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.

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...
