Less bass is not necessarily a bad thing. Lesser quality bass is. Most tube designs do not have the bass impact of similarly priced SS amps. Heft/weight/slam are a few terms used to describe bass impact while definition/articulation and tuneful might be used to describe quality. Even fervent monitor disciples like bass, but what draws so many to the monitor is the waist-up (midrange to treble) purity and coherence. Quality bass and deep bass in one package is very expensive. If you can't afford the package then honestly decide which you prefer and aim for that mark. Also try fidgeting with speaker placement again; their sound has changed due to the amp replacement and so, perhaps, should their position.
Help learn diff.between SS and Tube
I am auditioning an Anthem Amp 2 (a Hybrid amp) and it will be a change from my SS Marantz MA 500s in a bi-amp config. I have not had the Anthem more than a few hours (the amp is broke in) and I think right off the bat the Anthem seems to have less bass than my SS. The bass seems to be there, my room shakes, but its not as something, I can't put my finger on it, less "punchy?" Can someone pleez tell me the differences typical of tube and ss amps. Thanks. m-
