I am waiting for my H9000, and will be wanting to get an AES snake that works with my Lynx Aurora Digital Inputs.  I believe the Lynx uses Yamaha, not Tascam format will the hosa cable still work?

Yes, but you must remember: if you want to connect a Tascam-pinout AES3 DB25 device to a Yamaha-pinout AES3 DB25 device using those Hosa snakes, you will need one Tascam snake (AES-803T) and one Yamaha snake (AES-805Y). You'll plug the AES-803T DB25 connector into the H9000, the AES-805Y DB25 connector into the Yamaha-pinout device, and connect the input and output XLRs together.

Alternatively, there are also "crossover Yamaha to Tascam" AES3 DB25-to-DB25 cables available without the XLR breakouts.
