Open Source Audiophile

Welcome to OpenSourceAudiophile.com, your go-to resource for exploring the world of high-fidelity audio through the lens of open-source technology. In the realm of audiophilia, achieving great sound often involves navigating many proprietary technologies and often punitive licensing fees. This site delves into the challenges and costs associated with licensing key audiophile technologies and explains why many companies opt for alternative solutions.

The High Cost of Licensing Audiophile Technologies

HDMI (High-Definition Multimedia Interface)

HDMI is a critical technology for transmitting high-quality audio and video signals between devices. However, integrating HDMI into audio equipment comes with substantial costs. Companies must pay licensing fees to the HDMI Forum, which can be prohibitively expensive for smaller audiophile manufacturers. Additionally, meeting the compliance standards and certification requirements adds further financial and technical burdens. These costs are often passed on to consumers, making HDMI-equipped audiophile gear more expensive. A good example of HDMI in an audiophile component can be found in the PS Audio DirectStream MKII DAC or the PS Audio Stellar Gold DAC which both use Philip’s I2S digital connection (no video) via HDMI. The NAD C 3050 integrated amp is a retro-audiophile component but loaded with new school technologies like HDMI. The $12,000 Classe Delta PRE also has full HDMI connections which is also rare in the audiophile world today.

MQA (Master Quality Authenticated)

MQA is a proprietary audio codec designed to deliver high-resolution audio in a compact file size. While MQA promises superior sound quality, the licensing fees associated with its use can be significant. Audiophile companies must not only pay for the right to use the MQA technology but also adhere to strict implementation guidelines. This can deter manufacturers from adopting MQA, leading them to explore other high-resolution audio formats that may be less costly to license and implement.

Dolby Digital and DTS (for surround sound)

Dolby Digital and DTS are widely recognized for their immersive surround sound capabilities. These technologies are ubiquitous in home theater systems but less common in high-end audiophile setups. The reason lies in the steep licensing fees and the complexity of integration. Both Dolby and DTS require manufacturers to pay for the use of their codecs and adhere to rigorous certification processes. This can be particularly challenging for audiophile companies that prioritize stereo sound and high-fidelity audio over multi-channel formats.

Room Correction Technologies

Room correction technologies like Dirac Live and Audyssey enhance audio playback by adjusting the sound to account for the acoustics of a listening environment. While these technologies can significantly improve sound quality, they also come with high licensing costs. The implementation requires advanced algorithms and sophisticated software, which can be costly to develop and license. Many audiophile companies choose to focus on optimizing their hardware and acoustics manually rather than investing in expensive room correction technologies. A good example of a company who spent the money on room correction is Anthem in their Anthem STR stereo preamp or the Trinnov Amethyst stereo preamp.

Why Many Audiophile Companies Avoid Certain Key Technologies

Audiophile companies often prefer to concentrate on their core competencies, such as high-quality analog components, precision engineering and sexy industrial design.

The high costs and technical complexities associated with licensing advanced audiophile and AV technologies can divert resources from these core areas. At least that is what many of the companies say.

Cost Considerations

The high licensing fees for technologies like HDMI, MQA, Dolby Digital, and DTS can make audiophile equipment prohibitively expensive. By opting out of these technologies, companies can keep their products more affordable and accessible to a broader range of consumers.

For billion dollar companies looking to add key technologies, a $25,000 to $100,000 fee isn’t the end of the world. For a more Mom-and-Pop operation in the audiophile space, these fees can be an absolute non-starter.
