Digital Playback Quality can be summed up in 1 sentence after 30 years:

There are only 2 Designs out there, those which produce Headache and those you can bear for more than 10 minutes.

Price has no influence.
Eugene makes a revelant point. If you are using an inexpensive active preamp, then all bets are off. The distortion, noise and compression caused by this will undoubtedly mask the differences between most DACs.

Replace that thing with a good transformer passive linestage and you will begin to hear the live music.

The digital source jitter is critically important. If you are using an inexpensive CD transport to drive the DAC, this will kill the SQ from the start. Replace it with a more expensive low-jitter transport or with a good computer audio source with low-jitter.

This is like buying a $10 turntable and tonearm and then putting a $100 cartridge on it.
