Well, I didn't say deeper/flabby bass was all bad.

Modern speakers can sound downright constipated in comparison. But as we've tended to move into smaller rooms and closer to neighbors, less bass is probably more appropriate.
I'm trying out a tube amp and finally had to find my computer's EQ settings (from the solid state settings) and turn the bass back down (but "impressive" bass is still fun, and impressive).

Vintage amps will probably need a good once over to replace old caps and clean switches.
