New Pass Labs X.5 series versus previous X series

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.

Longho68, the X600.5 will not be available until the first part of the new year. You won't be able to audition them until then. I do not know the efficiency of your Sony speakers, you I can't really comment on what kind of amp you may need.

My situation: Bought a X-250 demo 3 months ago for $4200 and had a PS Audio power cable thrown in on the deal. Now, for $1500 and the X-250 I can have the new X-250.5...Thoughts? Is the list price of $6500 a firm price for the X-250.5?

thanks Guidorona, I think I'm going with the x600 since I like the look of it better..and save the extra 2k in other upgrades.....The new retail for the x600.5 is 18k vs 16k for the x600.......However, the new x600.5 will have RCA inputs as well....

Speaking of having RCA input for the x600.5?..could that mean more circuitry to deal with RCA input makes the x600.5 not as good as the x600?...

Sigmund: I own Avalon Eclipses, which also throw great backstage and imaging scenario. The sound of the combo is terrific for my tastes, but.. I recall a little more depth from the Gryphon amps.. anyway.

I am buying more CDs and less gear since the Pass is in the system...
