Tamper Resistant Duplex Outlets

Hospital Grade is not necessarily Tamper Resistant (TR) but they can be found.

Back stabbed outlets should be removed.  Back wired outlets, which are screw tight, are fine.

It is relatively easy to find combo rated "Commercial/Residential" outlets which are both Tamper Resistant and commercial grade with significantly better construction than your average $1 home outlet.

The NEC doesn't care about Hospital Grade but it does care about Tamper Resistant.  If you ever sell your home not having those TR outlets may be something an inspector catches.

For the money, and value, I'd suggest an affordable Commercial/Residential outlet over just about any expensive audio grade outlet. 

That way you are meeting code and don't have to worry about what happens when you move.

On the question of what happens when you move....unless you just bought a new home, your house does not have tamper resistant outlets.  There is no requirement to backfit.  It is very unlikely an inspector will conclude that your audio outlet was installed after the requirement was in place.
