It turns out that in the application being discussed, namely a unity
gain buffer with output of 2 volts into a 10k load, even a 741 would
probably sound good.

FWIW More years ago that I care to remember a friend of mine bought his
first 'serious' hifi system. He had more money than I, so did this long
before I could afford anything comperable. He bought a QUAD system
33/303/ESLs. But wanted more control over the frequency response.

So I made him some simple 'bass shelf' tone controls ... using 741s.[1]
They actually worked quite decently well. He happily used the added
controls for many years. So yes, they actually sounded fine in the
circumstances, despite having zero 'street cred'. 8-]

That said, latterly I'd always automatically use better op amps since -
like using something like a Meridian DAC - they help give confidence that
you won't have any problems with the performance envelope. :-)

[1] IIRC The circuit was from a HFN of the era. Which I think also used
741s as this was in days before even TL071's, etc.
