Please Recommend Audiophile Solo Piano Recordings

ZUIO, are you looking for CD, LP, or hi-rez/SACD?

Nightfall, on the Naim label, while not quite solo, has one of the best piano sounds I've heard captured in a recording.  Very real.  You get Charley Hayden thrown in on upright bass for free. The music is a bit too much "new-age noodling" for my taste, but the piano sound is superb.  Available on vinyl, cd or download.  

One good option is to find labels where the house sound is of high quality (or at least one you like) -- that way you have lots of choices

Two that come to mind that I like are

1) Steinway, for example Bach on a Steinway
2) Hyperion, for example Angela Hewitt

Or for a more audiophile minimalist option Ito Ema Goldberg Variations on M*A recordings

Thank you all so far. Btw my preferred format is digital download.

One of the all time best in the jazz category, and any jazz fan knows it, is Herbie Hancock Piano. Prepare to be blown away. sbank above suggested Brad Mehldau which is another excellent recommendation in the jazz category.
