My K3 speaker performs flawlessly and puts out wonderful audio until NR is turned on. It then produces some shrill resonances at some frequencies. I find these resonances disappear when using NR on external speakers. I owe an apology to Lyle Johnson for blaming the problem on noise reduction parameters.
