Here is my system. I just basically wanted to know how the build quality and sound is. If this helps you out, here you go. Thanks AMC 1100 preamp (replacing this) AMC 2100 amp Pioneer DV-414 DVD/CD Sony MDS-JE510 MD Musical Fidelity X-Act dac Magnepan MMG or Paradigm Mini Monitor (used for college) Paradigm PDR-10 subwoofer Monster M-550i interconnects Transparent coax digital Audioquest OPT-1 toslonk digital Audioquest Crystal II speaker cable I know the sources aren't great, but I do notice a improvment with the dac in place. My problem is that the Paradigms especially are a little bright, and I really like tube sound overall anyway. Thanks
