in my travels through several dozens of dacs since 2020, i would say there is definitely more variation in s.q. among lower priced dacs, as each are making cost-driven tradeoffs in the various elements that affect sonic performance and trading them off against features, ultimate retail selling price etc etc
more expensive dacs (good ones $6-7-8-9 grand and up) tend to converge in sound quality i m e - one exception to this is are some well renowned pricey dacs with vacuum tube output stages and rectification... those can sound notably tubey, an overt design choice...
usual caveats and contextual points apply, your system needs to be revealing enough, you need to have a good clean digital in-feed, etc etc...
and yes, as others have said, all aspects of the dac affect the sound, not just the actual d/a conversion mechanism/chip/ladder what have you... search my old posts on the subject, won’t repeat here
