DID CABLE CAN ACTUALLY IMPROVE SOUND??
I can’t answer this question. What I can say is this: there lot of bad cable, wich mean, they are wrongly construct and have impendance-resistance issue. So these cable can decrease sound quality and clarity, either by pushing some frequencies to hard or the opposite or creating background hissing.
A good well made cable should have big ZERO resistance, so no distortion is cause by conductivity issue. We can find those for very cheap…but in fact, its always blind buy and even our ears can’t tell the difference if it’s under 0.5ohm impendance…anyway, now I want to test ALL my cable. I suggest you doing the same because it look very very simple!!
PIEZO ELECTRIC DRIVERS ARE COMING BACK!
Lately we see appearing the use of piezo electric drivers into budget earphones, especially chi-fi one. Tough they aren’t use as single driver for the iem, this old but trustable technology open new doors for sound tuning, but the thing with piezois exactly the difficulty of well tuning them as they cannot produce low frequencies, and stop at 1khz, but what they can be phenomenal too is to produce extended high frequencies, wich can go up to 100khz! Hourray fro the audiophile bats! Anyway, if there right now a piezo hybrid IEM that is hyped its surely the SENFER DT6. At 25$, these can be a big revolution in sound value. Can’t wait to test them! As well, they perhaps inspire other brand to take the plung with this technology as we can see withe the NiceHCK N3 of TOTL chifi LZ-A6 that use a crazy configuration of 1DD for bass, 1x 7layer piezo ceramic for extended highs, 2BA for mid range and 2BA for treble!!!
There some simple info about piezo speaker:
”How Piezoelectric Speakers Move
The piezoelectric effect can be employed in the construction of thin-form-factor speakers that are valuable alternatives to traditional electrodynamic speakers in space-constrained applications. These devices are referred to as both piezo speakers and ceramic speakers.
Apply an electric field to a piezoelectric material and it will change size. The piezoelectric material will shrink or grow as charges are introduced or removed, but the base material will not.
This causes elastic deformation of the material toward or away from a direction that is perpendicular to the surface of the speaker. As soon as the electric field is removed from the piezoelectric material, it will return to its original shape.
As the speaker flexes and strikes air molecules, it causes a chain reaction of collisions that eventually reaches your ear. If enough air molecules strike your ear, the nerve cells send a signal to your brain that you interpret as sound.”
ABOUT SOUND PERCEPTION: A FINAL AUDIO LECTURE MUST READ
Human sound perception is a very fascinating process passing trough lot of different step before being properly (or badly) heard by us incurable music lover.It do not only is about mecanical and technical aspect, as human are singular creature with different physiology and psychology that will inflict on sound perception and interpretation. In a complex symphony work where multiple instrument play togheter, immediate memory will play a big part depending of difficulty for brain interpretation.Bach ”Art of fugue” contrapunctus is a good example of short-term memory challenge of sound perception, because we can either listen to whole melodies pattern mixing togheter or try to separate them and listen separately with brain struggling.
