Well it's not necessary if you're not shooting for the very, very best and trying to push SOTA.If using established means and really not pushing the limits is all one wants, then the push for that last vestage of improvement is a waste of time and money.
For others the 10 percent improvement and learning that comes from pushing to see "what if" we took this idea to the limit is a passion and worthy goal.
We all however benefit from the latter with new technology and learnings that result. These SOTA units also make it possible for each of us to decide for ourselves if that small improvement in fidelity is worth it. Without these efforts many of us would wonder "what if" or "what is possible if" and how much better could a stereo sound? We can know by going to a dealer and hearing.
