The primary differences between the A-100 and the A-100 appear to be:
- HDMI 1.3a support: i.e. additional audio codec pass-through support
- SATA HD support: much better than IDE in the A-100
- Optical SPDIF instead of coax SPDIF: not much difference to me- my receiver can assign either.
I contacted sales and they can cancel my A-100 order so I can place an order for one of the other units, but there are no details on shipping at this time- so it could be a week or it could be six months!
Since this model is brand new (read: public beta) I think I will stay with the A-100 until there are a few firmware updates (the A-100 has gone through 7 firmware releases since November of last year). My only concern with the A-100 is that it will soon be phased out as the A-110 is almost a direct replacement...
