Seperate Power Supply and Preamps


Several of the top end tube preamps like Hovland, Joule Electra, Herron, and Lamm have no seperate power supply. Others like First Sound Presence, Atma-sphere, Cary, have seperated out the power supplys with some of their models. What are the advantages of this sonically or is this just a physical limitation problem with the manufacturer?

As for the above post: Most companies should provide a RFI filter at the incoming connecting cable side or in the cable itself. Secondly as far as cost is concerned, I think isolating all the nasties that can come from pwr supplies should give piece of mind when it comes to your gear and the money invested. Just my opinion.
