The 250, which employs smaller caps, is a more current design from Pass than the 350, which employs those big caps. Most other amp mfrer like Classe etc. also uses small cap in their current amp design. Smaller caps dissipate current/energy much more quicker. Sonically IMHO, it is a lot more faster and better pace and usaually more extended. That could very well be the reason that X250 outperforms the X350. Talked to Pass people a few times and have learned they didn't do anything extra to the 350.5 than they did to the 250.5. I really doubt the 350.5 would outperform 250.5. Maybe in situation that requires the extra power. But, it is interesting to see the feedbacks from other 350.5 and 250.5 owners.
New Pass Labs X.5 series versus previous X series
Pass Labs is in the process of re-dedesigning their entire X series into the new X.5 series. As of this writing X150.5, X250.5 and possibly X350.5 are already shipping. The X600.5 are expected to start shipping early in the new year. This thread is to discuss experiences with the new amps, their sound signature, perceivable improvements over the old series, and of course dissenting opinions. Everyone's perspective is welcome--X and X.5 owners, X.5 window shoppers, Dealers, and all other audiogoners with a passion for affect by the bug of audiophilia.
