All these percentages boggle my mind. There are far too many variables.
I'm a speakers first guy. Find some speakers that fit your room and sound good. Then get amplification that has the right synergy with the speakers (this forum is a great place to get information on that, and a good dealer is priceless). Then buy as good a front end as you can afford with the money left over. Tweak and upgrade as you go, and have fun!
PS: Start with the room first if you can afford it.
PPS: It's no surprise the OP noticed a significant difference with a CD player that cost 7x the original. I would venture to guess, however, that the OP would have noticed an even more significant difference if he would have kept the Oppo and bought some $14,000 speakers!
