With modern gear - and I mean that made in the last five years or thereabouts, you could say the DACs sound the same - I mean the CHIPS! What will affect the sonics is the power supply and any analogue output buffer fitted. The fact that many domestic CD players have in the past been very inferior to pro DACs often costing thousands, makes me wonder if some penny-pinching or just plain incompetance isn't to blame why domestic players of old sound so different?
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
