I have two Quince sweaters I absolutely love - the fisherman cotton sweater, which is my greatest workhorse sweater, and a linen cardigan. I bought an oversized cable cardigan that is just too big - I should have returned it.
I wouldn't buy cashmere from Quince, that said. The proliferation of cheap, low quality cashmere is a disaster from an animal welfare and environmental perspective. I mean, there is no GOOD overconsumption - but that's a bad place to get a cheap deal.

You can find gently used cashmere on all the resale sites - I'd go that route.
