Pass Labs X-1 vs XP-20


I recently decided to explore upgrading my Pass Labs X-1.  Reno HiFi supplied the Pass Labs XP20 for consideration.

My current system is as follows:

  • Primary Source: Michell Gyro SE (upgraded powersupply HR and Orbe Clamp) SME IV and Shelter 90X (on a SolidSteel WS-5 wall shelf)
  • Pre-Amp: Pass Labs X-Ono and X-1
  • Amp: Pass Labs XA100.8
  • Speakers: Magnepan 3.7i and two (2) DWMs
  • Cabling: Audience Au24 SE
  • Power: Audience aR2-TO and dedicated 20A circuits (two pairs of each)
The XP20 is in a different league with regard to detail, transparency, soundstaging laying and especially quietness.  On first listen, it didn't seem much better.  I gave it a few hours of warming up (mind you its used unit so break-in wasn't the main concern) and listened again.  Music appears from far blacker blacks.

The remote is night and day better than the older model.  As I use many of the functions (ext amp power, display reduction, mute, etc), it is much more useful.

On the negative side, it is a bit brighter than the X-1 very occasionally sharp depending on what you feed it.  An although can reach higher dbs than the X-1, one could switch the X-1 into high gain mode.  The XP20/XA100.8/Magnepan 3.7 combination can reach loud levels but not unneighborly loud levels. I would say the X-1 gave out a bit more but at the expense of audible grain.

Minor nit-pick, the unit is a bit larger and doesn't match the X-Ono.  The X-1and X-Ono, like the XA100.5 series are a bit more industrial looking and beautiful in my eyes.  The XP20 may even be a slight bit lighter.  Also a very minor nit-pick, I actually liked the smaller black box external powersupply that could hidden away.

Before pulling the trigger and switching to the XP20, should I consider anything else.  I imagine the XP30 would be even a bit better and give a bit of the X-1 more romantic glow.  Its really a bit out of my price range right now.

Thank you for reading, and your thoughts are appreciated.

I don't know if you are looking for a different flavor than the Pass,  but Coda 07X has a very similar sound signature as the Pass.  I do know of 2 People that have chosen it over Pass products.  Coda has a returned unit listed on ebay right now for about 1/2 price... I've heard this unit a few times with Bill from Legacy.  It is certainly in the league.

I hope this helps,

I’ve owned a number of preamps over the years. Had a CJ Premier, and a total of 3 Pass preamps, among others. The XP20 is the best preamp I have ever owned and not by a small margin. Do use balanced connections with Pass gear if you can- it makes a real difference.

BTW, while the X-Ono is quite good, I would say that your XA100.8 and an XP20 cries out for an XP15
Although the XP20 is considered by many to be much better than X1, I believe the X1 to be more romantic and detailed. The XP20 goes to 60Khz and X1 goes to 100Khz!  Better for digital than phono?

I do not get a sense the XP20 is quieter. I feel your "grain" is coming from something other than the X1. I hear no grain on my X1, and it is dead quiet.

Keep the Xono. IMO it is better than the XP15.
