What is the best amplifier for Tannoy Kensington ?

Ralph, since I never heard your M-60s with any Tannoys I shouldn't recommend them. But based on Gizmo's experiences and writings, I'll guess they would be a wonderful match.

Also, I believe the Atma-Sphere amps are among the most musical and satisfying of all our choices - when matched with appropriate speakers. I once owned a pair of MA-1s which were wonderfully musical within volume and musical complexity limitations. Unfortunately my speakers at that time presented impedance and power demands that prevented the best match. I don't imagine any of the Tannoys would have those problems.

Gwng8: Take your amps to the dealer if you can. I would say they would work ok, but you have to make sure...you might wanna bi-amp...your Pass Labs for the mid-highs, and something like a Bryston or Parasound for the bass.

Ignore the last comment, Tannoys are time aligned thorugh the crossover point, this is why they are so coherent. To biamp with different amplifiers with different transfer functions will destroy what these speakers are about.
I own several pars of Tannoys - your Pass Labs will have enough power.

Yes, Tannoys are easy to drive, and don't benefit from being bi-amplified. You are best off just giving it your best shot with the amp.

Agree,
There`s no logical reason/benefit to biamp the Tannoy speaker.
