You are not going to make a purse out of a sows ear. The Sonos has relatively high jitter compared to the other alternatives. The jitter of the digital source is #1 importance. No DAC is going to fix this, although some upsampler DACs may improve it a little.
I would recommend to either replace the Sonos with Logitech Touch, reclock the Sonos with a good reclocker or get the Sonos modded to improve the jitter.
Then think about a good DAC.
