They need to be biwired for starters. Be sure you have the 12 pg setup book and use pink noise for set up not 1K but a wide band 100hz to 1k When correct the ball of noise will knock you over. USE Tubes. Ive have Great results with ROGUE 120 monos. Fast transient and powerful controled bass. Not as lush as the cary but you might be suprized how fantastic they sound. Ive used Cary, Hurricanes, VTL 300's Rogue 120's now I have the zeus by rogue. Id say after using all of those to give the Rogue 120 monos a try.
