Claude’s amp upgrade recommdation

On a whim I asked Claude what it thought the weak link is in my system (see my Agon profile).  It said my Peachtree Gan1 power dac was the limiting factor.  I gave it a $4000 replacement budget and it recommended a Luxman M-700u.  Great amp, but the only one available used is here on Agon for $7700.  I reduced the budget to $3000 and Claude said a Cary CAD 120SE.  There is one on Agon for $3800 and one on USAudio for $3250.  As a second choice, Claude recommended a Rotel Michi M8 for some reason. The cheapest used one is at TMR for 9499!  As a third choice, though, was an Emotiva XPA-2.  TMR has one for $1199.

i had been thinking of maybe class D monoblocks, but Claude said they would be a poor.match with my Stirling LS3/6 speakers.  Quite a range of suggestions.  Would the Emotiva be an upgrade on my Ric Schultz modded Gan1?  Is the Cary the best choice if the Luxman is above my budget?  What do you think?  Thanks.
