Suggest Speakers for Peachtree Nova

The most obvious and quite good would be ERA Designs.
ERA Design 5 or 4.

There are lots of good choices, probaby too many to list:

Monitors - ERA (as mentioned by Muzikat), Linn Kan/Tukan, Rega R1, Triangle, Von Schweikert VR-1 (my personal choice)... almost any good monitor > 87db efficiency will do, depending on how loudly you need to play. That's probebly not a big problem in your room.

If you choose carefully you could also use some floorstanding speakers. I have tried a pair of Klipsch KG4s w/ a Peachtree Decco and Dave Brubeck sounded pretty good!

Another floorstander to consider along with monitors (no separate stands needed) is the OHm Acoustics Micro Walsh tall (MWT).

check out the castle harlechs on agon...a little over your budget, but they will hold their own with any 5k speaker i can think of, and the build quality is superb. easy to drive..not fussy...a classic.

i vote with br3098--for a 50w amp in a smallish room the von schweikerts or regas are a good choice, with the von schweikert being essentially full-range, while at $300 or so used the regas are especially good value. if you wanted to step up, the paradigm signatures s2 are really outstanding--some dealer is listing a new pair on agon for $1295 ($2400 srp. i haven't heard jaybo's castles--i should check 'em out, since jaybo's usually spot on.
