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

Take a look at Sugden,Masterclass series. I have been completely satisfied with their amps. My main system has had the SPA-4 power amp and LA-4 pre amp. I sold the power amp, and bought a pair of Sugden MPA-4 mono blocks. I am not ever giving them up. I also have a second system in the basement, with a Sugden IA-4 integrated amp.  We all have a preference, and I have never been one for clubs or group thinking when it comes to making purchases. 

As usual, opinions are like buttholes. I may as well share mine. I owned and sold several pass labs amps of recent design. Why? I did not like the sound, period. This includes both class A, AB, monoblocks, and stereo .8s.  For lack of a better description of what I didn't like about them I felt they were lacking in detail and seemed a little fatiguing at times. I finally brought in a new Luxman 509Z. It is the best amp I ever owned. Sounds amazing to my ears. 

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. 

Hegel and save a bundle. :)
