After 2 weeks worth of run in (as things have now stabilised) I feel that I am now in a position to comment on the MOD21 part 1 I performed on my 7510 6/3.
I am gobsmacked by the level of detail retrieval at hand - fine detail is rendered with much, much finer brushstrokes.
And yet this greater detailing is not at the expense of tonal balance - the tonal balance is pretty much the same as it was before effecting the MOD21 stuff.
Rhythmically things are bang on the money too (as they were before).
Low bitrate radio streams sound far more convincing than before - I use the BBC iPlayer plugin on with my Squeezebox SB3 setup, and the listen live on Radio 2 sounds very. very good indeed - you're talking 96 kbs with these streams. Any lower on the bitrate and things sound pretty awful, as one would expect (don't bother with Alien BBC unless you have to).
Recordings that are less than perfectly done benefit too - I played "wind up working in a gas station (Zoot Allures)" by Frank Zappa last night, and the track, which is a bit of a production nightmare (ie trashy and thrashy), was more coherent and together than I have previously heard by quite a large margin.
Of course there are some recordings that are beyond redemption, due in no small part to the "loudness wars" that are currently going on, and these still sound like a bag-o-sh*te, but you cannot blame the messenger for this - after all, you can't polish a turd !
All in all, the first stage MOD21 is the best £1.00 (factoring in the cost of running the soldering iron) I've spent on audio upgrades.
And I've ended up turning down the vdc on my Maplin psu back to 12vdc - on the 13.5 vdc setting I felt that the effect was indeed like pressing the loudness button, whereas I felt that it was required with the 7510 6/3 stock unit.

Are you sure they are about 8mm or are they smaller?
