OK, let's suppose you have been a Buddy Holly fan over many years, and your collection already includes most or all of his recorded work...
In 1979 or thereabouts, your enthusiasm may have been such that you decided to fork out quite a lot of money for MCA Coral's excellent 6 album box set "The Complete Buddy Holly", superbly documented by John Beecher and Malcolm Jones, and packaged to a very high standard.
And then let's suppose that, in recent years, you decided to transcribe your vinyl (or cassette) Buddy Holly tracks to your rapidly growing digital library, for the huge enjoyment and convenience that's in it.
And then let's suppose that, as part of the transcription process, you chose to fine tune the audio tracks using Sonar, or Pro Tools, or equivalent, adding just the right amount of compression, tweaking the EQ to suit your room and sound system, and maybe fixing some of the timing errors in the "originals" (the opening to "That Makes It Tough" would be the obvious example).
If this is the case, then my opinion is that you should save your money and disregard this over-hyped over-priced offering. It will not sound as good, in my opinion, as what you already have. There is very very little in this RollerCoaster Records issue which you do not already own (seconds rather than minutes).
The sound quality is very unpleasant to my ears, very very trebly, and the listener gets the impression that these producers had their aural faculties shot to hell many years ago, such that they can no longer pick up the higher frequencies on a good original. So why are they claiming to have achieved top quality results?? In my opinion, it's because they have fallen into the trap of believing their own bullshet. This CD sounds pretty lousy to me. Yes, I realise it's a totally subjective view. How could it be otherwise??
Why have I decided not to return this to Amazon and ask for a refund?? Because one of the accompanying booklets - the John Beecher content, anyway - is very good, and I think I'd like to hang on to it.
(The other accompanying booklet is a RollerCoaster Records catalogue, which I threw away).
