This is all great information! If I could afford to, I would have two or three different pre-amps (or complete systems) here at one time to really compare.
Although I would never get anything else done ;) I don't have any good dealers near me that cary either brand much less both to try and compare, so I must buy to try. Also I still have my older ARC VT100MKII power amp, which is not bad at all, however I like the Mac 402 better with the Wilson WP6. It may not sound as "warm" in the mids as the ARC but It has gobs of clean power , which translate to better attack, tighter bass, also there seems to be better imaging, and decay on instruments and reverb, etc. I have not had a ARC REF amp in my system yet, and I am sure it would be great, but they are at this time not in the budget. Also I really like the look of the Mac!
