There are very High Quality CD's as there is High Quality Vinyl Pressings
Each are produced with the end Sound Quality being Optimised, as a result of the recording > embedding and production process put in place.
When a CD Source is owned, especially of the Calibre owned by the OP, I strongly advise anybody with a Source purchased, that is of the qualities of the OP's Type, to experience these select Source Recordings on their own system.
I listen to both Vinyl and CD pressing from producers that specialise in the production of the better than the usual recordings.
I have also been able to hear these select recordings on some occasions as Same Album Samples on either of the mediums.
I have also been able to hear certain Albums that are select recordings compared to mainstream releases.
I will 'state categorically' that these pressing do make a difference, there is a price difference, and it is this that is seen to be a sticking point for some. There is even prejudices seen occasionally toward select recordings, as a result of the retail price.
I reiterate my advisory to the OP, before throwing monies at a rearranging the Vinyl Set Up, have a spend on purchasing a few select recordings to be used with your CD. Hopefully a favoured selection of Albums can be discovered from the producers.
I don't see there will be a need to pursue Vinyl with a intention after this experience, as the monies needed will most likely Triple to some of the previous outlays already hinted at.
The Cary, might just become the device that is under the spot light to see whare an alternative can surpass it, especially when replaying those select recordings.
Do Remember, I am a Vinyl through and through enthusiast, who has become aware of how good CD replays are able to be over the past not too many years.
If you want to experience some good quality CD Recordings on the Cheap, search out Albums recorded with Q Sound embedded in them, there are not too many, but they are able to be discovered for reasonable outlays.
