The problem I had was that the Music Metre Silver phono cable had a loosely wrapped shield. Music Metre preferred unshielded for their silver cables, but with my set up and all the power supplies it was picking up too much hum.
The Harmonic Technology was not shielded well enough, it had a low level hum. Also, the musical presentation of the Harmonic Tech was not quite right to my ear. It seemed a bit bright.
The Graham IC-70 was very well shielded but seemed to be a bit soft or muted. It could have been a break-in issue, but that cable just did not do it for me musically.
I found a 2m Nordost Quattro Fil. It turned out to be the quietest of the bunch. The shielding completely eliminated the hum. Also, it was the most musical phono cable. Sweet highs and rich mid-range. The bass is really extended and tight.
I am going to sell that Quattro Fil, having just recently upgraded to the new Nordost Tyr phono cable. It takes everything the Quattro Fil did up a couple levels. More bocy on the sound, way more ambient detail (without sounding detailed or etched at all).
Alas, I have never heard the Purist Venustas, but have read a lot of good things about it.
Enjoy the music!!
