This focus reflects ATR Service broader mission: to support and promote analog sound reproduction quality, preserving it for future generations of musicians, engineers, and listeners.

Experience True Analog Sound
Andrey’s commitment to analog sound also finds expression in his high‑end listening room in Seattle, designed as a reference environment to showcase the very best in reel‑to‑reel and vinyl playback.
Here, visitors can experience music in its purest form — the natural timbre of instruments, the “air” of the recording space, and the effortless musical flow that only continuous analog sound can deliver. Many mastering engineers, musicians, and seasoned audiophiles who have visited have expressed amazement, often saying they had never before heard reproduced music with such realism and emotional impact.
While digital formats can be excellent, hearing analog at its highest quality is an unforgettable experience — one that can change how you think about recorded music forever.
Andrey warmly invites audio professionals, sound engineers, and fellow audiophiles to visit and share in this passion for preserving and celebrating the art of analog sound reproduction.
