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.

The Pass Labs XP-20 is more than marginally better than the XP-10. At this level it's a game of inches and subtle improvements. But they all matter and up and make a "BIG Improvement". I compared the two on all aspects (XP-10 $5200) vs (XP-20 $8600) ; for the $3400 additional bucks the XP-20 is worth every penny to spend if you are serious about maximum performance from a preamp.

If I gave a score to rate both preamps for overall, the XP-10 would be a 8.5 and the XP-20 would be a 10.

But again the XP-10 is no slouch. It's just the XP-10 takes it to another level to world class performance. That is why I personally chose to buy the XP-20 so there would be no regret.
MrChips,

I have had my unit for 4 days and have played if for about 20 hours so far. The first few hours sounded nice, and it has just gotten better. It seems like most of the break in occurred during the 1st 24 hours, but I have heard some improvement since then.

Ozzy,

I actually have a Hi-Fi fuse that will fit the XP-10. I may try that later. I ended up spiking the plaform the XP-10 rests on and put a light sandbag on top of the XP-10, and the unit now has the perfect blend (in my system) of detail, crispness, bass detail and warmth. I am afraid to experiment right now becuase it sounds perfect to my ears as it is.

But, like the rest of us, I am sure the temptation of even better sound will get the best of me, and I will try the other fuse. It is an easy test. :-)

I am lucky that so far all my sources will work with the 0 Gain setting. It would have been better though if each Input could have a different Gain setting.

I also wish that we could select Balanced or Unbalanced for the Bypass. That could be a software option I'm sure.

I'm glad you found a cord and outlet that works for you. Synergy is the key, eh?
Dmccombs, My suggestion is to keep it simple and dont change too many things during the break in stage so you can tell what is happening.

Once the unit is broken in, unplugging it will cause a loss of sound quality for a short time.
At first it took hours to return but now it only takes a few minutes.

I have tried sandbags and spikes and thus far find that my X10 sounds better with just the unit sitting on a quality spiked platform (or shelve).

You are lucky with the gain settings, I have a Cary 306 SACD Pro CD Player and it has a huge difference in output compared to my other sources.

You will really love the X10, it is a pure sounding gem

Dpac,

Nothing is getting in the way of enjoying the music. I have played the heck out of this thing and am having a good time. Just because I have also tried some simple tweaks doesn't change that. I have enjoyed numerous CD and movies. It is possible to do two things at the same time.

Did you have a bad day or what? WTF?
