Thanks, I did find the section in the manual that instructs to leave it on. It does run warm, and I replaced the acrylic top with the metal one, should be a better conductor. Otherwise, this is an major upgrade from my DMC 12, no slouch in imaging and clarity. Hoping that Spectral will get back in the phono business again.

Recently purchased this pre amp from a fellow audiogoner. This is replacing a DMC 12, which is usually left in the powered on state. Is the DMC 30 unit meant to be left on, or powered off when not in use. I could not ascertain from the owners manual. The power switch is on the back next to the line cord, fairly incovenient.
