Any USB cable that (really) meets the USB spec. and makes a good connection will be as good as any other. It should cost a lot less than $100. Your friend is smart.
Now, if there is an issue with noise (perhaps causing jitter) you will want to do some isolation, but that is not the cable.
There is a thing called the Iso Regen that costs a bit over $300 you can google. It's claims are not well-supported by listening tests or electronic measurements (it is a new device I think) BUT you can try it for 30 days and then return it.
