I went on quite a journey looking for a better sounding CD player. Then I remembered I do have a few SACDs, and now used SACDs are inexpensive, so I narrowed the choice to CD/SACD players.
I don't stream, so external DAC, versatile inputs are of no interest to me.
It became clear to me that is is the combo of transport, processor, filters, over-clocking, IOW, it is a salad of many parts that give the final sound.
I ended up buying and loving the sound of a used Sony XA-5400 ES. The lasers do get old/weak, so any used one, find out the approximate hours of use. Also, are parts available for that model, do a simple search on hifishark for units and parts.
My Quest, with help here, a long read, but much discovered along the way. It may be helpful to you when finalizing on a different unit.
