What if Neil have made all these testimonials to make the artists be aware and send him the master-tapes for new remasters?
HDTracks are selling what they get from the music companies and that is not always the best. Sometimes things have been up-sampled and have a lot of dynamic compression. The music companies often do not have the actual master-tapes, they usually have some digital remaster saved or a tape copy. The master-tapes is in most cases in the belongings of the artist at their home or something. Neil knows this and if he want better sound-quality than what the music companies have he has to get it from the master-tapes!
Listen to Dave Grohl at 5:53: "We'll send you the tapes!"
With the master-tapes Neil will be able to make fantastic sounding new digital remasters at the highest possible resolution without dynamic compression! I wish this is true, I wish the ponomusic-store will be something special!
