What does a Hexfred do?


I've seen some threads here, as well as some advertisements touting the benefits of Hexfred diodes in the power supply. Upscale Audio seems to think they're useful in the power supply of the Cary SLI 80. I'm always contemplating tweaks for my Cary V12, so I thought I'd ask: What do Hexfreds do, is there any sonic benefit, and if so, what is it?

Thanks!

Is this why my ARC CL-60 always had a nasty "buzzsaw" ghost riding the waveform of vocals? It has tube output stage but solid-state rectifier.

It was either this, a Classe DAC (solid-state) or digital jitter (maybe all three?)
that just drove me up the wall.

I hear it from time-to-time with my current system but to a much lesser degree.

Can't the demons just leave me alone???
