Hi Pops, your Mac will work I owned a pair and actually had them paired up with the Andras with my ARC REF3. Then I had a chance to audition the Pass X600.5's again paired up with the ARC REF3 and prefered the sonics over all across the spectrum, no comparison actually. Notice how the ARC REF3 stays, that's a great pce and long term keeper always connected with balanced cables.
Just trying to assist because I've been there and done it already but those new Pass amps weren't out at the time so that's why I mentioned them also. I've heard the comparision in a friends set-up and preferred the new design by a large margine, only down factor is they do run warmer.
So to fast track and save your self some money and time this would be my sugestion;
Andra II's
ARC REF3 pre
Amps
Pass 100 or preferably 160's if you have a larger space and you are done for a very long time.
