Kassandra Signature DAC
R2R | DIGITAL TO ANALOGUE CONVERTER
The Kassandra Signature is our two chassis version in the Kassandra Series and completely redefines the status of digital replay.
We believe the Kassandra DAC is currently one of the best audio sources available today and can only be matched by top analogue sources in timbre and musicality, but keeping well ahead in aspects of dynamic presentation and resolution. While in the process of setting up and building the company, at the earliest stages, the need of a true SOTA source was mandatory. You cannot claim to build speakers that aim to be the absolute best, top amplifier designs and so on, if you do not have a true reference source. So the Kassandra was born…
