Yeah, I love Opus..still have a 150DC power supply on the shelf that I bought from them in 2003, and still works flawlessly. Haven't kept up in this connector space, but I do see that those adapters are plentiful, so looks like no issue at all.
Question: do you run standby? do you use the cut-off voltage? I'm a bit concerned about it, see what I'm trying to do here: ...I have a deep cycle battery and love the 'dead man timer' option on the Carnetix, but don't think what I propose in that thread is a good idea after all, and am looking to get the Opus 320 and rely on the low voltage shut off. Any experience?
