Which Pre-Amp Pass Labs or Audio Research

I`m now using The Pass X350 Power Amp and a Audio Research upgraded LS22 preamp. I`ve also used the Ref5 both preamps sound great the Ref5 was just adorable much better control etc. Im wondering would the Pass Xp20 or Xp30 be a better way to go. I`v heard the AR preamps are much better than the Pass Labs Preamps.

I have owned the Pass XP-20 as well ARC Anniversary Ref 40. Very, very different sounding and you'll hear that difference immediately. It's hard to say which you would prefer as you don't say why you are dissatisfied with your current sound and what type of music you listen to primarily. Help us out please.

I posted a response in my system description but here are some further thoughts. I don't think tube usage would be an issue with the Ref5 unless you leave the preamp on all the time. My Ref40 warms up in an hour and doesn't sound much better after that. The signal tubes will easily last 5000 hours and are not that expensive.

If set on Pass, read the description of the Xp-20 v. Xp-30 here at dagogo:

The XP-30 would be my choice if you wanted to go with the Pass preamp.

As another less expensive option, I don't know whether you have tried different tubes in the LS22?

I also found this article of interest. I have tried these specific types of mods in other equipment with terrific sonic results but few people have the skill or want to damage the resale value of their stuff:

Good luck!
