I have RECS80 codes for a Classe pre-amp working with a MX-800. It is a different remote and a different device, but thought I would post this just in case it helps.

For system (device) 1, command 16, I use

0000 0074 0000 000C 0008 00FE 0008 00B6 0008 00FE 0008 00FE 0008 00FE 0008 00B6 0008 00FE 0008 00B6 0008 00B6 0008 00B6 0008 00B6 0008 048F

I used ProntoEdit and Universal Browser to get it into the MX-800. The original code came from Classe and I have used it to generate commands that they did not provide.

I use an unused command (command 48 in my case) before each command in a macro to do the toggle part. That way I do not need toggle versions of each command. Works for my Classe.

Not sure if this helps or not.
