Which unit is this about?

Hi Paul,

on that unit switching between speakers involves the front headphone outputs. For safety reasons (and possible sueing in countries like the US) we will not add such an option, sorry.

I know that there exists companies that produce headphone amps with 5 and more watts output, completely unprotected, capable of quickly damaging ears and equipment. Most of these only dare to sell these amps because they are not reachable by US jurisdiction (some might just be stupid and completely ignore the danger). I wrote a lot about all the thoughts that went into the ADI's in the manual. Producing such a powerful amp and selling it world-wide made us add as many schemes as possible, so if we would ever be drawn to court we could easily explain that we are the best and most protected and ideal (in this regard) of any existing headphone amp, and that we exceed the existing 'industry standard' by far.

The ADI-2/4 Pro SE can have its rear TRS outputs switched to 3/4. With this option active and disabling the phones outputs such a 'quick switch for speakers' option would be possible. I'll add that to the list.
