Not sure why you’re posting this - I’m confident that you can dig around on manufacturer’s web sites just as easily as we can.
If you’re happy with the Yamaha, then go on their website to see which models newer than the 3800 have HDMI 2 and RCA outputs, then go look for one of them used. Yamaha’s website carries info on both current and past models (as do most other manufacturers) so it should be pretty easy.
For a prospective used Yamaha model, find out what its list price was, and that would be a starting point for past models from other manufacturers. I doubt there’s much difference between one DAC and the next, except perhaps for those in the cheapest and most expensive models.
