Στην Resonessence Labs έχουμε αναφερθεί στο παρελθόν στο forum, για κάποιο λόγο με ιντριγκάρει σαν εταιρία, οπότε θα σας παρουσιάσω με λίγα λόγια το Invicta Mirus Dac της.
Ο κυρ ιδιοκτήτης της (Mark Mallinson), ήταν και ο Operations Director τηε ESS Technology, οπότε μοιραία ο κύριος χρησιμοποιεί τα εν λόγω τσιπίδια με απότερο σκοπό του να απομυζάξει ότι καλύτερο έχουν να δώσουν.
Official Site
Our top-of-the-line product an outstanding DAC for the ultimate in performance. MIRUS uses a dedicated SABRE 32 (ESS9018) per channel: eight DACs in parallel to each stereo channel. USB Audio 2.0/1.0, DSD over USB, SPDIF and the unique SDCard reader are provided. The SDCard supports WAV, AIFF, FLAC and DSD files.
Mirus supports input data rates up to 384kS/s and features advanced Resonessence filters.
Specs
Input
Asynchronous USB 2.0, SD/SDHC/SDXC cards.
The USB supports up to 24 bit/ 384kHz as well as DSD64 and DSD128.
The Card supports 24-bit / 384kHz for WAV and AIFF, FLAC is 24/192k. AES/EBU (S/PDIF) and 2 BNC (S/PDIF) inputs are included that support up to 24/192 kHz.
A Toslink (S/PDIF) is also included.
Output
(1) Pair Unbalanced (RCA) and 1 pair XLR.
An HDMI Output is included for reading the directory structure of any of the card formats with an HDMI connected monitor.
A Toslink output for the SD card data.
Dimensions
8.66" wide by 11.10" deep, by 1.97" high
Weight
6.4 pounds
Features
- Dual ESS Sabre ES9018 DACs per channel
- USB interface code is Resonessence Lab’s own. The Windows drivers are provided by Thesycon.
- A digital volume control with the necessary range to successfully drive amps directly.
- Analog Devices AD/797 op amps in the analog circuits. While the use of this op amp is somewhat controversial for a high end DAC, Resonessence Labs has found that this op-amp is a high linearity open loop design that has the benefit of matched, complementary, on chip, bipolar devices. Resonessence Labs selected this design as it yielded the best sound for their DACs. A detailed explanation of this design can be found at the FAQ at their website.
- Galvanic isolation of ground noise using multiple power supplies as well as separate grounds with a separate power supply for the digital section. With galvanic isolation, the audio system ground is not disturbed by the USB flow control artifact. Phase noise modulation with power supply variation is also kept to a minimum.
- Resonessence utilizes the jitter rejection aspect of the Sabre DAC (activating its Asynchronous Sample Rate Convertor and Jitter Removal Circuits). This results in a further up-sampling to the precision master clock rate, which in all Resonessence products is an ultra-low jitter fixed-frequency 50Mhz CCHD-950 clock.
- DSD over PCM (DoP) for playback of dsf and dff files via USB and S/PDIF
- 7 selectable filters that can be changed while music is playing. 2 of the filters are the pre-programmed filters found in the ESS Sabre DAC. The other 5 were designed based on user feedback.
- An Apple remote is included with the Mirus.
- An elaborate front panel display that allows various user configuration settings and display of volume settings. An LED display is also provided to indicate sample rate and DSD playback.
