Thank you for your detailed suggestions. Some of the suggestions have been
already implemented:

- pin headers for default inputs connected to the switching contacts of the
sockets (for default connections)
- pin headers for expansion of the rows
- pin headers for expansion of the columns

But I don't think that we will offer head phone amplifiers or meters. We
already had similar modules available (A-139, A-197) but discontinued them
because of the poor sales.

Best wishes
