Have Luxman 509x. Considering Pass Labs INT-250 or Dan D’Agostino Progression Integrated

To add a little, in the 1980's, 1990s there was a big trend of pairing B&W with Audio Research.  The Pass gear strikes me as sounding similar in tonal balance, one I never really could hear as neutral or engaging.

Clearly, CLEARLY, many audiophiles would have disagreed with my tastes then, as they do with my tastes with Pass today.  That's fine, cause you should spend money to please yourself not the crowd.

OP:  As an owner of a Luxman 507ux, and an admirer of D'Agostino I've been thinking about your dilemma. 

Honestly I find the Luxman and D'Agostino to be VERY similar.  So much so that it seems a shame to make that move, in either direction. 

I think if you really want "more and better" sounding you should instead consider going to the Luxman separates OR perhaps an Ayre.  I recommend the Ayre not becuase I actually think it's better but because it's significantly different sounding.  I recommend the separates because the additional current in the top end amps can really make a difference.

@erik_squires I get you don’t like Pass. You’ve just upgraded to a new level though by calling it “scratchy” sounding. Even lean it isn’t. That’s pretty funny.

Lean and scratchy?  Pass?  Not in my experience.  I have 60.8's driving Magico A5's; musical and slightly warm is the result.

The XA25 is a more neutral sound tonally, but very pure and certainly not "scratchy" driving Joseph Audio's.

Have been told D'Agostino's have had some reliability issues - no personal experience.

Advise listening in your home, with your speakers before changing the Luxman, if possible.

Thanks all. I’m not quite at the separates part of my Hifi journey yet. The rack, the additional cabling, etc that add to the cost are a hindrance. 
now, just realizing that the Pass is not fully integrated, I do need a separate phono stage…

constantly learning.
