So, what for now?…Ferrite snap-on gizmos? A DAC? Reside myself to the fact that the Saturn, although a good CD player, can’t replicate that vinyl analog sound I so like and therefore buy a TT?
Yes, there are intrinsic differences between digital and analog. So if you prefer the sound of vinyl to cd, and barring any solvable problems in your system, you'll need to go the vinyl route for the sound you prefer.
I am one of the few who prefers digital, at least with my setup, enough to sell off my vinyl collection. I'm not going to suggest any equipment changes as your rig sounds pretty digital friendly. There are many here who love their vinyl rigs and feel digital can never match analog. Give the tt a try and see how that works for you. Maybe you'll join their ranks.
