Pass Labs X-1, X-2, X-0


Has anybody auditioned the Pass Labs x series pre-amplifiers? Were there any substantial differences in sound quality? Please tell me what you think?

Hi Joe - I'm waiting for my used CJ PF-R preamp to arrive. If it's not quite what I'm looking for, I'll be searching for a deal on a used X1. My amp is a CJ Premier 11a tube amp. ...Abe
Yes the Pass X-1 is definitely better than the Aleph P, but that is not saying a whole lot. I am a Pass Aleph amplifier owner and a clear Pass bigot when it comes to the Aleph amps and I have respect for the X series amps, but, IMO, the X-1 clearly doesn't measure up to the best tube preamps. According to Pass, you have to leave it on all the time in order for it to sound its best and I've heard that while it sounds better, it never achieves that A-1 sound which can be had with some of the best tube equipment. In my audition with the Pass X-1 and the X-350, I heard an overly heavy bass and no midrange sweetness. Certain musical passages were overly bright. If you compare it to the Aleph P, yes it sounds great, because this wasn't an exceptional preamp at all. I completely agree with Jtinn and Topkat. Pass Labs has a great reputation for designing amplifiers, but that reputation does not carry over to preamplifiers.
I owned an X-1 for a year until the Krell KCT demoed a-b against the X-1 in my system. I was very surprised in the difference. The KCT was much more neutral and definatly cleaner. I sold the X-1 bought the Krell. The X-1 is still a very good piece.
