I am planning on buying a small studio setup soon using a G4 with a Yamaha 01V digital desk. I have decided to connect the two using the optional ADAT interface and was wondering if anyone could tell me whether the RME hammerfall would be a decent card to use for this purpose.
I had previously considered using a MOTU 2408 or a Digi oo1 but I do not require the additional analouge inputs or the AES/EBU ones so I thought it was pointless to spend all that extra cash.
I hear that the Hammerfall has extremely low latency (around 1.5ms at best) is this true? If you can think of a reasonably priced interface or card that would suit my ADAT needs then let me know.

For my money (although i'm sure some one will disagree) the Hammerfall is THE best Adat card available .
GO a head buy it! although from your description you could get away with the LE version, as it has fewer adat ports its cheaper, and expandable if required later.
