Switching to a Spectral preamp (DMC-30S) from a Sonic Frontiers Line 3 made a significant difference in the two areas that you mention. The Spectral is much faster, more transparent, and very free of distortion. I didn't realize how grainy the sound of the Line 3 was until I replaced it with the Spectral preamp. More significant improvements came when I switched from a Krell FPB-300 amp to a Spectral DMA-150Mk2 amp.
Switching to Spectral components brought significant improvements in resolution, clarity, separation between instruments, and natural accuracy. You should definitely look into a Spectral preamp -- and possibly even a Spectral amp.
