Thanks to whoever brought this thread back.
The three SR Purple fuses in my system are fully broken in at this point. They replaced three SR Orange fuses that were being used before.
The sound has never been better.
I compared the SR Orange, the SR Purple, and the QSA Yellow fuses in the system. While very good in the detail department, even better than the SR Orange fuses, the QSA Yellow fuses just didn’t have the musicality of the SR Orange and Purple fuses.
If you’re into detail and HiFi, your choice may be the QSA Yellow fuses. For tonal accuracy and overall emotional involvement in the music, the Orange, and especially the SR Purple fuses would be the go-to choice.
