The AMP-2210HT is our go to amp here at the university where I work. We have them in more than a dozen rooms in both 4/8 ohm configurations and 70 volt. The sound is just fine. We only had one issue in a particular situation, a music listening class. The amps will go into standby mode to reduce power. In this music class, the prof would play little clips of music. He would pause to talk about them, then play another short clip. The amp would go into standby mode and would take a second or so to come out of it, thus the first few notes of a clip would be missing. This is not an issue during continuous music playback and it is the only issue we have had reported while using this amp. We like them very much as they have a small rack footprint and they don’t produce a lot of heat.
