Is this DAC based on mktg or concrete stuff? Job
Dear all, I would appreciate your opinion about the JOB company DAC (they are a sister company of Goldmund)
Are their converter based on real quality or is just a well prepared marketing effort?
Don't say listen to them as they are not around in shops.
I herewith encluded some notes I grab in their web site.
MAYBE ANYONE OF YOU HAVE THE CAPABILITY TO READ BETWEEN THEIR ANNOUNCMENTS.
I am under debate about a Job DAC or just go for the nominated ART DIO Modded.
Please let me know.
Tks so much, hard question but sure you will help
Based on the latest Goldmund "Alize" ultra-transparent technology the JOB DA converter provides exceptional performance and a very easy access to the best digital source for a mini JOB system.
Its unique time alignment, ultra-low noise and distortion provide a transparency and accuracy to digital signals with all the soft and delineate characteristics of analogue.
Very reasonable in price for its professional quality, but also extremely small in dimensions for its performance, the JOB converter is a very versatile converter providing SPDIF coaxial, XLR balanced and Toslink connectors to receive any kind of source equipment.
The components used in this circuit are of extremely high quality, most are military grade. TECHNICAL
The principled used are not all in the public domain yet. However, it is known that the single high-density module used in the JOB DA includes 3 revolutionary circuits :
A new type of Digital Interface canceling all Jitter from the signal, based on a quartz locked frequency.
A new type of D/A circuitry, more accurate than any typical single-bit, multi-bit, 16, 18, 20, 22 or 24 bits D/A chip.
A new circuit of analogue filtering, multi-stage, extremely complex and providing the extraordinary time alignment of the unit.
The phenomenal time alignment of the unit is probably its main technical advantage. Providing a unique aliveness and exceptional "Recognition Factor".
