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,

bypassing the channel level controls?

I wouldn't. Have you tested your channels individually at your listening seat? I tested mine (250Hz; 500Hz; 1kHz) and discovered that the left channel was off by -3dB from the right. Why? Perhaps my room (asymmetrical, different openings left/right side)? Or tubes? Not sure, but am glad I discovered this. And glad I have the individual channel levels on my Mapletree Audio 2A SE Linestage to correct.

Dag! I wish you hadn't said that. Now my upgrade wheels are churning ... and just when I thought I was finally done!

Can you describe the improvements a little more please?
