One of the Reasons the Rogue Preamps sound so nice.Seperate power helps keep everything in place.
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?
