listen, I won't repeat again:
live value retail has the header for creative digital i/o board, so also good for hoontech (hoontech especially makes those board for live value mainly, because live already has a spdif board)
the difference is live value retail has fewer pin on the header than live,
so if you buy creative digital i/o board, you won't get all the features as from live.
live value oem variants may not have that, check the real thing before purchase if you want to buy the oem.
