But I did not notice one thing until it arrived: the manufacturer specifies a "preferred" direction the cable should be used, which happens to be the opposite to my usage (the cable is RCA->TRS, my usage is TRS->RCA). I wanted to ask you, the headphone enthusiasts here, whether you THINK or not that there is or could be any noticeable or measurable difference between the directions the cable is connected (in sound). I don't have the appropriate adapters to try it myself, so I cannot experiment with it. My opinion is that the cable is too short for any "crystal alignment" to make any sound difference (btw 30cm is about 12 inches)... And if there could be a difference, are there any symptoms I should look for in the sound? I use the NOVO to feed my HD650's and AH-D2000's, and the sound is just orgasmic, but I have never heard anything different (talking about hi-end), so maybe I think that it's good just because I don't know anything better. Is this a legitimate concern or am I just paranoid?
BTW this is the product page for the cable on the manufacturer's web:
Proel Die Hard DH630
and this is their site with info on "cable's direction":
thanks in advance for your opinions!
