I would like to share my experience to give op something to think about. I'm not an expert in any way however.
I used to own Studio 60s and Anthem gear. It didn't sound bright to me at all but I did feel it lacked some clarity for my taste in music playback. HT was awesome though.
Then I changed to Focal Electra and found them bright pairing with Anthem gear. I know they weren't based on many many reviews I read, the experts I talked to, both online and in person, including an editor-in-chief from a hi-fi magazine who actually bought the Focal Electra after he reviewed for the magazine.
Someone suggested amplification might be the culprit, so I brought in Bryston 4B SST2 into the system. I'm sure everyone knows Bryston is an excellent amp. And guess what, it got worse. The Bryston resolution plus Focal Electra revealing nature was too much to handle for me.
Then came the Pass Labs pure class A amplification in place of Bryston. My life becomes beautiful again and everyday is like summer! I find my self listening hours and hours everyday and my whole music collection becomes all new all over again.
My take away from this, while it's all about personal preference, more importantly it's also about the synergy with the rest of the system. The higher the resolution your system gets the more vital the synergy becomes. I've been called delusional by all-amp-sound-the-same crowd. But I know I'm right in my case.
I guess you might have bought the speakers by now. Keep us posted!
