Thanks for the response guys. I appreciate your comments very much. I know I have to audition these. I will not spend money on anything until I hear it. Other responses did clear up some other questions I had. I had a feeling the avr600 wouldn't cut it. Thats why I was thinking of going with a dedicated music setup.
I feel I'm willing to go as far as the Avalon eidolon diamond, or the current sasha w/p. I feel the sophia 3 wasn't as fast in response as the w/p.
I have a local Avalon dealer. The only problem is that he works out of his house. So auditions are done by appointment only. He had a set of Avalon Ascendents in the room, but they were not hooked up. I did however listen to the Magico V3's with a Jeff Rowland Preamp, VAC phi 300.1 tube amp, and MSB cd IV transport. It was a pretty good setup I have to admit. The Magico's just didn't do anything for me. For such a large speaker I was unimpressed with the lack luster base. Transparency and sound stage was very good though. Just overall it didn't win my heart or anything. That speaker goes for $27k+
"Avguy" I will have to agree with you about the analytical sound. I noticed that it can sound a bit metalic in some situations. It doesn't necessarily sound bad, but rather a prefered taste. I don't mind a bit of a forward sounding speaker. I noticed the wilsons are like that at times, as well my paradigm's actually. I noticed they can sound just a little bright at times, and I do mean little. It isn't ever to the point of being intolerable though. Just natural characteristic of the speaker. Its hard finding a speaker that is very natural sounding with superb imaging without getting a little bright.
If I were to predict which I would like better, I think I would probably like the Avalons a little more on the music side. If I were to upgrade my 5ch though, the Wilson's might be the way to go. Wilson's also have center channels which is a plus, and the speakers are really efficient so my avr600 will have no troubles. If I go seperates for my dedicated music setup, I'll look into Jeff Rowland, Simaudio, or Ayre. I love Boulder, but its too rich for my blood. As for cables, I'm currently using a bi-amp pair of Analysis-plus oval 12 for my 60's. Another company I've been wanting to try is xlo electric. If xlo is good enough I would use that for a dedicated 2ch setup. I really don't believe in cables that overall tune the way a system sounds. I really do prefer a cable that has no sonic signature at all. The two companies xlo, and analysis are known for that. I do not like nordost, mit, or transparent audio. They have a sonic characteristic that is unatural to the source in my opinion. Thanks guys keep it up!
