To paraphrase a line from the film,"The Graduate", I have one word for you: Analog.
Your whole system is perfectly assembled for it. Just plug in an analog front end.
I had a Sony 9000ES CD/SACD, and it was good, but not in the same galaxy with analog. I'm sure that the mods on the 777 will make it very good, but the difference will not be overcome.
I am firmly convinced, by my own experiences, that analog will give the best source that is currently possible, and thus give the best sound from your system.
Try a good quality TT on your system, even if you just borrow one from a friend for auditioning purposes. You will see(hear).
