I've been looking at the ARC REF3 as a possible replacement for my Pass Labs X 0.2 preamp. After reading the Stereophile article on the MAC 1000 at their website and reading the answers on this thread, I'll be looking at the MAC 1000 as well, which is one drop dead gorgeous preamp. It looks like there's a new kid on the block. Also, I agree with Audphile1: Gpgr4blu, your comparison and contrast of the two preamps was very well written and thoughtful. Best Regards, Stan
