DAC recommendation

At the price point you've specified and if you remain unsure after reading other recommendations in this discussion, an Audioquest DragonFly Red will set you back around $200. Plus, it's highly portable (about the size of a USB thumb drive) so if/when you get something more refined/sophisticated, you can use the DragonFly with your phone or laptop. It's been favorably reviewed by several experts. Audioquest also releases free firmware upgrades and the Red does the second MQA unfolding, too.

I am currently testing the Mimby but I will have to caution you. If you are connecting via USB then plan on the purchase the Wyrd-- they call it the USB Decrapifier. It sells for $99. I have an iFi iPurifer2 and we heard a noticable improvement when it's Active Noise Cancellation. Wanting to stay true to Schiit, I asked to test the Mimby with the Wyrd. The combo is worth the additional cost. It was good, just the Mimby. But with the Wyrd it is Outstanding. If you are using toslink or S/PDIF, the Mimby will get already have solved the USB noise issue.

IMO if you are going from the RA CD 50 to a $300 DAC is not that big of an improvement.  Just get that CDP modified.  You will save on the DAC and a digital cable.  Happy Listening.

Yeah not really looking to upgrade the CD player, rather looking for a DAC that would make Tidal and FLACs sound equally musical and engaging.  And wondering if that exists for $300, new or used...

What's the skinny on all the Musical Fidelity DACs up on A'gon?
