With SMc Audio's newer upgrades, they literally only use the chassis and heat sinks and virtually everything else, including the boards, is replaced. Steve has my pair of DNA-1s that he is doing his "everything" upgrades to, including his new Gravity Base System that is supposed to make a substantial improvement. I believe there are currently only a few amplifiers with this particular upgrade and I have read three owner testimonials, which are all very positive. Mine will have new faceplates and should look and sound like substantially different/better amplifiers.
