they are very expensive space heaters. But they are well worth it sonically. By the way when you are running your amp at listening volume where does your needle seem to rest at. I just wonder because running my Dynaudio's the needle runs at about 1/3 unless a really hard bass hits and I know that is a good thing because most likely I never leave class A mode for most of my listening which is one of the reasons these amps sound so full of emotion in the first place.
