Jm Labs Electra 936 help needed.

I own them. It goes without saying that you need to get the room acoustics right. I would carpet the floor as a start.
I had the same problem with harshness and over bright sound using numerous SS amps. Then I finally took a friends advice who told me that I needed tube power amps. He was absolutely correct it was like magic I promise you. Then I got a 6SN7 based preamp and it got even better. I added a critical Cardas interconnect between the preamp and the monoblocks -get golden something I have golden refs a few years old. Finally I used Jena lab all copper braid speaker cables and the system and speakers sound incredible!
AND NO NO NO a tube preamp will not work I repeat a tube pre will not substitute for the tube power amps. You are better off with a SS pre and tubed power I promise.

I agree with Mechans, that the JM Labs magic happens with tubes. It's too bad that the efficiency ratings of some models suggest that they are more tube friendly that they really are. What do you look for in your figure skaters - technical merit or artistic performance?

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.
