Could it be the AFX function is on? This adds a bit of delay between L
and R. In using a pair of non-amplified external speakers connected
to the rear SPKRS jack, I don't notice any objectionable echo when NR is
engaged. The setting which I use for SSB is NRmF5--1. This is mixed
audio being part original audio and part being DSP audio.
