Harbeth Compact 7-ES3 Speakers

bet = get

Q: What happens when you play a Country and Western record backwards?

A: You bet back your wife, your dog, and your pickup.

I think your room is too square and too small to use a subwoofer. I ran a pair of Compact 7's in an 11 X 11 room for a while (not by choice) and there was barely enough space for them. Yours at 12 X 14 should be fine, but borderline. I would sell the sub and dump the money back into upgrades elsewhere or buy some music. The Compact 7 will be an "upgrade" over just about any other speaker I can name so, yes, I would replace the Katan's. You may also want to consider a pair of Monitor 30's for a room that size, which have a smaller box and slightly less bass output.

I like my music moderate-to-loud

FWIW - Harbeth are great but the Compact 7-ES3 is not the kind of speaker for loud dynamic sound.

In your room, if your Linn is any good, (pardon), if the the amp mates well with the harbeths, you probably won't need the subwoofer. ( I thought you bought the P3's?)

I think you should listen to some Country and Western, you may like it.
