I listened to an S-500 upgraded to a 550e, and found it to have a dead, airless, lifeless sound, especially the high end. Perhaps this unit was not representative, I don't know, because the S550e certainly had high ratings.
The heat sinks were very slightly warm on this unit. Does your S300 run cool like that? I think you should try some more current amps, like the Simaudio, McCormack, etc. If this is from a dealer, I would make comparisons with this other equipment.
