Background information<\/strong><\/span><\/div>\n
The Myst\u00e8re IA11 is a hi-fi amplifier designed with the philosophy of delivering high-quality sound performance without compromise. Designers such as John van der Sluis have chosen robust materials like steel and aluminum for the chassis, which protect the internal components from interference. High-quality vacuum tubes are an essential component for the analog sound, adding amplification and warmth to the audio. The internal wiring is carefully hand-finished to ensure lossless signal transmission. Materials are sourced primarily from Europe to ensure consistency in quality. <\/span><\/div>\n
Brand history<\/strong><\/span><\/div>\n
Myst\u00e8re is a brand originating from the Netherlands-based company Durob. It was founded in response to a demand for tube amplifiers with a classic signature. The development of Myst\u00e8re was led by a team of experienced designers within Durob, with an emphasis on simplicity of use and operation without complex adjustments. Production takes place in a factory dedicated to Myst\u00e8re, with all final assembly and quality control performed by a permanent team. Introduced in the 2000s, the first models in the Myst\u00e8re line focus on ease of use and stability. The components in the devices are selected and tested by Durob. The designs are characterized by a symmetrical construction and a metal chassis with a black finish. The devices are designed to operate without external bias adjustments. <\/span><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
