From Burson
Burson Audio is challenging the conventional and pushing the boundaries of audio excellence through innovation.
An old school DAC / Pre Amp
We don’t use DSP to over-sample or reprocess the original digital signal. And we didn’t put a tube output in parallel to a solid-state output to sweeten the analogue signal and attract eyeballs. Instead, the Composer 3X Performance plays truthfully, from MP3s to native DSD512, without bass boosting or sugar coating.
With a powerful SABRE32/ESS9038Q2M DAC chip, a minimal signal path and a mighty power supply, the Composer follow an old school design approach, and it recreates the original art with pinpoint accuracy.
A Timeless Classic
But hang on! Don’t a lot of high-end DACs use ESS9038 and Xmos, and lots of DACs claim to use high-end parts. Without a glowing tube output, a porthole to peek at it and a fancy DSP sales pitch, what makes the Composer unique!?
Every music composer works with the same set of notes. Those with the right focus and experience create timeless classics by arranging them in the right way. Those wanting to shock and collect “likes”, those using focus groups to put together designs instead of using their hearts usually create something forgettable. The Composer 3X Performance is excellent because we did the hard yards. It sounds incredible in the old school way, and we know it is a classic.
