People were sharing their experience with the Cool Audio BBDs having less supply voltage range and thus worse signal-to-noise performance. I know that Analog Devices and particularly THAT Corp are excellent quality, so I assume that the Cool Audio VCA might not be as good. No direct experience, though, other than fellow engineers noting that the Cool Audio chips are in the lowest-cost products these days.

I have some of their other cloney chips, but haven't actually gotten around to trying to apply them (e.g. the BBDs, the companders).  The BBDs are definitely low-voltage versions though, the data sheet for the V3205 says 5V operation.....  So you lose headroom....
