About the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
First, we don’t just use advanced technologies like ultra-high-speed digital hardware, precision audio clocking, or noise filtering—we develop them ourselves with a deep understanding of how each element affects sound quality. For example, our proprietary power electronics for audio circuits and custom-designed oscillators play a critical role in delivering our distinctive sound.
Second, while many brands prioritize marketing, we invest heavily in R&D. This means our products may not always be the most widely advertised, but they are built on a solid foundation of innovation and long-term vision. Rather than making minor upgrades, we aim to create fundamentally better products with each release. That’s a philosophy that consistently earns us loyal users around the world.
What's your approach to customer support?
At SOtM, we take customer support seriously. Customers are encouraged to first contact their local dealer or distributor, as they are trained to handle most issues and can provide service in the customer’s native language. However, if further assistance is needed, customers are always welcome to reach out to us directly. When a customer experiences an issue, we aim to respond quickly, diagnose the problem accurately, and offer a solution that minimizes any disruption. We go above and beyond by offering firmware updates, personalized setup help, and sometimes even remote access support to ensure the best possible experience.
What are your favorite tracks for showcasing the strength of your products?
Some of our go-to pieces include:
- Stravinsky – The Firebird Suite (Finale): Great for dynamics and layering.
- Copland – Fanfare for the Common Man: Perfect for testing impact, timing, and space.
- Mahler – Symphony No. 2 "Resurrection": A true challenge for any system, with massive scale and emotional intensity.
We also enjoy film scores for their emotional engagement and wide frequency content. Ultimately, we choose tracks that are musically moving and technically revealing—regardless of genre.
What other products pair best with yours?
Since we produce everything from digital sources to amplifiers and cables—essentially all components except speakers—we typically use speakers from brands like Focal and Magico in our reference systems. All other components in the system are SOtM products, allowing us to demonstrate the full potential of our technology in a fully optimized environment.

What are two key technological innovations or strong opinions that differ you from other brands?
Industry leading intuitive touch panel interface and 4K video support, which allows you consume content in a new and immersive way without sacrificing audio quality.
What's your approach to customer support?
We have a dedicated service and tech support team. Our sales reps are also trained on supporting the line.
We always encourage the dealer to be involved in the support process since many of the issues can be resolved at the dealer level. Having the dealer involved also provides an opportunity for them to learn how to resolve more common issues. We are also happy and available to assist end users who reach out to us directly.
The best course of action is to reach out to your dealer and alert them of an issue. If your dealer is unable to resolve the issue, they can reach out to their rep or our support team for assistance. If they do not have a dealer, our support team is available via email at [email protected]
Monday through Friday from 9am to 5pm CST.
Our goal is to respond to support issues within 1 business day. If a product is deemed to be defective within the first 30 days of receiving the unit, we will usually offer to replace it.
