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

@erik_squires … “I find Pass lean, and scratchy. I don’t like listening to it for long.”

While I agree different people have different tastes. This is not at all the Pass sound. I am familiar with the overall spectrum of component sound. I would put Pass more or less in the middle, with contemporary models having much better rhythm and pace and overall well balanced tone and undistorted treble. 

I am familiar with the Luxman and Pass integrated. I would consider the Pass a big upgrade over the Luxman. It has much better rhythm and pace… sounding much more musically involving and much better midrange, both in quantity (being well balanced with treble and bass) quality.

+1 I used to have Pass and moved to Audio Research… doing exactly what you did. Yep, don’t cheap out on power cords and isolation steps can provide further improvements. I’m using springs now… I’ll probably spring for Townsend or Silent Running Audio platforms at some point.
