I'd suggest a BBC monitor (they come in various sizes and prices) from Spendor or Harbeth. Not fatiguing, lovely tone. If you want big scale music to sound big scale then add a subwoofer ... REL (I own) or ACI seem to be the frontrunners. In my experience large scale orchestral works and live performances featuring acoustic guitars played through a PA system are lacking without those low low frequencies. They come to life with a sub. However, since the sub costs at least $1000 and would make little or no difference to small ensemble music it might not be justifiable for you. If you have a difficult room then monitors and a sub might be better than full range main speakers since you can place the monitors for good soundstage and the sub for deep bass without boom.
By the way I also own a pair of Spicas ... you would probably like the sound of Spica angelus or TC50s if you can find a pair .... they're an absolute bargain. Unfortunately the angelus looks very wierd so if your listening room needs to also look attractive then that option is probably out. (My wife banished my hifi to the spare room !) At least our 5 cats can't get in to destroy the speakers.
