Only partially. 😉 That Neutrik is a dinosaur. There are devices like the Quant Asylum QA403 that do much better.
A good modern scope is fine for the other stuff, doesn't need to be 16bit. I'm using a Siglent HD scope for audio, and it works great. The 8bit I had before it was fine too.

As long as you are not interested in noise levels and distortion of the audio amplifier then every cheap 8 bit scope will do.

Exactly. And if you are interested in that, then a device like the QA403 is a better tool for that purpose anyway. Combo of a good scope + good audio analyzer = better than any scope by itself on the market for audio work.

RTB2000 is very fancy, but in it's core basic scope that is expensive.

I think the RTB is good for audio work because of its bode plot feature!
If money is a problem, buy the two channel with 70Mhz, but with bode plot.

RTB2002 is $1840 USD.
RTB-K36 FRA/Bode plot option is $740 USD.
Siglent SDS2204X HD is $2400 with Bode plot function included on a 12bit scope. Or you can get the SDS2104X Plus for $1400 with 10 bit mode and Bode plot function included.
None of those will outperform a dedicated audio analyzer.
R&S is nice, but it's not the best option, especially not if budget is a concern.
