Pass Lab X1 and X250 - Which XLR?

Since owning the X2.5 and X150.5 I haven't cable swapped, I have only used Audience Au24 and have no plans to try others at this time; take that for whatever it is worth. In a past setup I compared the Acoustic Zen Silver Ref II and chose the Au24, again, take this for whatever it's worth. You may also want to consider the IC's from Pure Note.

The Pass gear is very critical of cables (like my Krell). I suggest you spend more dollars now instead of buying upgraded cables later. My suggestion is the Pure Note Cerulean. These are phenomenal cables for the money and you won't have to upgrade. Do a search and you will find many positive posts on these.

Acoustic Zen Matrix II between X250 & X preamp & AZ Silver Ref II from CDP to preamp, all XLR, was the best combo I found with my rig, tried others that were more $$$$.

I've tried many IC's with my Pass X-250 to Sim P-5 connection. I ended up sticking with Audience AU-24 XLR's. Great synergy with the X-250. They're the best I've used (including Cardas Golden Reference, Neutral Reference, Acoustic Zen Matrix and Silver Reference, Ridge Street POIEMA (a close runner up) and the Pure Note Epsilon Reference V4 (another Excellent contender).

Enjoy!

Virtual Dynamics is a great match to the Pass gear, especially between the X1 and X250.
