and that will be done shortly and published on the
www.passdiy.com site and then in AudioXpress.

What a surprise! Another Zen.

Thanks for the "Chrismas Present"

Would be looking forward to it.

Are you sure those aren't just 206E & 166E or do you mean 208Sigma or 168Sigma (or 3rd choice -- new Fostexes unfamiliar to me_)

It sez Sigma on the box, but I do find their naming convention
confusing.

(Correction - it has the "Sigma" mathematical symbol)

and the previous generation ... any look familiar?

and the 166E/206E (no S ) stamped baskets -- the others have cast baskets

Thanks for clearing that up. My confusion revolved
around the 206 and 166. Since the ones I have played
with have stamped baskets, they would not be Sigmas,
even though there is a Sigma symbol on the box.

I'm using a ZV4 with my Fe206 in back horns. Sounds fantabulous to me...but I am slowly collecting parts for a Zenlightenment, I found some really neat old stock bulbs...they look like something from a mad science horror flick. Love it. The ZL should be a better match for my suystem as I'm running a PAS2(somewhat modified) pre that has a high output impedence. I haven't really noticed any problems running the PAS with the ZV4, a little bass shy maybe.
OT... Although I am happy with the combo for now, is there anything I should do to optimize the match between the ZV4 and PAS?
