Speaker match for MC275

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.

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.

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.

Verity Finn was a great match on my MC275.

Another vote for the Tannoy Prestige range with the MC275. Will be supremely musical if that is what you are seeking.

I had an MC275 with Turnberrys. Sounded pretty good until a GL KT88 blew. Why not keep the speakers and replace the amp?

Add a Tannoy Prestige Turnberry SE to this list. It is one of the most mesmerising combination with the MC275. Even the Stirling SE is nearly as good.

I would look for Klipschorns....
