@inna it depends...
For example, the Clearaudio Concept Signature turntable with Tracer tonearm is in the $5k range or so. It’s the real deal. I wouldn’t hesitate to put a $4k cartridge on it, like a Hanna Umami Red, Dynavector Te Kaitora Rua or a Lyra Kleos. The table and arm are that good they can take advantage of it (and I already know Clearaudio arms work really well with DV and Lyra).
Synergy trumps trying to generalize about cost balance. I just think trying to do the latter is futile and can lead to sub-optimal or unhappy combinations.
