I think it's very unlikely that you will hear any difference at all. The combination of DN2540 and VR150 is so effective that you can barely hear the difference between rectifiers. I do think a mesh AZ1 sounds a fraction better than an 80, for instance, but a single VR and CCS are a really good filter.
When I had a CCS with cascaded DN2450 and VR150 combination in my preamp. I was suprised to still be able to hear what I did in front of that. (Caps/choke changes). I was very suprised that I heard a difference. Sorry no log files of the ABX sessions

Not sure what you want to do? Reduce?

Do you mean that the front plate is too thick to install the pot?

What might work is using a wood drill like this: Short Length Spade Bits - Tools - IRWIN TOOLS
of a large enough diameter so that the noble will fit and start drilling from the other side first. Once the "thin bit" of this drill starts showing up on the other side. Drill the hole from the front. I think getting some coolant like oil with alcohol will help.

Ofcourse these wood drill bit aren't made for aluminium but I'm sure it will work. Ofcourse the drill tip will be pretty useless after that. So buy a cheap one.

Or if you know someone who can mill it for you...like a local workshop that does metalwork...they could mill out a little square for you.
