THNX @JPK, much appreciated!
My particular build is integrated in a touring rig that ends up plugged into the power networks of many poorly regulated venues. It will also be subject to much more external radiation than would be typical in a studio or desktop deployment, so I am looking for any components in the BOM for which I can provide alternates that will help keep the noise floor as low as possible. Cost isn't really a concern.
I mentioned the resistors because I have many alternates in stock - any other alternative component suggestion?
Thanks again!
