Recommendations for a new integrated amp for Vandersteen 3a speakers


I acquired some Vandersteen 3a speakers a few months back to replace my Theil CS1s and would like to update my system to accommodate them. The recommended power range from the mfg is 100-200 wpc.
I have been using my old Adcom GFP-555II preamp and NAD 2100 amp and would like to upgrade with a new or used integrated amp to replace them. I have been considering:
Wyred 4 Sound sti-1000 or sti-500
Musical Fidelity M6i
Rogue Audio Cronus Magnum or Pharaoh
Odyssey Stratos (keep the preamp)
Vincent Audio SV-237
Unison Unico
Peachtree Nova 220 se
My budget is $1500 for this upgrade. 
Please help me narrow the list or add some other options to consider to upgrade the system!

I wouldn’t argue with John, however I would recommend an older Ayre unit for the Vandersteens.... ( even if the Ayre is not in great shape, Ayre can make it so) 
... HAD A SENIOR MOMENT in listing the McIntosh amp: correctly, it is a MC-2105. Sorry about that...
For that $1500 price check out the Cambridge Audio Azur 851A or the Arcam SA20. The Arcam is rated at 90wpc not any difference for your 100wpc requirement.
I would vote for the Musical Fidelity as I know it pairs well with Vandersteen speakers.  If you can find an M6 at that price, excellent as they tend to sell used for a bit above that.  The M5 at 150w would work and I am sure that you could get to your target price either via haggling or trade in on new gear.  

Full disclosure, I am an MF dealer and am a bit biased.  That being said, a user out on stereophile has had an MF M6PRX amp paired with the Treo's and has raved about it for years.  MF and Vandersteen work very well together.
