One of the potential advantages are life like dynamics. Often, tube output stages will make the drums sound more like what you hear from vinyl.
What are the advantages of tubes in a CD Player?
.....and are they better than solid state CD Players? I have had a few players. Rega Apollo, NAD 542, and a Cambridge Audio (actually a DVD Player). I loved the Apollo, but thought I wanted to go to a complete Computer Audio system so I sold it. Now I am contemplating buying another player. I hear the tube sound is so warm and non-digital sounding, which is why I bought the Apollo, well that and the look of it. So, should I go tubes this time? I was looking at that Raysonic 128 and the Shanling and maybe even the Consonance Droplet
