I just find it runs very hot. Do you find it hot to the touch? It is not as hot as my Krell amplifier, but still hot. Sound is amazing. I don't know how anyone can listen to CDs after listening to SACD. The improvement is incredible. CD is very good but SACD is in another league. At least on the few SACDs I have. Vinyl is still as good as SACD but different. It depends on the recording. I wonder how anything can get much better.
