Why use a Audio Buffer? Impedance mismatching... your audio system probably has it. What is it?
Impedance mismatching refers to a situation where the various audio gears are not fully synergised (meaning there is a impedance and gain
mismatch, which lowers resolution and dynamics significantly.). This usually occurs between the source (CD player, Dac, Ipod) and the rest of the
audio setup. If your various audio equipment, cables, speakers, listening room are not working with each other then you cannot expect to hear the
full potential of your system. Therefore, careful matching of audio components is critical in performance optimization of any audio system.
When audiophiles listen to their newly purchased component at home, they often find the sound quality doesn’t match up to what they heard in
the shops demo room. The sonic characteristics that persuaded them into purchasing the machine in the first place have simply 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 shop”. The
end result is often more upgrades and further misinformed or ill-advised investments.
Many audiophiles are not aware that the performance gap between what they hear in the shop and what they hear at home is a direct result of
impedance mismatching between the new machine and the rest of their system. Impedance matching is a complex technical issue in audio design.
What makes it worse, is that the same manufacturer can have different output / input (I/O) impedance standards across their range of products.
Mismatching in Hi End Audio
Different circuitry designs produce different input and output impedance. Therefore, impedance compatibility needs to be considered before
buying any piece of audio equipment. However, while some manufacturers are willing to disclose the I/O impedance figures, others are not.
Therefore unless the entire audio system is purchased from the same manufacturer within the same product line, it is most likely that impedance
mismatching will exist. As a result, the audio market is full of confusion, myth and plenty of ill-advised investments. Due to impedance mismatching,
it is very likely that most audiophiles are only hearing approximately 70% of their systems full potential.
Mismatching in IPod & PC Audio (the file format may be lossless but is the playback lossless?)
Ipods and PCs can play back lossless audio files that are identical to CD quality. But when connected to a high-end system, they always sound flat
and lifeless compared to even a cheap $200 CD player! There always seems to be a need to turn up the volume to achieve a similar level of
sound. . Why?
The reason is that the Ipod and soundcards were designed to be compact, light weight and energy efficient. Their audio output stages are
completely different to any home based audio equipment. The Ipod is powered by a 5V battery and the soundcard runs on 12V, while, a home
audio equipment will always run on 24V+. Therefore Ipods and soundcards were never designed to synergise with any of the hi-end amplifiers, so
one can only imagine the amount of impedance mismatch between them. Therefore, although that audio file is lossless, the play-back through an
amplifier is certainly not!
The Burson Audio Buffer is designed to remove any impedance mismatch by acting as an isolation platform between any of the source components
e.g.(CD, DVD, SACD player, Phono preamp, PC sound card or even an IPod) and downstream amplification (preamp, intergraded amp, etc). The
Burson Audio Buffer will increase signal transmission efficiency between all components, unlocking the potential of any system.
