Adjust your system to improve it
Your audio system’s sound quality can be easily improved with a few adjustments.
1) Record player
Check and tighten screws (tonearm stand screw, all screws on the motor board).
Treat connectors’ mating surfaces with a cleaning & rejuvenating solvent (headshell terminal, tonearm output terminal).
Since speaker vibrations have a negative impact on amplifier sound, place devices as far apart from one another as possible.
Place carbon isolation under the amplifier to avoid the influence of speaker vibrations. This improves sound quality in the lower register and makes the full bandwidth sound clearer.
Connect a film capacitor wider than 1-2,2 μ parallel to the amplifier’s electrolytic capacitor. This lowers power supply impedance in the upper register, decreases distortion and improves sound width and depth.
Ground the frame of the speaker unit and the metal part/core of the crossover network. Muffled, blurry sounds become crisp and clear, S/N ratio improves, wooly basses tighten, and speakers attain excellent silence reproduction.
For the crossover network, use film capacitors, but not ones with high capacitance. For the most part, film capacitors do not change sound texture much and do not cause coloration. Conversely, oil-filled capacitors change tone color and quality, creating sound that lacks the right width, depth and distinct reverberation.
If the crossover network coil has as an air core, coils should be kept apart by at least 50 cm or more, as significant magnetic flux cause interferences between coils, and sound quality deteriorates.
If a mounting clasp/band is present, it should be made of non-magnetic material, and there should be a space between the coil and core affixing point. Without that space, coil inductance changes with frequency, and crossover response becomes unstable.
Coil made of flat copper wire has large stray capacitance, which produces surges in impedance and in turn creates peaks and dips of sound that disrupt sound balance.
As with amplifiers, crossover networks can be affected by external vibrations, so to prevent distortion, it is advisable to use carbon isolation or maintain a proper distance from the speakers.
Because vibrations emanating from speaker enclosures can reverberate throughout surrounding structures like the floor and walls, we find ourselves listening not only to music, but to the sounds of those vibrating elements as well. Place a carbon de-coupler/isolation underneath your speaker system for astonishing tone quality improvement. Using a carbon de-coupler/isolation also significantly improves howling margin, and creates clearer musical scale as well as accurate tone of musical instruments. The resulting improvement on sound quality is beyond imagination.
In a multi-way speaker system, it is vital that the sound image positions reproduced by each unit harmoniously blend. If they do not, not only does sound become fractured and unnatural, but it becomes impossible to level sound pressure.
Conversely, if sound image positions successfully blend, you do not feel the presence of the speakers, and the sound becomes strikingly natural.
