Thank You.
All of us at Burson Audio would like to say thank you, and congratulations for purchasing the Burson
Soloist 3XP. We sincerely believe that your Burson Soloist 3XPP is an intelligent investment that will
bring you many years of musical enjoyment and satisfaction.
We understand how eager you are to begin listening and we want you to become familiar with the full
capabilities of the Burson Soloist 3XP. However, before powering on the device, we encourage you to
look through the manual.
Team Burson 
The less the equipment tampers with the music, the greater the music becomes. This has been the
core design philosophy of Burson Audio since 1996. If the equipment is honest and transparent then
the proper tempo, dynamics and tone will materialize as a natural expression of the music and it
becomes unnecessary to flavor the original sound. We believe that this ideal can never be achieved
through standard circuitry building blocks such as opamps, IC regulators or even standard
transformers. Instead we work towards this ideal through the research and development of
customized solid-state circuitries that are developed specifically to suit our applications. Only then
will each and every component involved be pushed to their performance peak. And only then will the
end result be consistent with our idealism.

XLR to RCA Output:
To achieve an ideal sonic performance, the XLR outputs of the Soloist 3XP are direct coupling. ie. It
has no coupling capacitors or transformers on the audio signal path.
However, direct coupling outputs are not compatible with off-the-shelf XLR to RCA adaptors like the
ones showing below. Using such adaptors to connect the C3X to any single-ended amplifier with RCA
inputs will damage the internal opamps of the C3XP.
Therefore, to safely connect the Soloist 3XP to any single-ended amplifiers, please use the
transformer type of adapters below.
Unpacking
After carefully unpacking your Burson Soloist 3XP, inspect for any shipping damage and call your
dealer immediately if any is found. Do not plug your Burson Soloist 3XP into any outlet if you find
shipping damage. Please save all packing materials so the unit can be easily and safely shipped if the
need arises.

Break-in, Warm-up and Caring
The sound of the Burson Soloist 3XP improves steadily within minutes after powered-up. Depending
on the resolution of the system and the attentiveness of the listener, you may find that the sound
continues to improve over the first several weeks of operation.
Never, connect or disconnect the headphone jack or the RCA cables from the Soloist 3XP while music
is playing. This could damage the Soloist 3XP. After your listening session, please disconnect the
headphone jack from the Soloist 3XP to prolong the working life of its headphone output socket.
