Manley snapper vs Atma-sphere M60


Trying to figure out the best way to go between these 2 amps.  They'll be lighting up Tannoy Kensingtons.  I play mostly rock on CD's.

Any thoughts/comments......thanks.

Coincident Frankenstein 300B monos unless you like it really loud. Manley if you do and M60 in between

Push pull for rock. I use Manley Neo250, Neo300B SE/PP and Mahi on my Tannoy Kensington. 
Both are quality amplifiers made by reputable companies.  You really need to see if you can get an audition because it will come down to your personal preference.  Nice problem to have.....
You will never get better service than from Ralph Karsten at Atma-sphere, whether you purchase a used pair or buy them new. 
Thanks so far.  I'm really not sure the snappers will outperform the atmaspheres.....overall.
s1nn3r, I have not heard any of your equipment choices, but it is really beautiful looking gear in your listening room.
gwng8, I own Snappers and previously had a different model from AtmaSphere.  I agree that Ralph is one of the best for product support, but I found Manley to be very good as well when I had a problem -- friendly, competent service.

Regarding sonics, I had different speakers and it was years ago for the AtmaSpheres, so not relevant to compare.  Other than the different presentation from an OTL design, another consideration is the Snappers have a fixed output around 5 ohms while AtmaSphere amps typically perform best into loads higher than 8 ohms.  What is the rating for the Kensingtons?

Oh yes, EveAnna Manley often utilizes Tannoys for demos with her electronics and at one time (not sure about current) she matched the Snappers with Tannoys in her personal system.  And she loves R&R!
According to the tannoy manual nominal impedance is 8 ohms, minimum impedance is 5.5 ohms.
The choice of music isn't going to make any difference - the amps and speakers really don't care about that, and there really isn't any way to design an amplifier to play rock better than classical or vice versa.

Now bandwidth of the amplifiers might make a difference. The M-60s are full power down to 2 Hz. This is to prevent phase shift in the bass region, which can in turn cause a loss of bass impact. The Kensington is a benign load for either amp.
Thanks to Ralph for being a real gentleman here.  He replies to simply report relevant information without attempting a big sales push.

That is unlike a dealer commenting over at Speakers who continues to push the OP to come to their store.  If like Ralph, they could simply state what they see as positives in some of the products they sell.  But my sense is they continue to post, using the Forum as a sales tool.
For the Tannoys you may need only the Atma-Sphere S-30. And if you happen to see a used Music Reference RM-10 for sale first, consider it. 35w/ch, 25 if wired for Class A.
When in doubt, call Ralph at Atma-Sphere.
My MA-1's and MP-3 are the cat's meow...
