As I have just made the plunge for an 861v6 (who needs two kidneys anyway!) this is interesting. I currently have my v4 going through the HD621 to get apodizing. I am also able to play 176.4 and 192 Khz files (albeit downsampled) with no problem and multichannel files (granted the only multichannel files I have are some demos I downladed from Itrax.) If I go from the PC directly into the v6 will it still downsample the 176.4 and 192 Khz files? And as for multichannel I haven't found a sound card that outputs 3 digital RCA connections for the 861. I'll probably leave both connections to compare and for the rare multichannel or super hi res file I can use the HD621. Hopefully the 861v6 will support up to 192 Khz in the future.

Thanks,
John
