The results speak for themselves. The AV2000 kit is the fastest AV2 powerline adapter we've seen on the channel, but not by much.
The AV1300 results we're just 15Mbps slower, but with a single Gigabit port vs. the two Gigabit ports on the AV2000 kit, the AV2000 kit has an ace up its sleeve. Though this won't improve speeds (as Gigabit Ethernet is the limiting factor) but the ability to connect an additional device to the adapter is a positive.
