Manley snapper vs Atma-sphere M60

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.
