Your choice is basically a catch-22. You can get the 60's (and an amp) which is often stated be not be significantly helped by helped an amp, or the 80's, that some people feel only reach their full potential with an amp, but you can't get it. I did spend time with both of them ampless and I agree the 60's sounded overall a tab better (and I think slightly more efficient - though I can't explain way) than the 80's. The 80's though are no slouch. I went 80's ampless until I got an amp and didn't feel like I was missing anything during the wait. So you may want to go this route if you want to grow. In addition if you're running them off something with a decent output (do you know of the quality of the D-EJ955?), the amp "necessity" (which itself is up for debate and may be the disagreements are because of this) starts to disappear. You can also just get the 60's with no amp and save up for a future phone/amp combo (as you've seen upgradoing is a disease here). You can go used from the for sale forum, and pick up the 80's and amp for your 60's/cmoy price. If though you pay new prices you may also want to consider the
Alessandro MS1's as a jump over either for $10 more (though free shipping) over the 80's. This may be your best bet. Sorry to make it more complicated.
And you may want to check out the
Ampless Ratings for different opinions of which sounds better ampless. There's certainly disagreement.
Hope I'm not stating the obvious, though this gets asked very often. Good luck.
