you said a mouthful
I’ve fought the rock issue of brightness since I had Thiel Speakers ,very revealing , and metal tweeters
The more revealing your speakers with all solid state, especially , the rock becomes tough to accept.
You have a “wow” setup ,with the focal evo’s, especially revealing
Anyway, I’m especially happy now with tonal balance for old rock.
my top rock album brightness reducers:
1) run Roon and convert to DSD files,vs pcm
2) went to CJ ET3 preamp ,and rolled tube
3) Used pre to amp IC to Cardas Parsec
4)Adjust sub woofer to BBC bump at 100 hz with 6-9 db bump (100-250 hz warms up tonal balance - can do in Roon esp)
good luck
