I tried to find a meantone tempered version of K448 but was unable to.

For those unaware, our contemporary tuning system for the piano, Equal Temperament, is a somewhat recent invention. It came after Mozart. There are dramatic differences if Mozart is played on the historically accurate Meantone tuning. For a sample see [0], although note that the cheerful final passage is believed to have been composed post mortem by someone else.

This is also great, but I personally like more subtle and emotional rendition of Alicia de Larrocha / André Previn. In classical music performances the ultimate mastery is in the subtle differences, but as rule of thumb more emotional and human performances combined with clarity and precision are always better.
