Upgrade Question

So, I’m a dyed-in-the-wool, old school, CD guy. Not interested in vinyl or streaming. I have currently a Musical Fidelity 3D CD player that I bought new in 2003. I love the sound of it, but realize that technological advancements in the medium may warrant an upgrade in players, amd the unit may be getting old in the tooth. I’m looking for a one box solution. In addition to the MF, my system consists of a BAT 225se power amp, BAT VK-3i preamp, and Joseph Audio Pulsars (v1). Your recommendations would be most appreciated. Thanks.
