Hi … not really much more I can add. I’ve had the Red fuses in now at least three weeks. The last one went in last week, the internal fuse for the P10.
I can’t really remember now exactly how the SR-20 fuses sounded. My impressions of the Red over the SR-20’s is, blacker back grounds resulting in allowing more detail through, better timbre of instruments, better treble and better bass, more depth and slam.
Overall, definitely a worthwhile improvement over the SR-20’s and not sorry I upgraded.
The benefits were definitely worth the additional expense.
Plus I updated my home cinema amp and processor with the new Red fuses so enjoying similar benefits there.
I had a WA-Quantum fuse attached to my P10 SR-20 internal fuse which got slightly damaged in the transfer tot he Red so currently waiting on a replacement for the chip fuse to arrive.
