Thank you for choosing our products!
With the development of the OBELISK separates, our aim was to take our highly praised
and award-winning Obelisk Si integrated amplifier to the next level of performance, in terms
of both functionality and sound. Using separate components for the various amplifier stages
gives more flexibility of use and achieves more transparency, information retrieval and
dynamic capability. We sincerely hope that you will agree, and that your Obelisk separates
will provide you with many years of impeccable, trouble-free operation.
Happy listening!
These components are designed to offer the finest performance available by avoiding
compromise, wherever possible. This detailed guide contains advice specifically related
to using this amplifier combination, as well as more general warnings about the use of
domestic audio components.
