Romance vs. Reason
Anyway, I'm just skimming this thread and see that you're fairly enthusiastic about Stax, so I'd say just aim for the O2 right now. It's inevitable at this point. You'll get the O2 within the next year whether you like it or not It's the way things work around here.
Problem with this reasoning is that I have no amp to drive the O2s and putting out for even a used O2 and a used 007mk2 at the same time is bending the wallet a bit far. It might break. Thinking: maybe an interim combo that sounds like it would be a step up from the 34 set that is yet very affordable. Then read a lot more from the various threads. Determine the eventual replacements and then replace the amp and then the phones.
Not as romantic as taking the great leap upward, but I think that if I do, any sonic extasies will be tempered by the downward plunge into frigid fiscal eddies.
Whew! Actually sounds exhilerating!
