Thanks for the reply to my request but I think my intent was not well explained. I'm not interested in versions of R's concertos as I have some idea of what is out there. I like Ask/Previn having heard it on the radio+library CD. So I wish to purchase this performance and have the options of 2 different CD of the same work but that there may be one CD that is superior in sound due to the better remastering effort or whatever. I recall reading a different classical list on this very subject on these 2 sets of discs about 2 years ago, and I think the 4 concertos are the "better " sound thus No. 2 concerto would be more pleasing to me than No. 2 of the exact same work on another disc remastered differently. I have a hearing loss....and I try to buy the best deals I can. Sorry for the confusion. I think I will go ahead and buy the 2 concertos as Byron Hitchcock recommended. Glenn
