Pass labs X600

Thanks Guidocorona, I will too.

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?

Guidocorona, please let me know what did you find out?

Armandido, the X350.5 is now already shipping. the Pass engineering team is now concentrating on X600.5. I have spoken to Pass Labs in the last 10 days. The X600.5 should start making music by mid December. It is likely that the new monoblocks will be shown at the Vegas show in January.
By the way, if you want to know more about the new series, I have started a thread to discuss differences between X series and X.5 series.
