Best for under $5,000.00

If you were going to buy an amp, preamp and hook them to B&W 805(non-diamond) speakers what would you buy new? I am intrigued by the new low cost tube amp stuff(I think made by Cary)that is being promoted in the Audiogon adds and wonder if I would achieve "audiophile" level using some well choosen lower cost stuff. I play CDs and ITune sources. I know the sound is no better than the source but just currous what you all would buy new (I looked at all the used stuff) if you were buying. Thanks.
