Aball, don't jump to conclusions this is only the beginning. "Synergy" I believe may have had a part in this comparison, it wasn't night and day differences. I am going to be able to listen at my place with different speakers and gear. I have ARC Ref300 mono blocks and also the Mac 501's.
The owner of the Mac and EMM equipment, he has a Dart 108 but I don't really understand why he went with a Mac 1000 pre. I am looking foward to hearing his set-up.
Your question regarding SS or TUBE power supply, I preferred the tube but also liked the SS. The speakers were the main issue for me, I actually use to own a pair of these along with prior B&W's top of the line speaker so I know that B&W sound. I have just moved on and found that I am looking for a different sound just like I did from owning the W/P 7's to the Egglestons, hey you never know I might end up with the MAXX 2's for my main system
