John (and Chris)

I was not thinking that only the DAC chip per say might have caused the difference but also the rest of the circuitry. I made sure thought that the volume level was the same (because I also experienced what Chris described very well). What do you guys think about the quality of the power supply and its ability to keep the current constant (whatever the electronic component, amp , preamp, processors etc...)?

P.S. Well you don't have to answer if my questions are bugging you.
