Terry worked on my Mc250. I didn't have him mod anything. I'm not a stock nazi, but I don't have a problem with the way the Mac's are set up with the rca inputs and terminal strips. And my power conditioner acts as my on/off switch. I know that Terry has an issue working on units that others have modified, but I don't know his stance on making the mods himself. I just asked him to give it the once over and replace any components that need replacing and he got it back to me in like new condition and it sounds amazing. Can't go wrong with Terry.
