I have bought quite a few of these Avid collections and found all of them to be excellent value. The sound quality of all the CD's I have heard are very good. I really cannot understand John Gregory's comments about sound being "terrible, almost unlistenable" as I doubt whether most people will find these anything but enjoyable. I admit that I do not have the old Vinyl copy to compare with but I do have a very good and very revealing Hi-Fi system yet find no fault in these CD collections.
All the CD collections I have tried from Avid represent exceptional value, this one included. They are not just enjoyeble for those of us who enjoy Jazz of the 1950's but at £3.99 well worth sampling by those who are not familiar with the likes of Dave Bruback, Stan Getz, Barney Kessel, Lionel Hampton and so many more superb musicians. Don't let a negative comments from a purist put you off. Obviously they were recorded onto tape over 50 years ago and lack the fancy digital dynamic-range enhancements. They are simply great sounding disks and a very enjoyable listen, whether you use a high quality Hi-Fi or iPod.
