The DV-59AVi and DV-79AVi are great choices for iLink. That way you can utilize the PQLS function as well.
They may be difficult to find, but well worth the effort.
(I have both hooked up to my SC-09TX)
Very nice looking receiver, BTW, grassy

From the
VSX-AX10Ai-G manual

i.LINK digital interfaceThe i.LINK interface makes it possible to connect this
receiver to i.LINK-equipped components, allowing you to
enjoy high sampling rate (up to 192kHz) PCM
multichannel digital audio from DVD-Audio and SACD
discs, as well as digital audio from DVD-Video, CD and
Video CD discs, all with a single cable.
Page 83 offers additional information.
Hope that helps.
