Gryphon amp, preamp and DAC! 

Please explain your goals and what you're willing to do to get them.  You say you're not an audiophile, but the Wilson is a very large and heavy loudspeaker that requires certain type of amplification and room placement.  So are you planning on optimizing the Wilson's performance, which requires you to get kinda' audiophilistic (acoustic room devices, esoteric cables, vibration isolation equipment stands, etc.), or are you just going to put them where they look best and they don't interfere with the room decor?  If it's the latter, then any of the more powerful McIntosh integrated amps will work very well.  A Wilson dealer can give you viable option if you want to optimize performance.  Basically, you could spend another $5k or $50k depending upon your goals.

The Gryphon Diablo 300 is also a great choice and being integrated makes things "less complicated" because you would have fewer cables, which you should also budget for - look at Hijiri cables

Then there are options from Simaudio MOON, or Bryston, both made in Canada

Perahps Ayre or Pass Labs would also be a good choice?

There are lots to choose from

I have repeatedly heard great sounds with Roland equipment from Wilson speakers.

Given your question, I highly recommend buying all the same brand. I have been slowly upgrading my system for fifty years as fast as I was able to afford it. But my system snapped into perfection for my ear when I put in the final piece of Audio Research. The most natural, musical, yet detailed system I have ever heard. You can get all ARC Reference components for around $100K.

I recommend listening to complete line ups of Roland, ARC, and maybe Pass. Given your budget… fly to a city with all available. Make appointments with dealers for them to set up what you want. Spend several hours with each. Don’t be analytical… listen to music and see which brand grabs your heart. If one brings tears to your eyes… buy it.
