Invicta / Mirus
A Canadian company specializing in world-class digital and analog converters at several price points, Resonessence Labs offers units designed and assembled entirely in house. Resonessence's unique knowledge of product design and implementation comes straight from the founder, who gained experience as director at ESS Technology, the company responsible for the celebrated Sabre chip.
You can count on the INVICTA to provide the three essential parts you expect of all complex machines of today: the hardware, the upgrade-able firmware, and the operational software. Here you find Resonessence expertise in an audio DAC.
Resonessence worked through many prototypes before finally choosing INVICTA, the hardware that implements all firmware and software the company offers, including those that have yet to be released. Resonessence has taken into consideration what Apple, Microsoft, Open Source teams, and others will create, what the market wants, and what the industry insiders determine to be the future of INVICTA to create a hardware base on which these features will run. For example, users have the ability to choose seven filter types, a feature that was not a part of the original design.
The INVICTA provides users with the ability to program every aspect to some extent. For example, the IO ports meet or exceed the physical layer specifications, so that for example, the three rear BNC connectors are electrically isolated, capable of 75 ohm impedance match, two are programmable as input or output, and currently configured as two selectable SPDIF inputs. These features are available because reviewers wanted it. If customers prefer elements such as Clock and Data, Word Sync, etc., then an easy software upgrade can create that. Furthermore the HDMI interface allows users to display files stored on the SD card, and in future it will be possible to implement I2S over HDMI, HD OSD output, even ultimately HDMI Audio input if technology moves in this direction.
Even though the INVICTA is a complex, highly reconfigurable product that may please your intellect, remember that this is secondary: it is first a machine to move you emotionally with superb sound.
Dynamic ESS Sabre DAC Implementation
Invicta is designed, manufactured and assembled in Canada. At a very early stage they recognized that to succeed they needed to outperform the competition in a number of key areas, one of which should be build quality. Their attention to detail is perhaps best summarized by the chassis designers, IMWorks of Kelowna B.C.
“It is very rare that we are approached by an organization that wants to truly place quality in front of cost. There are many that say quality is foremost, but in practice this is very rarely the case. Resonessence Labs has not restricted our design/build process in any manner. We have managed to complete what we consider to be the perfect chassis for this product.”
Working very closely with IMWorks Resonessence have spent hundreds of hours perfecting the design of the chassis. The materials, finishes and construction technique are all done to precise specifications.
The practices chosen for assembly of the chassis are not typical to the conventional electronic enclosure industry. The front panel is a structurally integrated part of the chassis assembly, not a cover to hide a stamped steel sub-chassis.
After several computer guided procedures, the bottom plate is ready for anodizing and assembly.
Many of the tolerances on the manufacturing drawings are held within .001”. The main front panel and chassis base are machined from solid 6061 T6 aluminum. The internal sheet metal components and fasteners are all manufactured from stainless steel. The latest high speed CNC (Computer Numeric Control) machining and CAM (Computer Aided Machining) technology is employed to help complete this process. The precision and repeatability of this equipment results in parts that are exactly the same size ensuring a precise fitment during the assembly process. Laser etching is employed for the permanent marking of the front and rear panels. The front panel sub-assembly is extremely complicated, containing no-less than 27 fasteners. The result of this design is a front panel UI (User Interface) that feels as if it were carved from a block of granite. The solidness of the switching is profound in its conveyance of tactile feedback. The overall robustness and heavy weight of the chassis design can be felt in your fingertip each and every time a button or knob is operated.
Each unit is hand assembled and then individually tested at the Resonessence engineering facility in Kelowna B.C. The units are then run continuously for 100 hours prior to shipping. No further burn in is required following shipment.
