Interesting that I can't find any complete tech data about them on the web.

Nor have I over the years. I recall references in German a few years
back, so perhaps they're a discontinued European release. The Russian
link shows the mod # but the headphone itself is different.

That's a loaded question. I say, buy the good phones and try them out. If
your problem is that the headphones don't get loud enough, then an
inexpensive but high-quality amp like the "Boostaroo" can help. If you need
the features that the Headwize amps provide - go for it!

Okay. I understand the potential for debate here;-). I wasn't sure
what to look for in a headphone amplifier. Volume is not an issue. I
have plenty of volume from both my Rio Nitrus and the Onkyo. I was
interested in whether a Sennheiser (or the old Sonys) + a good
headphone amp could provide reference-quality sound, partly for
appreciation now, but also party to train my ears. Like many people,
I'm sure, I think the best sounding stereo is the one that's turned
on. I want this to help me develop an appreciation for good hi fi in
order to prevent severe money wastage down the road;-)

Incidentally, while everything I've read about the 580 suggests it's
solid, I hear the 595 has a brighter, front row quality. That's
something I think I would appreciate. Can you comment?

TIA
