About Ciúnas Audio
Ciúnas Audio arose from the conviction that low level noise which fluctuates with signal processing, is one of the most overlooked issues in audio playback systems, having widespread detrimental effects in dynamics, speed, inner detail, resolution, transparency, tonality, imaging, soundstage - all summed up in one word musicality.
Pristine, low noise & stable power was premised as one of the ways to investigate this issue.
In 2009, I became aware of a relatively new battery technology which which had been developed for powering electric vehicles. These batteries being 3.3V nominal output, could be used to directly power many digital chips & proved to be one of the best power sources I had heard. Yes, they improved sound when used as the power source into voltage regulators but far better when fed directly to devices. I now always use DIRECT power from batteries (& now supercapacitors) to power audio devices which results in a very noticeable improvement in sound, even compared to using some of the best regulators (currently LT3045)
Voltage regulators use feedback to maintain their regulation & measurements show that even the well regarded LT3042, suffer noise issues under dynamically changing loads (not the fixed loads used for datasheet measurements). Batteries & supercapacitors having the qualities of impressive stability due to very low impedance & huge instantaneous current delivery, speed & ultra low noise levels, act like a flywheel where dynamically changing loads have zero effect.
These characteristics are perfect for powering all devices in the digital audio chain as it avoids one of the main sources of electrical, low level noise in audio playback. This is not a hum or buzz heard through the speakers - read the effects of noise on our perception of music playback here. This makes a profoundly audible perceived difference in any area I have used them on audio devices.
I have now moved away from battery as a power source as supercapacitor power sounds more incisive & faster.
The result of this research, experiments & testing was
Ciúnas Audio (Ciúnas is Gaelic for calm, stillness, serenity)
