M900U vs the world


So from all my reading it seems this the amp to have at around $15k or less. Any other amp to consider over it at this price point?

You know, another amp in this price range I really like is the Vandersteen amps.

I haven't heard them for very long, and I did not get to hear them full range, but for the 20 minutes I got to they were really nice.
Mac is in my audio rearview mirror. The Model 16 and my Motherlode will suffice beautifully for the foreseeable future! At least that is what I stated to my wife.
Heard the M900U for 2 weeks straight every day in a buddy's system in Toronto, I think he bought it for 18K CAD.

Not overly impressed for the $, but my buddy is/was - and if the guy who owns the gear loves it, nothing else matters.

Prefer Pass and CODA personally for that kinda money.
Kairo what did the rest of his system look like? Maybe he likes the synergy? What did you find lacking ? Low end? Dynamics? Too polite?
