Which Amp.

I have been talking with a friend of mind trying to determine what will be my next purchase we both agree that my amp which is a Mark Levinson 23.5 should be upgraded. But with all that had been going on with Mark Levinson I’m afraid to continue that route. Also there 4x line just seems “Proceed” to me. I have been looking at Pass Lab amps of late (X350 & X600)
The question is do any of you think that Pass Lab amp would be a good match with my system, or do you have any other ideas or opinions. I would like to purchase use on Audiogon
