The sensitivity of your speakers and power of your amp will also dictate how far you can set the volume.
I agree with Steakster 100%. Cleaning up the AC power and DC power with conditioners and LPS's is where I got the most benefit of clarity and quietness and relaxation. The cables to and from the DAC can contribute to hi frequency hardness. Once the power is cleaned up the differences and effects of cables are much more obvious. I have 2 DAC's and neither sounded good with COAX but that may have been the lower end Kimber Cable I was using. I have invested a bit in USB cables and reclockers and LPS on the reclockers with good results. But like Steakster says eveything in the chain is adding or subtracting the digititus and the results are cumulative. Its probably not one thing.
