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

I had pass  int-60 and int-250 in my system with Sonus Faber Serafino and Amari tradition speakers. I kind of agree with Eric. To me pass sounded a little mechanical and I could not get rid of this feeling, until I changed pass to luxman. First it was luxman 590axii that to my ears was more organic than pass. I changed it later to luxman 507z and sound became liquid with better bass and blacker background.
now ordered luxman 509z. Should get it soon. The luxman gear requires at least 400 hours of burning before you can make comparisons. Otherwise to me luxman all the way.

Please keep in mind that in my prev post I reference only integrated. I don’t have any hands on with pass or luxman separates. 

I will have to burn 509z for many hours. The mistake of some owners (I was there too many times) to make conclusions before sufficient burn. It costed me a lot of money to ignore burn in significance, system synergy, isolation and room acoustics.

Ryder,  yes 590axii is terrific integrated - if your speakers are not demanding a lot of power. In some cases I felt that bass is a little shy and missing some articulation. When 507z came out, my dealer sent me well burned unit. Again the key to luxman integrates - especially latest z series is sufficient burn (at lest 300-400 hours). The 507z had deeper, more resolving bass in compare to 590. This I expected, but what surprised me is how 507z presents overall sound - more liquidity, blacker backgrounds. It’s also more resolving. I guess new technology contributes to all that. This Thursday 509z should be delivered. I did not hear it before pushing the bottom, but regardless - it should be a keeper for a long time. Even with 507z I feel like I can leave with it and just enjoy the music. Of cause all is ear and system depended. 

If anybody interested, I got luxman 509z last week.  I traded 507z towards it. The 507z is already build like a tank, but to me the 509z build is another level up. The speaker terminals, top cover , side panels - better quality. But what surprised me the volume knob and input selector knobs are also on a different level- smother and more precise. 
i got mine brand new and now it has about 30 hours on it, I already  can say that it’s even more naturally sounding with even blacker backgrounds than 507z. My personal opinion - when burned for 300-400 it will exceed 507z on all levels. 
With every solid state integrated I personally owned (pass int-250, gryphon 300, plinius hiato, accuphase E-800, gamut 150, luxman 509x, luxman 590axii, mark levinson 580.5) i always herd some hardness at the beginning. With 509z - not a case. This 509z is  a real gem. Granted I learned a lot for the last few years about system synergy, cables, isolation - so it’s all contributing to the sound.
I am just a customer and not affiliated with luxman in anyway.
