For non-fatiguing sound and absence of upper end brightness you might want to try some of the less expensive cables in the Purist line.
Warm sounding cables - non fatiguing
Any suggestions on reasonably priced cables which are non - fatiguing (not bright or overly detailed particularly in the upper frequency regions). Currently using tubes with Millersound cables but sound is a tad bright -- anyone else had this experience with Millersound (similar to JPS).
