Thanks for the feedback, skullguise. I found an EC/SS on Audiogon for a decent price, so I decided to get it. If I could have found 20+ negative impressions, I would have determined that the EC/SS is not a good match. As it is, I only found a handful of impressions, some good, some bad, so I cannot make any conclusions from this (though it is tempting).
I definitely don't consider this my be-all, end-all by any means, but I am beginning to realize that with so many choices out there, I will have to do a fair amount of trading to get a system I like (did you see my thread "If I didn't like the Woo"?). It also wouldn't hurt to get to know different cans (like the Grados).
I will probably just pick things up used as they come along, try them and sell whatever sounded worse. What I don't want to do is take a risk on something that is relatively unknown (like the Elekit, which looked interesting) or too expensive as these would be harder to sell off. Maybe I end up with a Zana Deux (one of my faves) at the end of it all anyway, but at least I'll know at that point that nothing at a lower price point is comparable!
