Speaker match for MC275


I have a pair of Martin Logan SL3s hooked up to MC275. I bit the bug again and am thinking of changing out the speakers.

In the running are B&W N802, Acoustic Zen Adagio, Dynaudio Contour S 3.4, and Kef XQ40, in no particular order.

I listen to Classic Rock, Jazz, and Classical. My budget is around 4-4.5K. Any suggestion / help would be greatly appreciated.

I have B&W 804S with my MC275. Very good match, but I often wonder if there is a better match for the 275. One thing I do know, though, is the N802 in your short list would need more power. Maybe 2 MC275 could drive them well, but only one will for sure be too little power.

FWIW, I did audition a pair of ML (can't remember model) and thought my 804S sounded better.
That's a great sounding combination you have there - irrespective of the passage of time. I would refurbish/service the SL3s and retube the 275 - and then do what Horatio says and get a second 275.
Avoid any Dynaudio with that amplifier... it is far too slow, gooey sounding of an amplifier - not enough guts to properly drive a Dynaudio speaker.
