JM Lab Electra CC900 or CC901 for 926 and SR900

Fronts: Electra 926
Rear: Electra SR900

Cener: CC900 or CC901???

Is CC900 perfect fit or worth spending extra $$ for CC901

why? or why not?
I have the 901. It is a better center. Voices just sound more natural. With the 900 it just sounded boxy. I run it full range and it sounds great. BTY that is a nice setup. I have the 927Be fronts, cc-901 center, SW900 sub with old polk surrounds.
Go with the 901 since you have the 926's for the fronts. The 900 as I understand it was designed more for the bookshelf models of 906 and 907be.
