I replaced 1/4” TRS cables with molded plugs between my Focusrite audio interface and powered monitors. The quality of the Monoprice cables appears to be very good, especially for the price. I may have noticed that the highs were a bit better than it was with the molded plug cables. Noise levels were about the same (negligible). The main thing I like is that I was able to purchase the Monoprice cables in lengths that were more appropriate for my set up (1.5 and 3 foot) instead of the previous 5 foot cables for a much cleaner setup. It doesn’t hurt that the cables were less than $5 apiece.
