Drive an audio transformer from an AOP. Good or bad idea?

[mudevilo]

Of course, there is nothing in the academic definition of an opamp that prevents it, or make it particularly suitable to a specific task.
Driving a xfmr implies a few constraints, such as current capability commensurate with the xfmr characteristics and output expectations. Low offset is to be considered, since it can result in doing without teh dreaded output capacitor.

Is it a good idea to do without the last output capacitor before transforming?
Couldn't even the slightest current in the transformer generate noise?

I don't think noise is the issue with dc / transformer ? Tell me if I'm wrong here - not particularly a analogue audio (yes - that's the correct spelling ) tx bod although have used a few in DIY interface boxes and that has worked out well
