Seems like we're looking for either 1) a really great pre, a decent mic and a decent soundcard OR 2) a really great mic, a decent pre and a decent soundcard OR 3) a really great soundcard and a decent mic and decent pre. I can't see you getting two "really great" anything for that budget. $2000 IS a lot of money, but to get a "gold channel" it's a bit short. $3k - $4k and I think you can really begin to make things happen.
Option 1:
PRE: Consider the Great River ME 1-NV or Grace 101 or an API module or an FMR RNP or.... Sebatron 2 channel (limited info out there on this one)
MIC: Studio Projects C1, Marshall V69, Shure KSM (several here), used Audio-Technica 4050 (the 4033 is too limited in its sound to be the only mic) or low end ADK mics
SOUNDCARD: Lynx Audio One,
MAudio Delta 1010,
Echo Audio Layla or possibly the Lynx Audio Two L22 (depending on which mic you buy)
CABLES:
www.markertek uses Canare cable for it's "house" brand... I"ve got some... good stuff on par with Mogami (which I also own). Full compass has mogami at reasonable prices. Good cable is not negotiable here so Mogami, Canare, Belden or similar quality are minimum. Don't pay big money for Monster... it's a rip.
Option 2:
PRE: RNP (isn't it amazing that the RNP could be your "gold pre" yet is priced to also be your "decent" pre
MIC: Soundelux U195 or Lawson L47SH ($995) or one of the high end ADK mics or ... one of the B.L.U.E. mics or a used high end mic for ~$1,000
SOUNDCARD: same choices for soundcard
CABLES: same as above
Option 3:
PRE: RNP
MIC: Studio Projects C1, Marshall V69, Shure KSM (several here), used Audio-Technica 4050 (the 4033 is too limited in its sound to be the only mic) or low end ADK mics
SOUNDCARD: Lynx Audio Two (pick your type A, B, or C)
CABLES: same
