I am still very new to most of this audio stuff. Thus far, I've been under the impression that a balanced cable needs to be a dual entry cable, ie Meze 99, Hifiman, etc. This morning I came across a single ended cable on ebay. It's 2.5mm to 3.5mm trrs balanced. I have an Opus #1s that I'd like to take advantage of the balanced circuit, but always thought it would only work with my 58X and 99 Classics. After some research, I did find some information regarding single channel balanced cables. The cable is inexpensive, so that's good, but I just want to make sure this is an actual, accurate thing before I buy and try. The last thing I want is to mess up any of my equipment.
