Oh and to your question on why a $5K tonearm with a $5K cartridge.
A $5K cartridge usually means the designer has spent extra effort in minimizing problematic resonances and other sources of distortion. Mounting this on a $1K tonearm that itself is subject to all sorts of distortions and resonances is simply throwing this benefit away.
I could go on but that's just one small example of the constant in this hobby how a change in one component often throws up problems elsewhere in the chain
