Is there a better DAC than the Schiit Bifrost for $300?

I have a Schiit Modi 2 Uber as my DAC. I'm not completely dissatisfied with it but understand that it is low end and that there must be room for improvement. I've got a nice older system but I'm not a fanatic about SQ (yet). I could use the Modi elsewhere or sell it...although Schiit just came out with the Modi 3 so the Modi 2 Uber is only worth about $60-$70 now.

There are open box Bifrosts on eBay for around $330. They are $400 new.

My questions are:

Should I see noticeable improvement going from the Modi 2 to the Bifrost?
What if I just went to a Modi 2 Multibit at $250 new, $200 used?
Is there another DAC I should consider in the $250-$300 range?
