Many of the cds I listen to are remakes of old mono recordings, often 78s. Most are classical and opera, and old-time country and blues, with some jazz. To the extent vinyl reissues of the same recordings exist, I don't have them and thus can't compare. But I will say that many are very well produced. Assuming care was taken in the production of the cd, I don't have a problem listening through the recordings and don't get tired of them. I don't know the series you're referring to, but my suggestion would be to get one and see how it strikes you.
