Comparisons between Pass Labs and Pass/Threshold

I can vouch for the Pass 0s. It blew away any solid state amp I compared it to. I heard friends jaws hitting the floor when my Martin Logan Quest's started playing. I would set them up by telling them it was "only" a 40 watt amp. Other amps that I also have enjoyed are a Plinius SA-100 MKIII and an ARC 100.2 both at 100 watts per channel. Since I own a pair of Coincident Partial Eclipse speakers, I can drive them with an AES DJH Superamp and have not even considered solid state. Good luck finding a match for your speakers.

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.
