Expanding on my original post and adding to the perplexity, I bought my KN6 a few months after they were introduced and the lag was immediately apparent. I wrote to Technics and was told that update 4 would cure the problem, so pretty obviously the existent of a fault was known by Technics. This up date certainly made a considerable improvement but still an intermittent delay, and always a delay when playing an E flat chord. I hoped that updating my 6000 with the EW65 card would finally effect a cure, but no joy.
When I raised the matter on the other site several people appeared to have the same problem. The delay occurs with both preset and floppy styles.
One other and possibly related (?) thing is that playing any ninth chord using APC always results in a non related and total dischord. This too was raised on the other site and one or two other folk had a similar happening. Letters etc to Technics have so far resulted in nil replies. They're not proving these days to be exactly user friendly folk.......
