One time trying a phono stage I thought the SDS was the culprit but eventually ruled it out, so count me as having no issues. I do have it placed away from my pre-amp, phono stage and turn table. I believe the manual recommends this.
Regarding the cord....I asked that very question many months ago. Evidently there are some Audiogoners that believe a better cord will make a difference. Search through the threads and you may find that thread. I've not experimented with cords, I still use the stock one.
