I upgraded my Sennheiser HD 660S2 wired headphones with a more powerful iFi DAC to unlock the highest quality audio — but I honestly wasn’t expecting these results

Summary

The author upgraded Sennheiser HD 660S2 headphones with an iFi Zen DAC 3, expecting significant audio improvements. While subtle enhancements were noted, particularly in bass and clarity, the author found the results incremental, attributing the initial good sound to their MacBook's built-in DAC. Testing with a less powerful phone revealed a more pronounced difference, highlighting the DAC's benefit for less capable audio sources.

Credibility & Bias Reasoning

Credibility assessment: The article provides a personal account of audio equipment testing, incorporating technical details and specific song examples. While subjective, the author's experience is presented logically, and the inclusion of product specifications enhances credibility. However, the reliance on personal preference and the absence of broader scientific validation limit a perfect score.

Bias assessment: Enthusiast Audiophile. The author's deep personal investment in audio quality and the detailed, almost reverent, descriptions of sonic improvements indicate a strong bias towards high-fidelity audio experiences. The language used, such as 'highest quality audio' and 'loftiest realms of sonic sophistication,' reveals a perspective that prioritizes premium audio reproduction.

Note: This article offers a personal review of audio equipment. While detailed, the findings are based on the author's subjective experience and may not universally apply. Consider other reviews and technical specifications for a comprehensive understanding.

• The quantification of improvement as '5%' is an arbitrary and unsubstantiated estimate.
• The '5% improvement' is a subjective and unquantifiable assessment, lacking objective measurement.
• The phrase 'swear blind' and the generalization about 'plenty of people' are anecdotal and lack specific evidence to support the claim that it's 'not actually always true' in a universally applicable sense.
