Moon North Collection Versus Pass Labs X350 - Which would have that liquid sound?

With the right cables either will be very transparent/liquid sounding or either could sound like $hit. 

I’ve had the 761/791 and pass X350.8, Xp22, and also paired the x350.8 with Luxman C900u. I agree with RSF507. Too dependent on speakers and room of course. I def got the moon combo to sound awesome and same with Pass setup..but that being said the big pass will likely have a deeper image and slightly rounder more romantic presence region. It also runs wicked hot 🥵 and you need to put it in a cold basement or open airy room for least intrusive day to day living with it. 

I haven’t heard the Pass combo, but I have heard the North 761/791 vs the 861/891 at some length. The 800 series is more resolving, smoother (more liquid) and more musical though both series are very, very good and a signficant step up from Sim’s previous offerings IMO. I also agree with @audiopacer in that there are many factors influencing the result but the electronics are unlikely to be a limiting factor. 

I ended up purchasing the 761 amp for my 2nd system as it was close enough for me and would fit in my cabinet! There is a greater difference in the 891 vs the 791 preamp/DACs.

If I hadn’t already been well down another path with my better system, I would likely own the 861/891 pair. Elegant and simple with remarkable sonics.   

Best,

I'm a lttle unsure of exactly what liquid is, but having been an owner of a Pass x350 for many years... I would say look at a Pass XA amp, not the X series. 

@audiopacer Do you still have both systems? If not, which one do you currently have?
