Besides Spectral, what else do I try........

Mike, spoken like a true salesperson! I hope I am a very small minority (would not be the first time) to think that they (at least from photos) are some of the worst examlples of industrial design ever seen. There is such a thing as taste. There is such a thing as quality industrial design. I think that Edge fails on both count. Wish you well with the line.

I think you should also consider the Linn Klimax series preamp and amps if speed and clarity are important to you.

I use a CTC Blowtorch preamp and one of the NEW Rowland 300 series amps. I've stressed "new" because I've owned Rowland in the past. The 302 I own is in another league from what came before. This combination is superb. Good luck in your search.

Have you considered Jeff Rowland equipment? Based on the above, it seems you are getting many opinions from many people. I strongly suggest you borrow several units and try them out with your Naim CD player and Audio Physic Virgo II's. This is the only way you are going to really know what you like. cheers..

Gee, my recollection of Spectral and Rowland gear is that they were quite different. Sonically I can imagine them being very compatible, but different never the less.
