Have any you tweakers used MusiCoat on mods that you have done?
no I haven't but as you may be aware you can get Musicoat from SMC aka: Steve McCormack. Should be able to provide you with more info. if desired.
I agree with Bob B. above. Steve McCormack offers Music Coat treatment as an option on his "Gold" level up-grades, but I only went to Rev. A with my DNA2DX amp, so I didn't get it. But Steve is a believer in it, and says that it makes music sound more "well liquid" (no pun intended). Cheers. Craig.
