Impedance Mismatched? It Has Happened To Us All
When audiophiles listen to their newly purchased components at home, they often find the sound quality doesn’t match up to what they heard in the store. The sonic characteristics that persuaded them into buying the machine in the first place have just vanished. This all too familiar situation, often leads to most audiophiles blaming the remainder of their system for “not being as good as the one in the store”. The end result is often more upgrades and further misinformed or ill-advised investments.
The Nuts And Bolts Of It:
|Brand / Model||Output impedance|
|Arcam CDS27||47 Ohm|
|Arcam CD73||150 Ohm|
|Arcam CD36||50 Ohm|
|Mark Levinson N390S||10 Ohm|
|NAD C542||150 Ohm|
|NAD C521 BEE||300 Ohm|
|Schiit MODI 2||75 Ohm|
Impedance matching is a complex technical issue in audio as different circuitry designs produce different input and output impedance. What makes it worse, is that the same manufacturer can have different output/input (I/O) impedance standards across their range of products due to design changes/updates. (See table below).
While some manufacturers are willing to disclose the I/O impedance figures, most are not too keen. In the 80s and 90s, most audiophile equipment accurately published them. Nowadays, impedance numbers have disappeared from most spec sheets. The result is an audio market full of confusion, myth, and plenty of frustration. Unless the entire audio system is from the same manufacturer within the same product line, it is most likely that impedance mismatching will exist. Most audiophiles are paying 100% for their systems but are only hearing 70% of its full potential.
The Cable+ Synergises any audio system:
The Burson Cable+ removes any impedance mismatching by acting as an isolation platform between any source components (CD, DVD, Media Player) and downstream amplification (preamp, integrated amp, active speakers). It is designed to Increase signal transmission efficiency and unlock the potential of any system.
