The Forte should be pretty good for 70/80 genre music, and with them and the Vincent you shouldn't be wanting for bass.
You are noticing the difference in good/bad recordings, I don't know what was going on in the 80's, forget it. Some of the 70's stuff isn't too bad.
I'm like Christian in that my bad recordings still sound better than they did on less competent systems. The EQ idea is a good one for those recordings that just drive you crazy.
I know what you mean though, after a few not so well recorded albums I'll have to play a good one to reassure my confidence in my system, LOL
The L100's might be a good move in general but they will be even more revealing than your Forte
I really appreciate you taking some time to help me through this. What I've noticed is that the simpler the music (Jack Johnson, Nora Jones, Amos Lee,) sound breathtaking, while Meatloaf Bat outa hell made me scratch my head a little. This Rose streamer may take me a while to fully enjoy, but I think it'll be a fun challenge. Thanks again.
