Haven't read it yet, but been looking forward to it for months now ...
So hard to find info and reviews on Pass Labs gear these days ...

Nice pictures of the new UGS modules ... hehe

Great circuit porn...

How hard are those output devices biased? ~5W per device?

And how does this sound different to fewer devices biased harder?

I'm a bit puzzled... the mantra in this forum seems to be higher current equals lower distortion, but does this still apply when the current is shared between many devices... ?

Depends on the language the review should be in. Image Hifi (1/2008) in Germany has a nice review of the XA30.5 that also includes an "informal" review of the firstwatt F3. And the excellent LP Magazin (2/2008) - also in Germany - has a nice review of the new Pass Int 150. And as a bonus it has a picture of the latest (?) UGS modules that reveals the new cascoding devices

What are the plastic tabbed TO-220-ish devices edge-on to the camera?

Ok price

Hi Grey,

have a look in my schematic (AX-PP-SE (v2)) in the Aleph-X builder's thread!

:-)

Sorry, meant the specific devices. One of the pictures appears to show a C, which leads me to think they're bipolars. I'm always open to suggestions for different critters to play with.
