Mapletree Ultra 4A SE - mods

Any thoughts on replacing the stock PS to preamp umbilical cable with a better one? Revelation Audio's product (silver wire) is well known to improve the Mapletree's sound, but my DIY instincts are strong. Has anyone tried to used different wires and what was the end result? BTW, what is a good source for teflon shielded cryo silver wire?

2nd mod, how about bypassing the channel level controls? Don't need them nor use them. Easy mod to implement and reverse. Wondering if the sound would improve by removing this pot from the signal path.

Regards,
