurate description and am concerned about the root cause of the knob misalignment, I have a feeling it was mishandled (lifted up by the knob) at some point.
The seller is cooperative and offered a full refund. I wanted to test out the amp and get your opinions before shipping it back.
