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!

The OP has a budget of $1500. Why the recommendations on the Belles that is $800.00 over his budget? Read!
You should be able to get a used Parasound Integrated.  160wpc @8ohms, 240wpc @4ohms.  Seeing as they now have a newer model out, you should be able to pick up a good one for $1500.00 or so.  It also has a crossover built in, in case you want to get subs at some point.  Built in  DAC is the ESS 9018.    Probably the best sound and features for the money.
Used Rogue Pharaoh, 185 WPC. See them go at a price range from$1600 to $1900. Good match with Vandy's.
