innuOS Operating System

Powered by innuOS

innuOS allows complete Music Library management using a tablet or smartphone. Ripping CDs, importing music, editing album data (including covers) and backing up your music library can all be done easily without the need for a PC/Mac computer. innuOS also contains many intelligent features to help organise your Music Library such as our rule-based music import engine or the Assisted CD Ripping mode.

INTELLIGENT CD RIPPING

Bit-Perfect Ripping

Using AccurateStream technology, extract every last bit of your CDs into WAV or FLAC files.

Automatic CD Ripping

Just pop-in a CD! innuOS will automatically get full album data and cover from multiple online databases, rip your CD and eject when done.

Assisted CD Ripping

Assisted CD Ripping allows you to see and edit all the album data and cover obtained from the online databases before you rip the CD. Great for Classical Music!

Quiet Mode

Love to listen to music whilst ripping your CDs and want absolute silence? Just engage Quiet Mode for slowing down ripping, making it much quieter and with less vibration.

Offline Ripping

CDs can be ripped without internet connection. When connected, album data and cover for all offline ripped CDs will be obtained with a simple click.

DIGITAL MUSIC IMPORT

Import Wizards for Existing Libraries

Pre-defined wizards for importing music from USB storage, Music Servers and NAS.

Intelligent Import Engine

innuOS takes all the hard work of importing music by intelligently analysing the music files and applying a number of rules such as:

• Organising the music based on format quality (compressed, cd quality or high-resolution), Artist and Album
• Removing very long file names or illegal characters
• Adding metadata to WAV files based on folder structure

Download from Online Stores

Qobuz, Linn Records, HD Tracks, HiResAudio, B&W Society of Sound, iTunes, Amazon and more. Just download the music files (even if they are in a zip or tar file) to the Auto Import shared folder and the server will take care of adding and updating the music library.

MUSIC LIBRARY MANAGEMENT

Edit or Delete Albums

Browse your library, select the album you want to update and just start editing directly on your tablet or smartphone. You can change the cover, manage genres based on previously used genres or simply delete the album – couldn’t be easier.

Quarantine

Quarantine is a staging area, separate from the Music Library, where any albums requiring attention are placed so they can be fixed before they go into the Music Library. These include:

• Albums with no metadata
• Ripped albums with damaged tracks
• Potentially duplicated albums
• Albums ripped offline

Automatic Music Library Update

After music is added, modified or deleted, the library is automatically updated as well as any connected systems such as Sonos or UPnP Streamers.

MUSIC SERVER MANAGEMENT

Automatic Network Identification

No more figuring out IP addresses find your server. Just go to my.innuos.com on your tablet or smartphone to list all Innuos devices on the network and access the innuOS App from there.

Remote Updates

Update the system with a touch of a button to benefit from our continuous improvements: new functionalities, enriched customer experience or enhanced sound quality.

Automatic Backup to USB Drive or NAS

Backup of your music library can be set on innuOS to start automatically based on library growth (e.g. every time 50 CDs are added) to either a USB backup drive or to a NAS on the network.

It’s testament to Cristian Anelli’s customer support ethos that the now middle model in their converter line benefited so rapidly from the R&D behind the flagship Formula and its FPGA-controlled discrete resistor ladders. It’s a very concrete benefit of Aqua’s modular approach. Existing owners get to enjoy the company’s IP advances without the usual sell/buy routine. Keep what you already have; bolt on real not cosmetic go-faster mods as they release. Anti obsolescence protects your valuable hifi investment with more current tech. Especially with fast-moving digital, the Joneses relocate a lot. Keeping up with them requires eyes glued on the ball. Aqua’s policy doesn’t drop it. That deserves applause. An already widely accoladed converter just became even better. It’s a most excellent place to invest your next upgrade grand into!

“Back in March 2014, Aqua Hifi’s visually unassuming La Scala MKII D/A converter not only took out a DAR-KO Award but landed pole position on the Darko DAC Index, beating out contenders from AURALiC, Resonessence Labs and PS Audio….

In other words, the most satisfying DAC heard by yours truly to date just got significantly better. Modularity coupled to a manufacturer upgrade programme brings owners of existing La Scala MKII in from the cold (should they wish to).

In its Optologic incarnation, the La Scala MKII cements further its position at the very top of the DAR-KO DAC Index and DAR-KO Award assignation becomes as easy as it has ever been. In a word, primo!”

“While I’m not quite ready to sell my analogue gear, La Scala MkII is a fantastic product whose warm sonic embrace I can’t imagine anyone in their right mind describing as “digital”. It does have a sound though: It’s wonderfully musical, inviting, enveloping, and entrancing.”

“Yes, LaScala slightly boosts intonation, yes, it feels it, it’s his own enthusiasm, but if you want that very not-conveyed “attracter”, then this is one of the most vivid examples of such an approach in the High End. Practically exemplary implementation of the music, in combination with the overall high class of reproduction. My best recommendation.” (translated)

Formula xHD DAC

Introducing our proprietary Optologic D/A conversion system

Introducing the new Formula xHD

---

The Optologic R2R conversion system

aqua believes that the more musical D/A conversion system is based on the circuit usually identified as “resistor ladder”.
This technology has been substituted in the mass-market by the so-called sigma-delta converters.
The sigma-delta converter is a near-completely digital circuit and for this reason it can be can be integrated on silicon and produced at low-cost.
A quality resistor ladder DAC instead uses a circuit based on a set of high precision discrete resistors: at least 2 resistor banks, one for each stereo channel.
The Formula DAC is the first in the aqua’s production to show a proprietary D/A conversion system, that we name Optologic.
The signals sent to the resistor ladders are generated by a proprietary digital circuit, implemented inside an FPGA (Field Programmable Gate Array).
Formula has a sign-magnitude converter structure, and this requires not two but four 24 bit resistors banks, each one made of very low tolerance discrete resistors.
In order to separate the digital section from the sensitive analog circuits,  galvanic and magnetic isolations are implemented between the FPGA and the four branches of the R2R ladder converter.
This creates complete isolation of all digital circuitry – including the clock – from the analogue section, for a clean, noiseless ground plane. It also plays the main role in the differential management of the R2R ladders, achieving perfect symmetry between the counter-phase halves. The result is the highest tonal contrast and naturalness.Pure 1x native sample rate DAC

The Formula, like the other aqua models, is a digital filter-less DAC.
Our conviction is that in spite of the instrumental measurements showed by upsampling / oversampling DACs, they rarely are able to produce the same emotional and realistic results.

Modularity

A third important aspect in the aqua production is the modularity of the various electronic circuits.
aqua equipment are not short life products: as modular, they are open to future improvements and to follow the evolution of the technology.
Formula is made of a set of circuits every one developed on a separate printed circuit board easily interchangeable.
As an example, each of the four resistors banks of the converter is separate and mounted on connectors.

State of the art digital and analog electronics

As explained before, the Formula DAC uses no digital filter or any other compensation, relying instead on maniacal attention to each sub-circuit.
The separate analog and digital power supplies are executed purely by extensive use of discrete BJT, Mosfet, J-Fet and ultra-fast diodes.
Passive parts were selected not just for the best sonic result but also for their top quality, longevity and reliability. With the exception of six superior electrolytic capacitors, all other caps are Tantalum, solid-polymer OS-CON and double-metalized MKP.
The signal path itself is direct-coupled and completely capacitor-free.
The two output stages (one single-ended, one transformer-coupled balanced) use discrete BJT and J-Fet with metal-film resistors. All the electronics parts show an ultra-low RF noise.
An advanced ARM microcontroller manages the user interface on the front panel, the IR remote command and the communication port (serial, RS232 standard).

The xHD update

This update has required significant optimization of code for the main FPGA of R2R ladder DAC which has improved sound quality.
