Comments about Nady (SPA-850) 850W Power Amplifier:
i am using 2 chained emulators for guitar and it runs to my 400watt carvin 4 x 12 cab and my 3way 400watt monitor. VERY LOUD even in a 20 x 20 room with drums, bass, and vocals... and we play METAL..
i never turn it up past 5 or 6 to get the volume i need.

it won't power my 901s nor my klh my old out of date 60w fish has more power. sounds like an old fashion hand held transistor radio when hooked to some cheap speskers that they managed to meekly power. i even bridged it and what a disappointment
