yes that is what I am trying to determine, mostly for the purpose of knowing if the file I would own ( no ripping involved) has a value or if it is basically of no value once I own it.
I am going to answer not as a legal expert but as a devils advocate.
If you buy a download, the value is in the music, and your ability to listen to it in high resolution.
The problem with anything that is digitally transferable is that it is too easy to "cheat." One can sell the content and still keep an identical copy for oneself.
In contrast, even a CD has physical properties that are not digitally transferable - ie: the physical factory pressed "silver" redbook CD. And the factory printed artwork. These may be copied and shared, but copies are not exactly as produced by industry, and thus a copy has less value to a collector than an original. The music may be identical, but some people like the factory produced product. Like people wanting a 45 rpm vinyl disc of a song that is readily available in much better quality. They want the physical version of that song or songs that was factory pressed. Therein lies the value.
With a purely digital release, the same is not true. A copy is exactly the same as the purchased item. Both in audible content and digital artwork if any. Therefore, there is no way to insure that a copy which is sold is not retained by the seller. There is no physical transfer of product. In this way, the person who resells a digital copy could easily become a distributor, rather than a one time seller. In the broader digital arena I suspect any "honor system" is meaningless. Plenty of people are willing to sell what does not belong to them. That's just the world we live in. This is the definition of music piracy.
With DSD I suspect the answer IS down to the honor system. As a user of DSD files you are in a limited marketplace to start, and there may be a sense among users of DSD that it is not cool to file share, because if you undercut the market it will not take long before industry says "screw it" and decides not to offer DSD files for sale.
So your question is, do you own the content and can you resell it? Technically no. Because there is no physical transfer of goods. But selling would be easy to do, and it would be hard to prevent.
So to sum up, a DSD purchaser would look to find the value of such a purchase - not in the "ownership" of that music - but rather in the ability to hear that music in pristine quality. In most cases you can hear the music for free in advance, thereby allowing you to make an informed buying decision, rather than "buying blind" and taking a chance that you will not like the content. So this theory suggests that there would be no need to resell the music you have chosen to purchase in DSD quality. You already knew what you were buying.
This is not a legal opinion. This is not even my opinion. This is just an idea of how I suspect industry looks upon the issue.
Just as a post-script, my understanding is that within the iTunes universe you do not own the right to share or resell your purchased files. Of course people with technical acumen do it, but I am pretty sure that contractually it is forbidden.
I hope this helps.
