Rob, I agree completely. Many audiophiles have their SB's modified so
that the analog signal goes out directly from the DAC. This inverts
polarity. As a result, many of us are still sitting on 6.2.1 with V15
firmware (that also inverted polarity) and remedied the problem.
However, this means that we don't get all the bug fixes. We can't just
remedy the problem by swapping the speaker wires at the terminals as
this inverts polarity for ALL sources in the system. Also, the vast
majority of pre-amps do not have a polarity inversion switch.

So a simple software switch "Invert polarity - Yes/No" via SlimServer
interface would at least get us back to having all sources in correct
polarity. The ability to switch polarity on the fly via the remote
control would be nice but could wait until later.
