Bigwavedave, you didn't make any mention of your preamp or your source, but I'd say it is the room. Being a former Focal JMlab dealer, I can't say I found the top end bright on these. The top end is fairly revealing though. If anything, if memory serves me correctly, I'd say your old Electra 920.1 speakers were brighter than the Electra 936. You're definitely hearing the result of a different room. Mechans has some good suggestions. Good luck.
Jm Labs Electra 936 help needed.
I purchased these recently and can't get them to sound right in my room. My room has a concrete floor with Pergo on top. Amp is an McCormack dna1 revision A with Acoustic Zen Satori speaker cable. Treble sounds nothing like the Electra 920.1 I owned a long time ago in a carpeted room. Sounds too bright; room is approximately 600 sq. ft., not sure if I can fix with speaker cables, I am looking for suggestions from people who have had this line in the past.
