Our sources are fully fledged preamplifiers, therefore the volume control is a very important aspect. Most of the other products can only deliver a certain dynamic range of the signal only at their maximum output level, because they either have no volume control or they are using a digital volume, that has a very nasty side effect: as the output level decreases, the same happens to the dynamic range. We are using a pure analog volume control that is accurately managed by digital circuits. This way, the dynamic range is preserved regardless of the listening volume.The active elements adjusting the volume are either relays, that generate a typical sound while changing the level, or CMOS switches, totally silent. As we know, just a few exquisite preamplifiers feature this ultimate quality control circuitry and none of them is offering this redundancy.

This is a truly delicate matter. We use the best chip that actually exists, in such a way that we achieve the exact same performance as the reference development board supplied by the chip manufacturer, that was tested under ideal operating conditions: powered by chemical batteries, shielded completely inside a metallic enclosure connected to ground. In our design we have the possibility to change the ADC stage with an optional module that could host an alternative ADC chip.
The main design rule was: no compromise. The AMOLED display is protected by a very high quality optical crystal, treated with special anti-reflexion coating that has a violet tint resembling sapphire crystal. Apart from the aesthetics, much care was taken regarding shielding and cooling. Our design greatly improves the air flow, keeping the delicate electronics operating at optimum temperature during the many years of projected life.
We started from something that seems to be forgotten by many – the VU meters and spectrum analyzers. Let`s admit it, how many of us still hang on to our reel-to-reel or cassette deck, partially, because of the VU meters? We have blended all the high-tech mandatory for such a complete design performing so many functions into an interface that feels very simple and familiar. It contains all that you need, only when you need, nothing more and nothing less. Our control app runs on smartphones and tablets, a detailed pdf describing the functionality is available in the downloads section, along with Roon user guide . We include a fully working Roon, software and hardware, along with a complimentary licence.
We are providing a complete turnkey (plug and play) solution; borg.audio and Roon apps are complementing each other, the handover is seamless, controls and information being available to both of them.
Functionality covers, practically, everything.
You can listen to music files stored in any format or resolution; you can listen to any radio station; the DSP functionality allows the adjustment of various listening parameters according to your taste and it can also compensate for imperfections of any speakers and adapt them your home`s acoustic properties.
You can enjoy the best music on demand services, Qobuz and Tidal and benefit the maximum quality delivered by them; you can listen to any analog or digital source and you can record any of these.
Since, in real life, most of the times we are listening to a relatively low level, the quality of our volume control will be obvious. Very accurate VU meters or the spectrum analyzer are equally useful and pleasant to watch. For your comfort we have implemented voice commands.
Analog or digital sources can be accurately recorded. The system detects levels above maximum and adjusts the input volume very fast, this feature being very useful for preserving the dynamic range while recording any analog signal; at the same time, a music recognition engine finds the cover art and the artist, album and track name and automatically fills these details while saving the recorded file. If the information is not available, as no such system guarantees 100% success rate, the data can be edited later using the server`s user interface.
