Does Fosi have any products with input auto sense? I have 2 large, antique radio cabinets I wat to "retrofit" but avoid having to use clunky manual remotes or a kludged method to turn it on/off.
Is it OK to replace the 2 XLR OpAmps with SparkoS Labs SS3602 and the remaining 2 (sub and Line Out) with OPA2134PA?
Any potential issues or downsides?
