I have two adapters. So the relevant numbers are in the 1 - 0 and 0 - 1 parts of the matrix. They show the physical sync speed of the devices, up and downstream. Obviously, 0 - 0 and 1 - 1 is meaningless in this context, so just ignore those numbers. If you look at the 1 - 0 you will see 3478, which is the physical sync speed, so 3.4Gbps

I'm guessing with sync speeds like this, it's going to be worth my while to upgrade my WF-803Ms to the MA2500D. Can you give any indication as to the price of the new MA2500D?
