The New Synergistic Research Purple Fuses

@jafreeman The SR fuses' high freq are attenuated when inserted the wrong way. I know because I've tried them all both ways. It's not hard to hear. Cymbals sound bad.

Suggestions for Purple/Master fuses?

Pathos InPol Heritage Integrated 

Innuos Zenith MK3 

My DAVE does not take fuses.  

Can anyone tell what the differences would be going from a SR Blue fuse to a SR Purple. I want to replace them in my DAC, Preamp, and Amp.

A friend of mine has had most iterations of the SR range.

His notes:

SR Red Good improvement in resolution, small improvement in soundstage

SR Blue Less improvement in resolution than Red, more improvement in soundstage than Red

SR Orange Good improvement in resolution, good improvement in soundstage

SR Purple Big improvement in resolution, big improvement in soundstage

Would have loved to have heard Frank's view on the SR Master.

Someone whose opinion I valued.
