3.5mm to RCA cable suggestions.

Here is the 3.5mm/TRS also:

The same comments I had about XLR vs. RCA apply to the Kirlin 3.5 mm to dual TS (not TRS) cable linked to above, vs. RCA. Also, I’ve never liked 1/4 inch connectors because in my experience the contact they make can sometimes become intermittent, especially if they happen to be jiggled.

Excellent point on the TS jacks AL.

Just a side question...is there any advantage to upgrading power cords on powered monitors at this level? I was thinking something like Pangea AC 14SE MKII.

Thanks again for taking the time to offer your experienced help.

You're welcome, Asahitoro.  Regarding whether or not a power cord upgrade may benefit this particular speaker, though, I have no idea.  In addition to depending on the design of the speaker's two internal class AB amplifiers, and on the characteristics of its stock power cord, it could conceivably also depend on what the AC line voltage happens to be at your particular location.

Good luck.  Regards,
