Hi, Georg.
Yes, as Kjell and Helmut have described in a separate message, it is
possible, with modification. My reply was to point out that the DC signal is
not usable, as currently configured.

I imagine that others who have use Hermes with an external amp may have also
used Alex as the filter bank. Perhaps they will share details of how they
may have modified Alex for the PureSignal feedback loop.
