Resurrecting this discussion

Found this thread from ages ago and am properly triggered by it.

My feeling is that the PGA2500 is a scourge. 5 volt mic preamps with no headroom and are found in 90% of the USB interfaces people buy. Sure - they are "clean", boring ICs that you can plop down on any product and be done with your analogue stages. How nice if you only care about making USB-powered cheap interfaces.

But OP saying this:
"Discrete designs just can't keep up with the ever evolving semiconductors. "

10 years after his post - our Camden 500 is a completely discrete analogue circuit that absolutely trounces any IC-based preamp - especially the PGA2500.
