best preamps

@jhamond987 

When you said unlimited budget, how far do you want to go? Are you looking to get just the linestage preamp or the entire setup and system? What are your current setup and system? Did you already have a setup or trying to start from scratch? 
Without knowing the rest of your gears, If you already have a setup, it's hard to make recommendations. 

I love my McIntosh C2200! Used under $3500. 

Unlimited budget means a call to CAT, MBL, or dartZeel... they can hit $100k if you want to burn some cash

Unlimited budget could mean a call to Naim Statement gears, Boulder, Tidal, MBL, Soulution, CH Precision, Burmester, D’Agostino Momentum series, etc. They can hit close close to a million dollars for the shoe setup and system.

Refurb Audible Illusions L3A linestage or Modulus (w/ phono stage). Tubes.
