Better DAC then DA1 module in McIntosh C49 without braking the bank.

I got to the point in my system, when my DA1 DAC module in a McIntosh C49 preamp is the bottleneck. 

In comparison to my vinyl, CDs, files and streaming sounds flat and unremarkable. 

I have an SMSL SU-9 dac but it's worse than the one in Mac.

My system consists of Legacy Audio Focus HD speakers, McIntosh MC352 amp, McIntosh C49 preamp, McIntosh MB20 Bluetooth transceiver, Rotel RCD-1572, pc as a streamer and file player through Foobar2000. CD player is connected to the DAC too though coax.

DAC need to be able to do DSD, have USB, and connect via balanced. 

I like the DAC sound signature to be as natural as possible.
