Jriggy, yes. my measurements showed a peak exactly at 5-6 khz.
to my ears, that made the graham bit tiresome to listen to and eventually bothersome
my measurements also showed a BBC 4db dip between 1.7khz to 3khz.
I still liked the graham ls5/9, but the shl5plus are more align with my preference. but I could have been very happy with the graham as well
