Comparisons between Pass Labs and Pass/Threshold

Can anyone offer listening comparisons between any of the new Pass Lab amplifiers and the older Pass-designed Threshold equipment? I presently own both the Pass/Threshold S300 and the S550e, the former purchased new and the latter purchased used/mint. Those are the two older Pass amps I know best. Do they have close counterparts in Pass Labs amps? Is it worth trading up? Those are the kinds of questions I am most interested in. Thanks much.

All of this makes me think I should find a way to hear the Pass Os. Thanks much.

The Pass Aleph series amplifiers sound quite different from the current X series. I have owned both and can recommend both, though my preference is for the new stuff.

In the Aleph series, the 0s are from the original 3-gain stage design, whereas the Alephs 3, 4, 5 and I believe the 2 are from the later 2-gain stage design.

Has anyone else listened to the PL X series? I can't recall reading any Audiogon comments.
