Looking to downsize and for suggestions for amp(s)

You didn't state your budget, however you could consider some stereo amps such as the Coda S5.5, the SPL Performer S-1200 or S-900 amps. You will likely need to get new speaker cables though if you want to put the amp in your rack.

Being being part of a large multi state audio club 

AGD audio, small but  packed  with the best in gan Fet technologies 

the $11500 monoblocks imo beat any amplifiers under $20k

see the reviews then get a demo ,Highly Recommended.

The AGD are a pretty easy recommendation but,

for what it is costing them in parts are at least 20%  the best is R&D markup 

imo  and I have heard 2 models both are good  the model that looks like a tube is very clear but a bit light in the bass .you have to go to the $11500 monos to get the whole package , the Atma sphere is probably a better bargain .

everything improves with technologies ,I am still waiting onRalph to come out 

with a upgraded model ,it’s several years old . Even AGD has had several evolutions and is module , these are all question  that can be perplexing.

I want to thank everyone for their suggestions.

As I am hoping to put some coin back in my pockets for perhaps another upgrade down the road, I think I will look at something in the used market first. I had been a little suspecious of the ARC ss, but since I have never heard one, I think this should be my starting point.

Taking a fast look at what is currently around something like this can be picked up so I can spend some time with it to make a determination on further direction (if any).

Will let you know...

Thanx again

You had a lot of good suggestions, especially the AGD and SPL. 

Similar price to your Pass you could get Aavik P-280 which is a great performer.
