I've been dealing with "Digital Glare" since 1985 and tried Green Markers, Disc Mats, Armor All you name it. I have owned more Disc players and DAC than I can or want to remember. The following is what's worked the best for Me: Ripping all my Disc to a computer and using iTunes and it's digital Equalizer, then into a DAC. 2nd and near as good as the eq is my Esoteric DV-50 with it's up sampling and filter features. That said, some folks get there shorts knotted just thinking about Eq's, I used too but a wise old Man told me, It's your music listen to it any darn way you want, you paid for it.
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.
