Top 5 High End Audio Cable Jargon Terms Explained
Modern day cable technology for audio has not had significant advances for many years. 1) SCC OFC, UPOCC, SGC, SGSCC, etc.
The idea is that your standard copper cables contain many crystals per length of wire. This is because all metals form crystals during manufacture, and if under non-ideal conditions, will form many crystals in the ingot. When drawn out into a strand of wire, the crystals form distinct sections of cable, which is theorised to act as small resistors with different electrical characteristics. 2) Smooth surface copper
The smoother surface of the wire translates to a purer conducting medium.
3) Teflon/cotton dielectric (insulation)
Again, this may be a good way of insulating cable on a small scale, but it is not practical for speaker cables or any high output signals.
4) Silver conductors
If Teflon is one of the less contentious technologies around, then silver is one with significant backing in industry. Excluding experimental materials which are impractical to use as cabling, silver is the best conductor that we know of. This argument has some foundation, as silver has incredible high frequency performance (hence their use in demanding applications). 5) Cryogenically treated materials
High End Home Cinema Acoustics - Bonello Criteria
In home cinema installations, the number of resonances within a given frequency bandwidth increases with frequency. If the number of modes per third octave band increases monotonically then there is a good chance that we will perceive the dedicated home cinema room as having a 'smooth' frequency response despite the resonances.
If the number of resonances found in a home cinema installation per third octave drops as the frequency rises, then there will be a perceptually noticeable peak in the frequency response.
