Big loop gain vs. big bandwidth
If you want a amp with low distortion, look at the distortion numbers.  It shouldn't matter to you how that is achieved under the hood, only that it is.

There are all kinds of ways to trade off parameters in a audio amplifier.  Taking one or two parameters in isolation doesn't mean anything.  Look at the result, not the method.

That said, simply using large open loop gain, then global feedback to fix everything, isn't how it's generally done.  The problem is that such a system tends to suffer from TIM (transient intermodulation distortion).  The better systems tend to use some local feedback in each stage, with the overall open loop gain not wildly above the desired closed loop gain.  Then moderate application of negative feedback keeps the closed loop gain predictable and the frequency response flat.

Again though, measure results, not how they were achieved.  There is more than one way to design good audio amplifiers.
