well i will just put it this way about about this whole thing, take almost any home amp and tell me if you have enough current to power an MRI machine. I would highly doubt it, also how many will give you over 7,000 watts per channel at a half an ohm constantly. And even getting away from the beast of an amp that a 10,000 is, if pro amps have small power supplies how is it they can deliever massive amounts of wattage and current. Lately the answer is a switching supply but before it was just a huge transformer. I will challenge home amps against a macro tech 5000 and see what the winner would be when it comes to longer term high power conditions and which one delivers more current. lets see how many home amps can drive my double 18 boxes to there limit without going to hell.

as for dynamics, i do a lot of live music with a huge amount of dynamics so i dont see where the lack of dynamics is in live music.
