one thing you could think of is getting some amps for your 60's to see if that will make you happy.. i have a 5 channel marantz, and it has no problem pushing the 60's that i have to any level of sound that i want them to go to... if you get the amp's which you are saying you might want to get anyhow, and try them with the 60's you have lost nothing, and you might find out that is all you needed.. on the other hand if you decide you want to still get the 80's then your already set up.. remember, for every 1 db it is 2X as loud.. i think......
