With Macs current speakers and previous models with metal tweeters and mids the tube pre-amps and I just don't get along. Now with Snell A7, Magico S and A series I have no issues with the better tube pre-amps sonically. The limited flexibility and lack of features are my biggest concern. B&W latest speakers don't do well with Mac tube pre-amps either. Any speakers with resonant tweeters or have elevated high ends just don't work well for me and throwing in tube pre-amps just isn't my cup of tea. Now if you are using a MEN220 to tame the high end and smoothing first then I might be ble to accept tube pre-amps if they had the flexbility. Seeing a graphic EQ in the tube pre-amp section of the MA 12000 looks like a big step in the right direction to me.
