I had too many of these made, specifically one extra for a loaner tour unit. They’re very nicely made in a solid black aluminum chassis with an on on/off switch and would come with a nice power cable. Since getting it though ive realized that is a bit complicated because there are subtle variations in the kind of plugs used in units this would work for. it works great with the Pi2AES and improves the sound IMO as well as noise of you have any. No extra adapter needed. but the Drop amps I believe would need adapters. And maybe different ones for each unit. This cable is the right size for the RDAC for example but the center pin is the wrong size. So it requires an adapter. Which are super cheap on Amazon like 2$ cheap but figuring it out might be complicated... So I’m just curious if there’s interest for the Pi2AES alone or for use with other units with an adapter.
