To me,the problem with this type of question,is that it is REALLY hard to quantify each person's cable of choice,without some kind of actual MULTI-CABLE shoot-out,in the same system.I,myself,have gone from the Graham IC-30 to the IC-70,with obvious improved results.
My next,and logical question,would be -Do I think moving up to a cable like the Purist Audio Venustas(the Dominus would be too unwieldly,for me)would,again,be a step up?I DO believe that the Phono cable IS an extremely important link,but with the prices of the better stuff it is really hard,and outright dumb,to simply take another Audiogoner's opinion here,no matter how knowledgeable or able to express themselves in print.That being said,there are some fabulous possibilities for furthering a really fine analog rig,by staying open to the likes of better cable links,even if we like what we already paid serious bucks for!!Frustrating hobby,heh?And we used to think Golf was a toughy!!
