Looking to downsize and for suggestions for amp(s)

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. 

Based on my recent experience with AGD Audion Mk3 monos I recommend replacing the stock fuses with AudioMagic Masterpiece M2 fuses especially if you are running horn speakers. Everything in the music gets very right very quickly.

Not for everyone, but Benchmark ABH2 are certainly small and light for class AB amps.
