Pass Labs XP-10 & XP20 Users

I recently got a XP-10 preamp. It provides tremendous clarity, a deep and wide soundstage, nice seperation of instruments, lower bass, better defined bass, and a touch of warmth (which is a plus in my system).

It has been in the system for a couple days now, and I am thrilled with the results. This thing is so resolving (without being harsh), that my friends and I could hear differences in the sound depending on how we spiked and isolated the XP-10. A sand bag on top also changed the sound. I will pick a final setup once it finishes breaking in this weekend.

I am using this in a 5.1/2.0 system. The Bypass function is setup on input 5 which is an unbalanced input. My Prepro has both Balanced and Unbalanced outputs. In theory the balanced outputs coming out of the prepro should sound better, so I have it routed through Input 1 and manually set the volume to max and Gain to 0.

Does anyone have any tips or tricks about these preamps? They seem pretty straight forward. It seems the only setup/optimization may be related to spikes, isolation, and weight placed on top of the unit.

Thanks for all the feedback and responses. They are appreciated.

At this point, I have put numerous hours on the XP-10 and it is broken in and sounding great.

I have a Hi-Fi fuse that I may try at one point, if/when I do, I will report back on that.

I guess that how one spikes/isolates the XP-10 (or any piece of gear) depends on the rack you have it on. In my setup, I found that putting the XP-10 sounded best (to my ears), by placing it on 4 spikes.

Irregardless of weather I put my unit directly on the rack or on spikes, I find placing a light weight on top of the unit does change the sound a bit. Maybe the top is susceptible to vibration?

I suggest folks with the XP-10 take a few minutes and try placing a couple of different light weight items on the XP-10 to see if it helps/hurts the sound. It is free and only takes a few minutes to try.

I heard that the newest XP-10 ( most current production ) sounds better than that of the original XP-10. Have anyone been able to confirm this?

Zenieth, Just talked to Kent at Pass Labs. His repley was, "Todays XP-10's are the same as the first run XP-10's. No difference".

Ozzy, Thanks for checking into this. I'm curious now as to why a reputable dealer would make that comment? Never the less, the XP-10 is the direction that I'm going.

Does anyone have an opinion on the XP-10 vs. the preamp section of the INT-150? The integrated has preamp out capabilities and seems to offer the same functionality as the XP-10, though I believe it does not have any gain. Of course, the two share a chassis and all of those integrated vs. separates arguments. Still, I'm wondering if, for not a lot more money, you can basically get an XP-10 plus an X-150.5 and still have the ability to try other power amps if you want.
