Should I Sell My ARC REF 6 and Get A Pass Labs XP-32


So here's the question.  I love my ARC REF 6.  It's a great piece of equipment.  But  lately, I have been thinking that maybe I should switch from tubes to a Pass Labs XP-32, as I don't want to worry about replacing tubes in the future (like 5-10 years from now -- I know that there is plenty of stock now and I have a spare set anyway) as I approach retirement age.  Of course, other than buying a Pass Labs XP-32 and putting it into my system to see how it sounds, I am at the mercy of professional reviewers. The rest of my system: I have a Pass Labs 250.8 (so I think that there would be great synergy with the XP-32), MSB Discrete DAC with Premier Power Base and Wilson Sabrina X speakers, and a full loom of Shunyata cables.  Will the XP-32 be an improvement over the REF 6 for my system?  Should I sell the REF 6 and get an XP-32?

I had the ARC Ref 6 in my systems for almost a month, courtesy of my buddy who let me audition it on its own and against my XP22. The amps are X260.8 mono blocks.

The Ref 6 is an amazing preamp. It throws a big, holographic soundstage with images that are slightly larger than life (this is both a Pro and a Con). Great combo with Pass amps. Natural sound, really nice.
With the XP22 in place of Ref 6, I get a more realistic presentation with soundstage nearly as big as Ref 6 but with images that are more lifelike. Better bass speed and definition (Ref 6 is a bit sloppy and wooly in the bass). Mids are, believe or not, slightly clearer with the XP22 and the highs are a bit sweeter/more extended. Volume control on XP22 with the X260.8 is more granular than on the higher gain Ref 6. With ARC you get bigger jumps in volume with each click. The XP22 has blacker, quieter background than the Ref 6.
I spent a good amount of time evaluating the Ref and comparing it to my XP22 to reveal these differences. Both preamps are excellent. In the end, I thought I would miss the Ref 6 but I really don’t.

To conclude, if I was to make the move up the preamp ladder, the XP32 would be at the top of my list.

@audphile1, thank you so much.  That is exactly the type of input I am looking for.  I understand that the XP-32 is also quite a step up from the XP22 as well.  It sounds like the differences were rather subtle, since you say that you spent a good amount of time comparing them in order to discern the differences.  I am wondering if even jumping to the XP32 will be more than a subtle change.  I originally was using my MSB DAC as a volume control.  The ARC LS28SE was lent to me by a dealer and I thought that there was very little if any discernible difference between it and the MSB.  Then I tried a VAC Renaissance Mk V, and slightly better than the ARC but again, not worth it.  Then I tried the ARC REF 6 and it was a definite improvement over the LS28SE and the VAC.  Sounds like I really need to just bite the bullet, put it in my system and sell the one I like less.  What are you using for speakers?

I tried this about a year or so ago. I traded my REF5SE in on an Ayre KX5-Twenty as I wanted to get away from the tube heat. Within 120 days I sold the Ayre and now have a LS28SE and am much happier. I never have heard any PASS gear except at Rocky Mtn Audio Fest so not a fair assessment. Although I may consider PASS should I look at new Amps. I guess my point is make sure you’re gonna be happy before you jump.
