How I tamed digital glare.

For months I have been trying to eliminate digital glare in the my system, which showed up most noticably in the upper middle frequency vocal range, especially female vocals. I tamed some by replacing the stock fuse in my dac with HifiTuning Supreme Cu on the sage advice of Chris Van Haus of VH Audio, resulting in a significant improvement in tonal density, detail and clarity. So far, so good. Today I lightly dusted the laser lens in my CEC transport with a microfiber cloth and was astonished to discover a substantial improvement! And the laser lens and drive compartment appeared clean to begin with (in a smoke free environment). I tried cleaning contacts, swapping power cords and interconnects, rolling the tube in my MHDT dac, and so forth, but this simple protocol was more effective than any of those experiments. I suppose results may vary as every system is unique, but for me this simple tweak was revelatory: greater clarity and a signifcant reducton of hash. Wish I had thought of tt in the beginning; it would have saved me considerable time and frustration.
There's more to life than this silly hobby and if other facets of life spill into it, that can be a good thing.

It is actually "pathetic" that people would come hear to an anonymous audio forum to brag about there children if you can't see how sad that is I feel sorry for you.

Pretty much.  The final step that removed it from the discussion in my system were the CAD Ground Control units.  Apparently, high frequency noise is the enemy when it comes to digital.  Not cheap, but couldn't imagine my system without them.
