Thanks for your humble opinion, also the problem regarding the USB has been made clear by Kingwa that there was afault in the usb interface.

The impressions I have posted are just initial ones,I haven't listened much using the RCA's, will post more on that.

 

I would say that the RCA's play music at a higher dB then the ACSS, will post more soon.

ACSS is dead neutral and precisely reveals the quality of the source.  The RCA channel runs through a set of single channel opamps that can be changed by the user to alter audio characteristics to taste, such as with use of the A-GD discrete opamps.  The OPA604 provided with the C-2 are not particularly good opamps.  A lot has been written concerning the A-GD discrete opamps around HeadFi.

With the k701's and using the gain button i am listening at just past 9 o'clock. perhaps the pics show when i was running them in for a few days using the ayre disc brown noise phase track. had it cranked up a bit....

I have noticed that when the volume is set to minimum,I'am getting music playing from the headphones.

 

Has someone noticed the same thing.

IIRC, the volume control in the ACSS amps is in the current gain stage, not the input, with maximum volume being -0dB and minimum volume being something like -120dB. What this means is that even with the volume at its lowest, there will still be a signal going through.
