We used $1.06 Cree SiC rectifiers in a power supply for a tubed preamp recently and they sounded much worse than hexfreds. The SiC's had a funky, weird quality in the high end that made the system almost unlistenable.

You must not put them in series with your speakers, only way you can "listen" to them.

If switching PSU rectifiers from Si to some other very close performing (at line frequencies) types (such as SiC, just compare datasheets and curves) makes your preamplifier "unlistenable" then you PSU really needs some serious redesigning

Unless the main effect is placebo effect, of course

I always think about Creek's silicon carbide diode for my amp, but their price tag just is way too high.
