If there is one thing you could change in your current system. What would it be?

I would put it in a bigger room. I think I'd like to try a different style of speakers.  Meaning 3 way without a sub versus my two ways with a sub, soft dome tweeter versus hard dome, or even horns.  I also think I'd like to try out SET  versus my current push-pull, and I use to have monoblocks and I think I'd rather go back to those.

. . . I would also put a TT in as the primary front end.  (Even though, all totaled, that is way more than one change I'd make.)  So if I was only allowed one change, it would be the room.
