If the difference in money is not a problem, buy the 80's now. Your upgradeitis won't be as bad.

I started with 60's and moved up to 80's because I could, not because I had too! The 60's are great speakers. The 80's play louder and IMHO a little better at low volume as well.

The EP500 is totally awesome! Your whole house will be rumbling and anything loose will rattle. I love mine but I do have upgradeitis for an EP600.
