Based in Bovey Tracey, Devon, Stack Audio is an audio company that designs, develops and manufactures its products here in the UK.
FOCUSED ON THE SOURCE
From the outset, a focus on the source has been the foundation for everything Stack Audio does.
In pure audio terms, focus on the source is about producing the purest musical signal free from interference at the start of replay. DACs, phono stages, amplifiers, speakers and headphones all sound better fed with a clean signal. Focusing on the source removes the need for excessive filtering ensuring no noise cascades down the system. It also means ensuring acoustic energy is not fed back into the system and electrical circuits, so that you hear the music signal just as the producers intended.
Concentrating on source equipment means we stay focused one of the essential elements of hi-fi music replay. We believe high-end hi-fi doesn’t have to come with high prices. Stack Audio products are designed to work well in all systems.
2013-17: Digital - ONSET
The ONSET was an early high-end network streamer designed to work with external DACs. Ahead of its time, the ONSET laid the foundation for ‘Focus on the Source’, with an uncompromising approach to producing a simple, clean digital signal. The ONSET utilised a high-quality linear power supply, kept separate from the sensitive digital circuits. This has had a profound influence on subsequent Stack Audio products.
2021: Refinement - LINK II
2021: Power - VOLT
Everything starts with power. Having designed an external linear power supply for the LINK, Stack Audio is expanding the range to offer linear power supplies for other source components. The VOLT’s internal design is by Phil Balaam of Nytech Audio who has worked closely with Stack Audio and utilises high quality audio grade components all housed in an aluminium case.
