MAC & VSA Synergy?


I have been interested in trying some Mac gear & was wondering about the synergy between Mac & VSA 4jr's. I listen to rock exclusively. I am looking at the higher powered Mac's that are available in the used market for about $2,000.00

So what other choices are out there besides one of the new digital amps? The Pass amps always get high praise, how are the newer ones? I noticed they have more power.
Fishwater: I just received a new Pass Labs 250.5, driving my 4JR's. I cannot report specific findings yet as I have a lot of breaking in to do on several parts of my system. But, I will post some comments in a few weeks.
