All jokes aside, going from one sub-$200 cable to another will get you very little ROI if any at all.
Thanks. That's what I figured, and why I felt that the nice advice I got from Audience directly was really just a way to get me into their products but not really likely to change much about what I was hearing. I'm looking at used prices for the model you mentioned, and it's probably something I could do.
Of course, if I aim to put these on the mono blocks, the cost doubles, if I can find two of them.
Perhaps just get one and either try it on my solid state stereo amp? Or on an upstream component, such as the DAC?
