I really appreciate this thread as I cannot think of a better way to be introduced to new favorite music. Just a few to mention that seem to get the best out of my 170 original mains is Muddy Waters "folk singer" in HDAD
24/192 and 24/96
For the surround I like the Coldplay Live 2003" and
Celine " All the Way A decade of songs and video"
but like more and more people I meet, my taste for music seems to be all over the place

I am using a HK AVR435, anyone have any opinions on how much better this piece of electronics would sound with the Sierras
I am using a Denon 3910 for my source
340se for center and inwall rears with a Rel Strata III subwoofer
My room is small
