Arca is a sound that is transparent and has excellent linearity, a somewhat common concept, but it has been realized through Virtues' interpretation and originality . Although the concept appears transparent, the reality is different. Arca maintains resolution, transparency, and audible naturalness while offering attractive velocity, clear separation, and a rich, high-quality mid-range. It produces a sound image that is never hard, but rather soft and transparent, with a gain range from clean to classical distortion. Visually speaking, it gives the impression of a landscape seen through a lens, and this sound image is what we define as translucent.
