Wow! The builder of the amps in question answers! I love this place! Thanks Steve. I like my music loud when the family will let me so I'll either go with the DNA-1 or 225. I do however have another question. I listen to mostly audience and some soundboard live recordings of bands like the Grateful Dead and Widespread Panic (they allow taping and trading of their live shows) where the quality of the recordings isn't always that great. I have heard that the McCormack amps are extremely detailed and revealing. Will this make the live recordings sound even worse? Are the older or newer versions better for this type of music? thanks a ton.
