speakers for low listening levels/tube amp


I just bought a tube amp (a sophia baby) and am looking for speakers that match well. I listen to lots of acoustic music, some jazz and bossa nova and occasionally some heavier music like rush/pink floyd etc. Huge bass is not a big deal for me.

I'm most interested in speakers that sound rich and detailed at low volumes. Having 2 small children and living in a townhome, I listen a lot late at night and want a good soundstage without lots of volume.

I've considered Omega and the Cain abbys (the Cains look great but are a bit spendy for me). I also looked at Klipsch (RB35 and RB75). I'd like to spend in the range of $600, but could go higher. Of course lower is better and leaves more money for music.

Does anyone have any advice? Never having heard these and not having time to demo, I'll be buying blind so to speak.

Thanks!

I would look at the cheap, floorstanding Quad dynamic speakers, used Spendors, and used or cheaper Proac. These sound good for the money and are compatible with tube gear.
Try Triangle Cometes or Proac tablette ref 8s both are good at what you want......Triangle being more lively of the 2.
I started out with a pair of Carolina Audio JTM's.
This after having Dynaudio 1.8MK II's.
The JTM could be played at 70db's and offer a full
dynamic and lively sound even at that low a volume level.
The can be placed flat up against a wall also.
The don't need a lot of room or high power amps.
