This is slightly off topic, but thought you might be interested.
I used to own a IC 50. Then went to a Hovland, now a Purist Venustas (which is still breaking in).
The Graham was din to RCA. The others din to XLR. my phono stage performs a little better in my system running balanced.
Who knows if any of these cables were really broken in using my Lyra Helicon to drive it. Also, I'm using a SME 20/2 table with SME IV.Vi arm. I realize if you're using a Graham arm, you may get some better synergy given the internal arm cable is similar.
Caveats aside, I thought the Graham was wonderfully detailed, but thin in my system. The Hovland, much more warmth, slight less detail.
The Purist handily surpases both. In every area I can think of. It only has 150 hours playing time on it. It's still opening up.
If cost isn't a object consider the Purist. If you need a touch of warmth, then the Hovland. If detail is important, and your system isn't slightly thin in the mids, the Graham was good.
