I have a pair of 800 D3s. They are powered by a McIntosh 8207 with a McIntosh 160 controler! My room is 20x17! I don’t feel that the D3s are getting enough power! Looking for stereo or mono amp suggestions. I have heard the McIntosh 1.25 and they sounded great but $$$. Any suggestions? Has anyone listened to Michi M8?
