Yes I agree, I don't think my system is resolving enough, perhaps even less resolving than a 3000 usd system as you have alluded to, hence I am not hearing any benefits of these so called high end usb cables (not that I tried any more expensive than say $200). I apologize if my original post offended FM's with high resolution systems like yourself. The wireworld platinum is a super cable ($700 almost 50k INR), I don't think I can afford it, and even if I did I don't think there will be any difference to notice in my inferior setup or my novice listening skills. I haven't heard it or any shunyata, so I will take your word for it that it is a better usb cable than any shunyata any day. I am going to stick to $100-$200 cables. As you mentioned one should budget cables based on a percentage of the total system cost, not on what they hear. This is certainly not the right way to do it, trying to hear if a cable makes any difference without considering the cost of the system it was placed into - typical newbie mistake. Forgive me.
Cheers,
