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.

kosst_amojan" the data stream should be the same for any given CD every single time it's played regardless of the operating conditions"

What you are claiming here is the compact disk audio is always absolutely perfect everytime  but of course in the real world where most of us live outside of the trailer park that is not how things work and telling us "You don't seem to understand the nature of digital data on a CD" is not an argument in favor of your flawed assertion.

Just to clarify, by the time the digital data arrives at the DAC it’s too late. The data has already been corrupted. Reed and Solomon were just two older gentlemen they told to do the best they could with errors and their error codes do pretty well with scratches and fingerprints. But that about the extent of it. The damage occurs as soon as the laser touches the pits and lands. Within a picosecond or so. The CD laser and detector simply read and record STOP and START of pits and lands. It doesn’t become meaningful digital data until later downstream.
