The Burson Audio Buffer AB-160 XLR

Impedance mismatching refers to a situation where the various audio components are not fully synergised.  This usually occurs between the source (CD player, Dac, Ipod) and the rest of the audio setup.  When the audio system is not fully synergised, it is not fully optimised, resulting in signal loss and distortion. 
The Burson Audio buffer removes any impedance mismatching by acting as an isolation platform between any source components (CD, DVD, SACD player, Phono preamp, radio, PC sound card or even IPod) and downstream amplification (preamp, intergraded amp,  etc). Burson Audio Buffer is designed to Increase signal transmission efficiency between all components and unlocks the potential of any 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. It is mainly concerned with the various types of output stage designs. 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 change / updates. (See table below).
mpedance mismatch frequently occurs in PC and Ipod based audio systems.  Due to their evident difference in operational  environments, IPOD or PC sound cards use different output stage designs compared to home based audio amplifiers.
 
That is why connecting an IPOD or PC sound card output to a Hi Fi system, will certainly result in impedance mismatch. The results are loss  of dynamics and texture. The more obvious symptoms include a lack of attack in the music (not just bass, but every single note played), a lifeless and thin “digital sound” and a need to turn up the volume to achieve the same sound level,
