I still personally use the same cables you do. My offerings are a result of people asking for it and saying things like "Well so and so has cryoed up super fantastic wires and such... why don't you offer such things? So and so's are clearly better...." So that is why you see some of the products you do.
As to why the litz braid for the ICs. That is simply because I am currently using the same wire that is used in the headphone cables. Not until I find it worthwhile will go have it made into a cable instead of using the wire from the other. Either way that wont change much of anything other than appearance to a minimal effect.
Lastly, I am not going to make up unfounded biased marketing BS like every other site. I could tell you how they cure cancer and aids or how they help you catch leprechauns but I will leave that up to you to decide on your own. I am just going to give you the cold hard facts.
I wish your $100 was still that... costs of raw materials have gone way up as has shipping.
