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! ............

SimAudio W10's work great with Magnepan 3.6's.

Gutsy, good bass, dynamic, transparent...
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!
