Sorry, I think that I what I said above may have been unclear. What I'm trying to say, in short, is that if you are putting yourself through all of this, modding your SBT and such, with the intention of streaming high res from a streaming service, you are wasting your time.
The only way that you are going to realize the benefits of the mod to the SBT is if you have hi res files of greater than 16 bit words lengths and greater than a 96khz sampling rates. The only convenient way that I know of to come by these files is to buy them from a service such as HDTracks at a cost of ~$18 per album.
Of course, if you know something that I don't and there is a streaming service that streams 26/96 and greater files, please share. My wallet will thank you.
