Can't say, but no correlation... The performers are the same, but it's not like I have compared it to various other performances of the same pieces which might be almost as good, and maybe better, on CD. These test presses are the best I have heard where both the performances are great and the sonics are unparalleled. As I said, even the first edition (ed1) of the 5th, which follows the test press, did not have that magic. So where remastered CD is concerned, I strongly doubt.
This is where ability to stream helps as you can quickly check which of the various performances of the same piece you prefer
The Kogan Beethoven violin concerto ED1 also costs the same amount of money, 5k GBP plus, as the Brahms ed1. Never heard the original, but I have a testament reissue which I do not like. ?? . If the CD is like the testament, well... Then you are just buying to have the performance instead of the combo of both sonics and performance. This is where ability to stream helps as you can quickly check which of the various performances of the same piece you prefer
To summarize: should you have the CD for the performance, yes. Will it give you an effect of good stage, flow, tone etc compared to others, I doubt
