Don’t lump McIntosh in the same group as Rotel. Rotel is a joke compared to McIntosh. Back in the 70’s, the only stores that sold Rotel were those that couldn’t get credit from any of the other companies. Shame on you!
PS Audio BHK lacking..
I bought a used PS Audio BHK preamp to replace my Rotel. It sounds thin with no depth & bass compared to my Rotel so I let it run for over an hour with no change. I'm new to tubes so I'm looking for ideas. New tubes or what?
