"(2) As for the SACD player, there are so few discs out there these days and the difference between regular CDs and SACDs will be so slight as to go unnoticed in a system like yours. Save your money and use it for #3 below."
I agreee 100%, I feel that the limited amount of available music, mostly classical, makes this format unpractical.
I also agree about the cable/wire issue, this should be the icing on the cake, not the cake. Once happy with components and speakers, then do wires, for the money Kimber, Audioquest and Tara make some nice stuff. Don't go crazy here and don't buy into the hype, $2000/pair speaker cables, $1500 interconnects at least to me are overkill, save your $$$$$ for better speakers as this is where huge leaps can and will come from.
