SF EXTREMA vs SF Cremona M

Elipsa's vs. Extrema's is a very interesting trade. If you need a speaker with more ability in the bottom end, I would go with the Elipsa's. However, not at any kind of uppricing.
OTOH,some of this would depend on the condition of your Extrema's.
You would be trading a speaker with a better mid and high freq driver for a speaker with a more modern design and as previously stated a little more bottom end drive.
Like Donjr asked, what is it about the Extrema's that makes you so eager to trade....IMHO, they are one of the best speakers that SF made.

Keep the Extremas. You'll definitely regret it if you let go your Extremas. I have owned them for 15 years and they are still as good as any modern designs. I drive them with the Gryphon Mephisto. Preamp is the Burmester 808mk5. I use a pair of Townshend supertweeters as well.

Ken Kessler calls them "stuff which legends are made of"

It seems that more are in favor of the Extremas. I might just be looking for something newer & fresher look. Maybe bec. I've had the Extremas for around a decade already, or maybe the itch to change equipment from time to time just like most audio enthusiast or audiophiles that I meet.....I am kinda set to go for the Elipsa but feeling guilty to let go of the Extremas also grrrrrrr....I plan to play around with the KAV300i and Synthesis Magnum 100 which I can't use with the Extremas though...currently using FPB200 which takes more time to warm up as compared to the 2 integrated amps I mentioned above. Regards to all!!!
