Peter-the ZDSE has been known for years as one of the few OTL amps that pairs exceptionally with both high and low impedance cans. Outputs at both 3 & 12 ohms.Uncle Erik has an incredible write up about why the Zana can do what it does...I'll dig it up sometime. Get on the ball man.
I guess I've never really looked into the ZD specs that closely. Just heard it once with the HD800s (300ohms) and never with low impedance cans.
I'm looking forward to that imminent pairing myself with the fully-powered GS-X MKII. I know there's historically been a difference of opinion between us as far as gear, but since we seem to share an appreciation for the HeadAmp Dynalo-based amps, I find your comment to be especially encouraging. It seems like there will finally be a combo of gear that we can agree on is good.
I agree about the ZD as well btw - a great amp for both low-impedance and high-impedance headphones. I like the fact that Craig (Eddie Current) personally uses the Audio-Technica AD2K with it (which is a quintessential low-impedance high-sensitivity headphone).
Looks like we're in Bizarro world here...we both completely agree. That said, the GS-X / TH-900 (I've got the upgrade modules in mine) is simply breath taking. You should be very happy with the pairing.
Been meaning to give the AD2K a try, but with the newer version, I've put that off a bit.
