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.

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.
