whereas i agree that CVs arent VG
	
	
		i wouldnt be rude about it.  they might be good garage speakers or for an outdoor party as they WILL play pretty loud, i suggest better speakers for inside the house.  the bose should only be used as rear channels.  
 
get some PSBs, energy, or magneplanars for music in the house.  50-100 wpc should do the trick for most rooms.  
 
the CVs are headache inducing if listened to for any length of time.  an old sansui quad receiver would probably do nicely with the 501s in the rear and a pair of maggie MMGs with a sub in the front.  
 
for stereo records, just use the sq adjusted so you can JUST barely hear the rear channels and the ambience will be nicely retrieved.  live recordings will come alive this way.
 
enjoy.
