I had the SF Cremona Auditor M's for several years and comparing to the original Auditors, far more detailed and very highly resolving. At $6K with stands, still a great "under the radar" performer IMO. I too had the upgrade bug 2 or 3 years ago, auditioned most of the speakers mentioned above and at the time had a good friend that happened to be a Magico dealer. I've been in metalworking my entire career and Magico was one of our customers here in Silicon Valley.....I REALLY wanted to like them and auditioned several times and could never warm up to them...just to strident and clinical for my tastes regardless what was driving them. I ended up with Guarneri Evolutions and they best in every way the Cremona Auditor M's as they should for nearly four times the cost. I can tell you both the Cremona Auditor M's and the GE crave good clean power. I'm running McIntosh MC601 monoblocks and both of those models really opened up with that power. They are highly resolving but require attention to details to bring it out...neutral cabling plus I have all gear on 3" maple, Symposium Platforms and a combo of Stillpoints or Rollerblocks. My room is only 16 x 12 and have the GE's paired with two REL G-2's....
I noticed you mentioned the Auditors weren't as resolving as you'd like, but having heard Franco's original GH....as beautiful and full as they are they are not highly resolving in any way. You Cremona's, while not as full and lush will be more highly resolving than the GH's. Have fun and enjoy the search!
