I did consider the smaller version of that earlier in this thread, but was tabled when it was mentioned that even on the lowest switching threshold setting, there might be some inconsistencies in the performance (posts #3 and #4, for reference).
If you are able to confirm that you've not encountered any issues, then I would put it back on the table for consideration. I think a potential workaround would be to use the TV as the control device (setting the threshold to high for TVs, as per the manual), and I can program the on/off sequence timing in my Sofabaton to have the Flex turn on first before the TV, and power off after the TV (which should eliminate the more audible pop that happens when the Flex is shut off before the amp).
