Pass labs X600


Hello

I would like to know, what amp from another manufacturer is comparable to the Quality and potencial of the Pass X600 regardles of price. What amp can be consider to be as good as the X600. I'm in the market for a pair of monoblocks, but seems that I won't be able to find any X600 any time soon, so I need another options? Also what make Pass labs X600 so heavy? is it worth the weight?Any help will be apreciated before I make a decision.

Armando, Perhaps it is in fact true that things are achangin'. Even Nelson Pass may be agreeing with all concerned: Pass labs is in the process of redesigning its entire X series, to be now called the X.5. An X600.5 should arrive hopefully in the first part of next year. Do not abandon the idea of X600 yet. But you may want to wait and have a listen to the X600.5 before you make any final decisions. I know I will.
I don't think so boys. You ought to go to diyAudio.com and communicate with the one and only. The physical differences btw the X--- and X---.5: is the introduction of single ended class A bias into the circuit, fast-recovery rectifiers in the power supply, and more efficient output devices in the output stage. Also added was both single ended and balanced inputs. Pass is doing as well as ever. He just has come up with a new biasing scheme to make the X series start sound more like the XA series.
Thank you for the pointer LiGuy. I will visit Diyaudio.com as suggested. In the meantime, have you had an opportunity to compare the sound of X with X.5 series boxes yourself already?
