Im building an amplifier using ICE power 500ASP+500A preamplified with a Nutube B1. I was thinking on having all in the same case, would this impact negatively?
That ICE module is a combination power amp and SMPS, there is no transformer.
But I do agree, this is what integrated amps, stereo receivers have been for decades. In pro audio, we have instrument amps with preamp and ICE power amp in one unit.
