Amp recommendation for Vandersteen Treo CT

Decided to go with Luxman L-505uXII for now. If I don't like it, you will see them in Audiogon in couple of months from now. My long term plan is to go with M-900u for my Dynaudio Confidence Platinum C4 and try the PS audio BHK monoblock for the Vandy's. I wish at some point, I can upgrade my Vandy's to Quatro Wood CT.

If Vandersteen goes out of his way at his seminar gatherings to suggest great performance can be had with zero or lowest feedback type design amps.Just wondering what was the driving reason behind your choices above?

@audioconnection  - Cost was one of the choice. I tried Luxman L-509x was really good and I want to see how the lower end of Luxman would perform. What would be your suggestion? Just curious.

Triple A: Ayre, ARC, or Aesthetix

The dealer I bought my Vandersteen suggested Aesthetic Mimas. He had one but then he sold the last one. I looked into Ayre and ARC. I was not able to find Ayre in my budget and found ARC Integrated AMP this week at Audiogon but then I already ordered Luxman L-505UX Mark 2  over the weekend. Just plugged it in this afternoon. Here is my take so far. It is definitely sounds and feels like Luxman. Bass is good but not as much as L-509X. I think it needs to be broken-in.
