I have a bit more info from Stereophile:
They say someone with solid state amps with input impedance of under 10k ohms this will not be a good match (see below) but my Pass Labs X350.5 has a 20k ohm impedance.
So it is double what they say I should avoid so this makes me think I am ok but just not sure. I am hoping someone much smarter than I with much more experience and knowledge can chime in and help me. I thought this info helpful and wanted to share. I know I can be safe and stay away but its a local sale and a decent deal so I wanted to turn to you guys/gals! Thanks
Stereophile:
This graph was taken into the kind 100k ohms load. Reducing the load to 10k ohms, a typical input impedance for many solid-state power amplifiers (fig.5), increased the second harmonic almost tenfold, to -60dB (0.1%), and added some third harmonic. Dropping the load to the admittedly punishing 600 ohms raised the second harmonic to -44dB (0.6%, not shown). It is probably inadvisable to use the Hovland with those few power amplifiers that have input impedances below 10k ohms.
