Experience with FREDs in a tube amp PS

I'm wondering if anyone in here has installed Fast Recovery Epitaxial Diodes in a tube amp's power supply(specifically- built a full-wave bridge). If so- What differences did you notice? PLEASE NOTE: If you haven't tried it, PLEASE DON'T respond. I'm not asking for opinions; only experiences. Thanx!

OH(BTW)- No soft-start. I can tell by what my lights do when I turn the amps on.

FREDs and Schottky diodes will mostly clean up the treble.
If you are looking for more transparency and dynamics, I suggest that you upgrade the amplifier coupling caps.

A few suggestions:
Low cost: Auricaps & Hovland
Medium cost: Mundorf Silver/oil
Expensive but the best IME: V caps TFT by VH Audio.

I've got Aeon polypropylene coupling caps in my mains now which will do for the time being. I'm focusing mainly on power supply upgrades for the woofer and main amps right now. Overall system dynamics and speed are what I'm after.
