While we know that impedance mismatching is a big problem in audio systems, it seems that this problem gets overlooked often. The Audio Buffer 160 attempts to fix this problem, and it is designed to match the output impedance of your source (CDPs and DACs) to your amplifier
As quoted from Burson 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.
They also posted a table with some output impedance specifications of different sources, which seems to demonstrate the real importance of an impedance matching device.
Arcam CD192: 47 ohms
Arcam CD73: 150 ohms
Arcam CD36: 50 ohms
Mark Levinson N3905: 15 ohms
NAD C542: 150 ohms
NAD C521 Beee: 300 ohms
So, the argument is valid. Anybody interested in giving it a try, or should we do a review on it?

hi guys. are you planning to give us a review for this beautiful thing?
hey i would very much like to see a review on the buffer!
great site, keep it up
The Burson Buffer. Ah, sorry no plans for it yet.
But I am writing a review on the HA-160 amplifier. It’s quickly becoming my new favorite amplifier.
