My room is rather large,but the speakers are up to the task.
Some sidewall treatment and some ASC tube traps,so the room is not too dead.
Power to all gear is from dedicated lines, amps on a separate line.
Furutech products have been a real improvement opening up the amps.As are upgraded fuses( Iso Cleans,HiFi, AMR)
The speaker/amps maybe old but they have been modded and to my ears(compared to other systems I've used in this room)they are on par with systems costing much more than I can afford.
The Lightspeed Attenuator is great also in the clarity dept.
