I have an ADA8000 which did its job really well for a couple of years. I actually preferred it to a couple of other similar units I tried, and especially at 150 quid I paid for it, was really useful. Had it as part of my mobile rig for that time, with a motu 828
It has now however given up, after just a couple of years which is dissapointing. Still, it has already earned its money several times over.
Surprisingly good unit. shame it couldn't last longer. I would consider buying another if I was in a corner and couldn't afford an RME octamic, which may be my next choice.
