Well, You are like me or sound like I.
I have owned the 80's ver.1 though or well before they came out with a ver.#
I auditioned the 80's and 60's , they were sold instores, so they had the 60's beside the 80's. in the same room same amp and same music and movie scenes.
If you go Factory Outlet for the 80's then you are not spendind alot more than if you were to buy the 60's..not factory outlet. You already are prepared to spend for the 80's and yes, I think the 80's are worth the extra, nothing would annoy me more than getting the 60's and sitting there thinking I had the money and that extra bit of sound I could of had.
Go with the best sound you can get with what you are prepared to spend.
I was looking at Paradigm 60's and 100's but, the Axiom 80's are better than the Studio 60's and about Equal to the Studio 100's but the Studio 100's were not $1000 better. Then I knowing I am going 7.1 started inquiring about the price of the other spearkers Centre and rears and it shortly went out of the ball park.
I say if you are willing to spend on the 80'syou may as well go for it cause it will haunt you forever. The factory outlet M80 are $1300
