«You sound like someone advocating spending mucho bucks to solve, what for many would be, an adequate and inexpensive fix.»
You're putting a simple resistance between two devices of 10K , connected by a cable of 2K? perhaps, to solve a problem of incompatibility of gains. It's one more? But all the others do not obey to projects? and very expensives. Considering the investment, is not a serious way to solve the problem. There are some preamplifiers, which have entries with different gains, for digital and analogue, or a switch, to change the gain. This is to face the problem seriously. This makes part of the project. I think 'Amused' was thinking that spending a certain amount of money, everything would be perfect. he deserves your comment, not me.
