I've had stock McCormack DNA amps, and ones modded by SMc Audio. As great as the stock amps are -- and they are plenty great -- the modded versions are right out of this world. Be advised, "Rev B" and the better "Rev A" were the terms that Steve McCormack's company used to use. He has since changed the nomenclature, using "Gold" and "platinum" and the like, I believe.
Also, you'll not find a better company to deal with. No affiliation -- just a very happy customer.
