I have the full Studio .v4 Lineup.... 100's, CC-690, 20's, and single ADP powered by Rotel 200 x 5... Phenomenal, to say the least... Anyone who comes to my house is truly astounded with the sound quality, and blown away by the HT experience...
Everytime I fire it up, they still put a smile on my face... Can't say enough good stuff about them.. Make sure you power them well, if you listen to them loud.. Receiver will drive them fine, but at ref. levels, the extra power is demanded.
Good Luck
