Musical Fidelity and Sonus Grand Piano too bright.

Recently I solved this problem with similar components...MF electronics and Spendor speakers...my problem ended up being isolation. I tried Vibrapod's cheapest pad and it took the edge right off. Prior I was switching from CD to Vinyl just to stay listening, but I can easily go all night on digital now. Just a thought...

In addition to (NOT instead of) isolation, you MAY (or may not) want to try the Dakiom Feedback Stabilizers. For me, an EXCELLENT tweak, at least with my previous speakers (Paradigm Studio 100 V3's). With the Paradigms, these gave BOTH more detail AND more smoothness on the high end, PLUS the bass was noticably deeper and tighter.

{{{{{ NOTE: I haven't had the time to A/B the Intuitive Design Summits with and without them, so I've left them in place since the get-go with the Summits, and the system sounds astonishingly wonderful beyond all possible belief (although that's mostly due to the Summits, the Dodson, and the Odyssey Extreme monoblock amps and preamps).}}}}}

Another great thing I found: The Dodson 217 Mark II D DAC. Phenomenal improvement. Even more so than the Dakioms, I'm pretty sure, but also WAAAYYY more money (but worth every penny). The 218 is said to be even better.

Don't give up. I had the same problem with my old system and it's.....GONE!

Try new speaker cables like the Transparent Music Wave Plus (current MM version or previous version). The MF electronics are a little bright and the Synergistics may be highlighting the issue. The Synergistics are good cables, just not the right match for the MF amp.

If the speakers can be bi-wired and you are using the stock copper plates between the tweeter and woofer inputs, try using better jumper cables between the inputs. Transparent also make some good ones.

Chadlesko has a good point about isolation. The heavy gauge aluminum chassis of the MF has a high resonance frequency that could make the highs brighter. Using the Audioquest Sorbothane feet or the Black Diamond Racing Cones could help.

I've heard the Grand Pianos with an Audio Research 100.2 and Transparent cabling and liked it very well indeed. The MF electronics are probably not ideally matched to the treble of the speakers.

I agree - the MF 308 is on the bright side. Newer MF is a little darker and doesn't have that bightness anymore. I have never heard a pair of SF speakers sound bright so I don't think they are the problem. I would suggest trying a McIntosh MA6500. Arthur
