Thanks all, theres a lot of good advice here. I think i need to clarify that i'm not using a sub for 2channel right now, i've got my onkyo avr set to pure direct so no LFE channel there. But where it is noticable is w/ SACD, DVD-A, and Blu-Ray over HDMI which is of course carrying my movie signals thus the LFE channel. I can live w/o a sub in my stereo setup for now but i can only imagine the extra sound i get, the quality is already there, but i just know there is that little extra something special that tight, deep, rythmic bass can deliver... that full range experience.
As for the vinyl, i like the suggestions of starting at the entry level. A friend of mine and fellow Salk owner is a big vinyl guy and has rebuilt a Technics table which he is willing to loan me until i can afford to sink in the money required for my own rig... as was said, phonostage, cartridge, table, stand, etc are not cheap.
I think i've come to realize that i really want a linestage asap, i was very very happy w/ the improved dynamics and clarity that i noticed w/ the van alstine power amp (obviously my onkyo's power stage was nowhere near the quality). Having experienced that improvement i know what a good quality preamp could possibly due to improve the sound, or maybe just "get out of the way" more than the onkyo.
so i guess i just need to figure out which way to go w/ the preamp, i think i know which way i'm leaning but would still welcome any suggestions. Then i'll work on the sub/s. and i'll use the technics until i have the money for a nice LP setup.
