Hi @johnc5 -- happy to weigh in a bit. I did a couple reviews of Fritz's speakers. I have a preamp very very close to the Dehavilland Ultraverve III tube preamp (great score) and also have 2 Rythmik F-12 subwoofers and a third sub, a REL R-328.
I had both the Carrera and the Rev7 mk 2 SE in my possession for a number of months, and ultimately went with towers, but were I to choose a standmount, I'd go with the REV 7. Why? I could not tame the Be tweeter on a similar standmount (the Salk SS6M) and I remember the absolute ease and lusciousness of the Rev7. I believe it is an extraordinary speaker, easy to drive, capable of both clarity and mellow musicality. If I was going with Fritz, I'd go with that one.
