Manley Snapper vs Neo-Classic 250


I'm wondering if anyone has any opinions/experience/thoughts on the sound differences between these 2 amps.

^ I have a long list to par down:
Dynaudio
Monitor Audio
Reference 3A
PSB
PMC
Epos
Elac
Accoustic Energy
Living Voice
Tannoy
I've also always liked MBL...but pricey


I'll check on the extra cost to add the triode switch to the Snappers....might help close the price gap
The cost to add the dual switch to the snapper is $300...so that is a nice option to have. How much heat do either of these amps put off? Would putting either one on a shelf with about 16" of clearance to the one above be an issue?
What sort of heat do these things throw off? Could they handle being on the bottom shelf of something similar to this?

They would have around 16" of clearance (between them & shelf above).
