DAC Recommendations In 4k Range Used

I've been enjoying my Yiggy with the Aurender n100h and will eventually upgrade. Looking for something in the $4k range used. I have no use for a preamp as I go to my Luxman 509X though it wouldn't be a deal breaker. I listen to classical and acoustic jazz mostly followed by all the other genres .Should I save up for the T+A DAC 200 that you folks praise?  Qobuz and radio are my sources.I appreciate your input as usual. Thanks.
