Musical Fidelity and Sonus Grand Piano too bright.

GHunter - there's more to it than what you say. The point not to adjust your room to the equipment (and forget about cables - I never mentioned them) I agree with and am not advocating.
Most importantly, my point is that if you have a crappy room, going around trying to solve its problems (especially in the highs) by replacing numerous pieces of expensive equipment is not the right answer either.
Lastly, taming highs with things like damping, whether curtains or relatively inexpensive retail products, is not snake oil and is backed by simple science.

My point is simply that you have no experience with the equipment in question and are too quick to suggest an overly simple solution to a well-known issue.

I thought it was common knowledge that damping at the first and second reflection points was (nearly) mandatory, unless one has a rather large room. I doubt that that has changed, regardless of equipment. HP, whose room I have been in, has damping at the first and second reflection points ALL the time -- and this is in his main room, with the AGR speakers.
Electronics simply sound brightER in a non-damped room; they WILL sound bright, period, if they ARE bright,unless the partnering electronics have a droop in the treble.
I've used Tube Traps since 1986, as well as RPG reflectors, and I can't imagine any room less than 15' wide not needing reflection at the first (and second!) reflection points. To NOT be doing this is throwing money away: one is simply hearing the room, not the equipment at its best

Ghunter - 99% chance of room problems, the MF piece is fine. Room acoustics are WAY more real than audiophile amp-inherent brightness.

GHunter - thank you for clarifying your response. Yes, I do not have any experience with that equipment. And I have had electronics that sounded really awful.
The poster (tghooper) mentions nothing about his room, so I couldn't know if he has his SF speakers in a gymnasium or an overly-damped 'English Library' with books, fireplace, persian rugs and smoking jacket to boot.
That said, after owning those terrible amplifiers I had (which I won't mention), and having what I considered a good room, I switched to a smoother amp (McIntosh) and it made all the difference in the world.
There are a lot of shades of gray in this hobby.
