I'm using the Dark Lord cable just now, I'd say part of your earlier description of the other cable also applys to the Dark Lord, ie;
"I found will lessen bass quantity a touch though provides better texture, soundstage widens and you will gain a slightly brighter / crisper TF10."
Although the bass quantity is perhaps slightly reduced I think it is an improvement overall, brighter, crisper and a wider soundstage sums it up well Imo... and I could always just EQ more bass in if I wanted to. I really like it and prefer it to the stock cable for the sound sig as well as the cables physical characteristics. Although the standard cable has less microphonics, it is just far too stiff.
hmm i'm using a Zune HD so I dont have EQ unfortunately.
I listen to electronic music mostly and usually listen to it on my KRK studio monitors and Sub at home, plays well with strong and clear low freq. I find the TF10's are a little light on the low freq though they are super clear and wide, i'd prefer to have a stronger low end than make it wider.
is it really a noticeable difference in it or very slight?
