Great review Glenncol,
I got a AUSID when I bought my Fuji about 3 months ago. I was a bit worried caus it cost my $1k and I couldn't find any reviews/info (just check there web-page) on them anywhere...but I stuck with because IMO, PQ and SQ were better than others on offer at that time.
I have had a couple of 'issues'. If I did not change channel for over an hour, the sound would start clipping, a little to start, but if I didn't do anything eventually the sound was gone. If I changed channel the sound would come back...very weird.
I checked everything and it was the box. Took it back to HN very displeased. They swore that they had not any issues with the box, however swapped my box for a another, no problems (Thanks Peter, HN @ TVL).
It may have been my imagination, but the SQ with the replacement box sounded my dynamic.
The other issue, the colours would change for no reason and because of above I blamed the box. This had nothing to do with the AUSID box, my fault for using cheap component cables with poor shielding (interference). Changed all three to Neotech, beautiful...
I am very happy with the AUSID box and Fuji combo.
