You should keep in mind that you'll likely need a bunch more
swing from the preamp to drive the amp to clipping. This, since you'll be providing 1/2 the p-p voltage swing from the
single ended output. Often, that's not an issue.
The balance of the input circuit can be a minor issue, as
some of the "balanced" inputs are not actually "balanced"-
they are only + & - phase, with different impedances. This,
since the " - " input is often also the node of a diff pair
that gets the *feedback* from the output, and is usually quite
a bit lower in impedance than is the usual " + " or non-
inverting input.As much or more than a full order of magnitude lower in impedance. So, you'd want to be sure
to drive the non-inverting input, given a choice. The other
usually gets grounded.
As mentioned, the common mode noise rejection will be lower,
more like a "regular" amp.
Other than that, it should work ok.
