What preamp should i buy

I have had my heart set on the Sunfire tube control preamp for a long time now,But it seems impossible to find and consumers have driven the price up to the point that it is beyond what it cost new over twenty years ago. The stories of the warmth and sound stage really impress me. Now i am considering the McIntosh tube preamp C2300 which is about $5000.I do not want to spend that kind of money and be stuck with a preamp that does not sound as good as the Sunfire. Help!!!!
I have not read many articles that compare the sound of the Sunfire tube control preamp that says there is a tube preamp in that price range that sounds just as nice. When i do the independent research on a preamp that is supposed to be just as good there are always a ton of negatives....Please help, i have presently saved up $4000 dollars and want to get something with a warm sound and big sound stage. I currently have a refurbished Sunfire 300x2, benchmark usb1, Klipsh Cornwall 3's. Using a $500 dollar Chinese tube preamp which sounds nice but i would like to upgrade.
