New York Times article on Beatles and bootlegs

I read about "Purple Chick" (apparently just a group of obsessed fans) in Rolling Stone here Apparently, their digital remasters of the classic Beatles albums are sonically superior to the studio releases.

A related question; is there any talk of re-mastered reissues in the future or is this not a priority? Couldn't agree more that they could sound better, a lot better. It's a shame that some of these masterpieces are only available in mediocre sound!

Have not heard of these guys? Does anyone know how long this company has been in business? Are they Beatles only specialists?
