Bach Unaccompanied Violin Sonatas-Johanna Martzy

Both TAS and Stereophile have published articles about the vinyl reissue of these recordings by The Electric Recording Company at the staggering price of $470 per disc (yes, you read that correctly). Is anyone aware of CD reissues of these recordings in high quality sound? If so, could you please reply with the details (label, album number)? Also, a comparison of the original vinyl to CD reissues (if such reissues do in fact exist in good sound) would be most helpful. Thanks.
