I have been buying, listening to and collecting music since the 1950's. I have thousands of LP's, hundreds of RtoR tapes and a few CD's. When the CD first came out, I bought a player and was instantly dissapointed. I discovered that the all digital recordings (DDD) were the best, but were no competition to the what I already had. A few years ago, I purchased some video buy-out music for use on a video project. I was amazed, it sounded great on my old CDP 101 but sounded terrible on a newer player. I began to re-think the whole issue. I lucked into a Lynn CD player for almost no money and was again amazed how good some of my CD's sounded.
I think there are two issues here. First, the player, either CD or TT. No matter what recording you are playing, you need a good player. I seriously doubt that any CD player priced under $2,000. is any good. The same goes for a TT. I like my Thorens and my Grado cart. The second and possibly the most important, the recording itself. A good recording is just that, a good recording and a bad recording will sound bad even if it's played and very expensive gear.
To my ear, recordings made with tubes, or all digital recordings are the best. I also prefer recordings that use hall acoustics rather than lots of chanels which are mixed later. Modern recording tends to mic too close to the instrament and mechanical sounds get mixed in with the music. I want to hear the musical note, not the fingering sounds.
I think I should also tell you what I am using for a system, because that can also have a lot to do with how a particular recording sounds. I have a Mcintosh C24 preamp, into a Mcintosh MQ 102, into a Dynaco ST-70 driving AR 3a speakers. To my ear, old as it is, I demand accurate reproduction and think I get it. If a recording is accurate and so is the system, any format will sound good.
