Budget Strategies forTightening up Bass?

See the 'nearfield listening' thread over in speakers.
Vibrapods implicated in bass issue. For better or worse?

BOB: My understanding is that Alan Yun designs his speakers with tube amplification in mind. At least I've read that somewhere-- that's not a direct quote from him.
As for the room, it's an "open plan", so the livingroom where speakers are located is separated by a half-height wall from adjacent diningroom and open to adjacent two-story entry. A pretty large space.
MICHAEL:I will look into the sub option. As for reinforcing the floor, it's hardwood, suspended. I can't see covering that with plywood.
MAGFAN: I suspect Vibrapods are not the best footer in my case-- I plan to try alternatives.

Bob-- Thanks. Interesting point, which I'll keep in mind. For now, my goal is to see what can be done with the current set-up. If nothing works, then I'll certainly consider changing speakers or amp.
