After driving Apogee Duetta Signatures for 15 yrs w/ my MC7200 and C35, I am now faced with the question of where do I go from here? My Apogees are finally buzzing (bad Ribbons). This Combo has put me into Nirvana many times. However, my new quest will more likely be SoundLabs Ultimate 1's W/ The McIntosh MC602 and C200.
