Where do I go from here ? Spectron Musician II


I running Magnepan 3.6's with a Spectron Musician II. This amp puts out good base but the mids and highs are very strained. My question to fellow Goners is where do I go from here? Parasound Halos or what else could help my situation. I really like black finished gear but Parasound is only available in silver. Any relies would be very helpful! ............

I have heard Audiofan's H2O amps and they really are great. But if you want to stay with a reviewed component the latest Stereophile has a review of a Yamaha digital amp ($5K). They liked it a lot, citing so-so imaging as its only real weakness. But attend a live concert and tell me how much imaging you hear.

btw, if I had reviewing skills and were writing a review of what I heard with the H2Os it would be very similar to the Yamaha review. Worth reading.
Thanks kindly for all of the suggestions. I appreciate fellow members who have the knowledge to help too!
Just curious, how long have you had your setup? I recently got a used Musician ( not the II ) to drive speakers with Heil tweeters, which are like electrostatics. Although, so far most CDs sound much better, a few, 5-10 % sounded a little bright or strained like you suggest. But it seems that the more I play those CDs the more clear and detailed they become. I'm thinking that if I go back to the old amp, they might sound muddy now. Just a thought!
