Amp recommendation for Vandersteen Treo CT

Thanks for the response. I'm looking for Integrated Amp since this is for my living room.

My apologies for no looking at the Simaudio unit first.  I just assumed .  Silly of me.  The Musical Fidelity M6si is spot on what you are looking for then.  Price is exactly $2999, 220w and circuitry that should sound really good with your Treo CTs.

Although a hair above your budge, you might want to look at the Rogue Pharoah as well.  Awesome integrated and if you find one used would be below budget.  It is a class D and the tube input stage is there just to tame the brightness a touch.  I have the Hydra, which is the 100w power amp.  It would also be a good fit, especially if you were to roll in a pair of NOS Cifte tubes.

I use either Atmasphere MA-1’s or Ayre MX-R’s with my Treo’s.
Unfortunately, both are out of your price range, and, not integrated.
An Ayre AX-7e might have enough power, but it would be pushing it.
I would give Ayre a call. Ayre is a great combo with Vandy.
Where are you located?

I heard the Ayre AX-7e driving the Vienna Acoustics Liszt without breaking a sweat.  Then they put on the AX-5 (not Twenty) and of course it was better.  Stacked Belles Aria preamp and stereo amp are no larger than a Luxman integrated.

What happened to your Luxman 509X integrated amp? Why are you getting rid of it? Your Luxman 509X is a very refined integrated amp. Did it break? I would think that your Luxman 509X will be superior sounding to the above integrateds that were suggested or recommended. I don't see a point why you want to get rid of your Luxman 509X and get a cheaper one. Did it not sound good on your Vandy Treo CT speakers? 

What front end source component(s) do you have?
