I disassembled a very fancy Pioneer Elite
preamp, and found 5532 outputs.

A properly used 5532 is able to swing ± 13 V on a 2 K load with a typical
±
15 V supply voltage...

The power supply was really tiny, using the
78XX regulators in TO-92 package.

At 8 mA of supply current per OP amp and 100 mA of available output
current
per 78XX or 79XXin TO-92 form why should you need anything larger?

IME, 2K is not adequate for more than short runs.
