Shrinking my system

Before you do anything, you need to have a really good look at your new apartment. The buildings can range from new masonary designs to pre-war buildings that were made before TV and radio. You can easily find yourself in a situation where you get up to answer the phone only to find out that its not you phone that's ringing, but your neighbors. lol. Bilding construction will definately be one of the biggest factors in speaker selection.

The Rogue/Triangle coupling is a good, small system.

I would consider Nola Boxers or Merlin TSMs.
You won't be playing very loud music. If you want to play it loudly you may want to try some really good headphones if you can tolerate them. The headphone amp and transducer technology is getting really good these days.

KEF LS50's, plus a pair of small, fast powered subs to fill out the 35-60Hz bottom.

Or the B&W PM1 monitors supplemented by their PV1D subwoofer. I've heard this combination and it is a winner in sound quality, conveying the sense of music, while being compact yet elegant in appearance.

check out devore speakers. Made in Brooklyn. Some are designed with small living spaces in mind.
