As Mr. Burns (and possibly Monty) would say, "thankyou, masked stranger!" I must update it at some stage today too.
In terms of the black modded filter (the small pieces of foam removed) vs the whites; I mentioned earlier that the piano does not quite sound the same. It is not "tonally off" as I put it, rather its presentation is a little more relaxed. Slightly darker perhaps. It still sounds magnificent, of course, however just a tad less striking.
Take for instance the concluding piano passage toward the end of this (hopefully I have the correct track):
Hmmm ok I was starting to wonder too because I found the piano to sound very good, I think the Black mod filter "Grey" ☺️ was a very good idea think it's had a very good effect.....
