The Octava HDSA71 does not have any upsampling or other apodizing filters ... however, the difference I hear between the optical and multichannel input is similar to what crion describes ... looks like HDMI is the 'special sauce'. Perhaps high jitter is good after all? 
Main system - Sources (Kodi-HTPC, Vero 4k, FireTV, Sat) into Trinnov Altitude 32 (8-16) (+Roon), Trinnov Amplitude 8 amp & Vivid Audio (Giya G3, V1.5) and REL Stentor III speakers. Others: F80 + Raspberry Pi and other Pi systems.

Perhaps high jitter is good after all? More likely it is just the opposite. I guess both units use the Silicon Image 9135 HDMI receiver, which is said to have excellent resistance against jitter. Anybody already opened up their HD621?

Yes, Microsoft got it wrong, based on the increasingly prevalent view that "ise" is correct in the UK. Of course, no doubt at some point "ise" will become the official spelling in the UK - language evolves.

F2. I prefer 2 channel FLACs from the HDI Dune BD player regardless whether it uses coax or HDMI. The HTPC triumphed the toslink of the PS3 in the past and some other sources, so it's not a slouch. The HTPC sounded a bit boring and uninvolving in comparison to the HDI BD Network Player. I didn't know PS3 supported FLAC or any lossless music format? Ooops I suppose you could have compared playing one of those flat shinny things you spin, but I tend to forget they even exist. I assume you disabled resampling in PS3 if you did. I find all bitperfect 44.1k PCM sources sound the same through the G68.

If you think listening to music is fun, try learning an instrument.

Actually the PS3(toslink) vs HTPC(coax) was compared as AC3 transports. Material was POTC. I do find a difference on PCM sources into the G68 on coax. I always run soundcards Bitperfect if possible and there are differences IMHO. Better clocks in the source gives the G68 a better time.. Better soundcards give better dynamics and more punch. Weiss Minerva Firewire external card is the best SQ SPIDF sound card I have tried in my system. I think it would give the HDI Dune with HD621 a tough match, though I don't have it on hand as I will not put any money on SPDIF sound cards atm. It's HDMI LPCM audio all the way now  I have dreamed of the SQ of the M 808 from mediaclients/servers and the HD621 put me a bit closer to that goal.
