So I have been experimenting with phono cables lately:
1) Nordost XLR Valhalla: Had to twist the two cables around each other to remove hum. MUCH worse in this system than my Tyr: slow, a bit recessed, uninvolving, though deeper bass
2) Shunyata XLR Zitron Python: unable to tame hum, very clean at lower volumes; may be a winner in a system with RCAs; contemplating getting a VPI RCA junction box to give it another chance
3) Nordost XLR Tyr 2: MUCH less susceptible to hum than the Valhalla. No surprise, I picked the original Tyr because it was the best shielded cable in their line; still is save for the Odin. This cable also has a MUCH lower inductance than the original and any other Nordost cable, as per their site. This really shows with massed or solo violins and other high-frequency instruments. The bass with this cable is much deeper than the original Tyr - low organ notes are rendered with aplomb. It feels like there is a lot less signal loss over its predecessor. Interestingly enough, there is no official Tyr 2 phono cable ?!?
Yet, there is still something missing, and it's really the truth of timbre and things like ultimate vocal articulation that the 50ic brings into the game on the DAC - a crispness that's illuminating with the MIT. Alas, there is no Matrix phono - don't know why. Frankly, the only cable in this collection that comes close to the MIT in that regard is the Python, but I just can't get it to play nicely with hum. I wanted to try the MIT MA-X phono, but it don't come balanced, ugh!
Still exploring... what needs to be done here is replace both cables in and out of the phono stage at the same time...
