yes. static charges added onto discs do sound plausible.

however, i donâ€™t believe transparent cases are removing static â€“ they are probably still adding static, but of a different type instead.

here's a test you can try easily (for a healthy system unlike mine):

wrap your CD in common kitchen aluminium foil. there are usually 2 sides to aluminum foil - 1 shinny side and 1 matt (non glossy) side. take turn to wrap each side over the same CD and play it. the shinny side will create a bright thinny sound, while the matt side will create a very dull sound. both sides are adding static. but the static condition they created onto the disc is opposite to one and the other.

so if we assume the black colour case is adding some static charge, while it cause my system's imaging to skew towards the left (always the left), it also impart a mellow, bloated sonic signature to the sound as well. i notice, over some time, some of this sonc signature get attenuated the longer the disc is being played.

when the same disc has touched a transparent case, and then played through my system, not only does it kick centre-fill imaging back to centre position again, it also imparts another sonic signature - something brighter, a more open and recessed soundstage. some low level details like piano pedals and intake of breath become more audible. but this change is not "stable". overtime, the sonic signature and the size of the soundstage get attenuated, the longer the disc is being played. but all the while the center-fill imaging remains stable in the center.

if the dark grey cases are adding static, then it stands to reason that the transparent cases are adding static too - albiet of the opposite type. So when this opposite-static-charged disc is played in my system, it restores equilibrium to my system previously infected with static in the other direction.

now i believe when the audio system has a neutral static condition â€“ a balance containing either types â€“ then imaging can be properly projected.

makes sense?

now take this further - if an audio system is not afflicted by any adversed static condition - then sound can be further improved?

this will be a subject of future posts.
