Today I received a 75 Ohm Canare LV-61S with Neutrik Rear Twist BNC Connector today. I had ordered this before reporting the testing with my Audience Studio One.
As I now have had several days listening experience with all these BNC cables, I went back and did a rapid A/B test. Had 2 songs playing back to back (Magnetic Fields, "San Francisco" and "The Luckiest Guy on the Lower East Side" from 69 Love Songs), swapped cable and repeated.
The 50 Ohm Canare L3D2V and (Amazon) Eightwood BNC were terrible. The bass was vague and ill defined, flabby, boomy and out of control. I feel I can honestly call it bad now that I'm comparing it to a high dollar cable. In isolation, it might pass for OK, as I myself had noted earlier.
The 75 Ohm Canare LV-61s was pretty good considering its price. I would consider it an acceptable basic cable, it does nothing great, but nothing wrong. That said, I have a feeling the Neutrik connector is a contributing part of the improvement. Its got a very positive tight vise-like engagement whereas the Canare was a good fit, but not as confidence inspiring as the Neutrik.
No contest. The Audience Studio One BNC keeps the clock signal in firm control. Because of this details are in tight focus. The bass definition and everything sounds for lack of a better word, "mature". So good.
