Ooh, "SVT Killer", that's fighting talk!
Hartley Peavey says something similar in one of his White Papers. Apparently when Peavey developed their DDT system, they found that if it was set up to remove all clipping, it made musical instrument amps sound too dull. They had to slow down the response time of the DDT circuit to let the power amp clip heavily on attacks.
My own experiments bear that out too.
