SZ2 are current production. Also amps... I think I posted someone's FR graph here a year or so ago recording no difference from 252 on up to 717 at very high amplitudes with an 007a. This suggests to me that Stax amplifier differences lie in the ultrasonic region. On the other hand I haven't heard any amp other than 323S, and this puts me in contrast a little bit with others here.
Thanks spritzer and justin. That's good to know.
I've also got flecks of debris between the hard case and the sealed plastic packaging. What I'm trying to do is figure out whether it's actually new or I'm getting someone's monkey model.
Edit: yeah, It's an ebay purchase. I'm not in the states.
007 bought. The L300 would have been a more sensible choice, but prudent purchasing can sometimes feel stifling. Make sure you've all got earpad spares.
Go over them again for me please.
I know they've reworked the cable relief and have had channel balance problems to an unknown extent. I'm going to be buying one so long as it doesn't get overpriced like the new 700 amplifiers.
