do you mean QSA Black/Rec? There is no Red/Black.
Deciphering Audiophile fuses was frustrating, especially since QSA prices got very steep in a hurry. So I was leaning towards the lower cost Swiss Digital Fuse Box. But your positive review of the new SR Master fuse vs your QSA makes the SR fuse a viable economical choice. Thanks for sharing.
Still debating of Furutech GTX outlets vs QSA steep prices. Also, still trying to grasp if QSA jitter plugs should be on my radar.
