📍 March V- M5: When Technical Obsession Meets Reverence for Sound - 1️⃣
Three Years of Obsessive Refinement: The "OCD Approach" to Digital Processing Part. The Non-Compromise Starting Point: Hunting Down the "Glitch".
When we heard the persistent high-frequency harshness, we realized the problem might not lie with the headphones themselves. Instead, digital signal "source contamination" could be the hidden culprit. Traditional solutions relying on computer or phone clocks allow jitter (time-base distortion) to infiltrate, much like sand in a water stream — no analog circuitry can fully filter this out.
Our Three-Pronged Solution:
✅Eliminate All Dependencies: We rebuilt the digital architecture using FPGA and dual crystal oscillators. USB, Bluetooth, and SPDIF only handle data transfer, with independent audio processing.
✅“VIP Channel for Signals”: The asynchronous transmission mechanism acts as a meticulous traffic controller, isolating source clock interference.
✅Custom "Purification" for Every Detail: From DSD512 to MQA decoding, LDAC HD to SPDIF clock matching, each input format gets its bespoke filtering process.
International reviewers have called this a "textbook example of jitter control." What we truly want to hear, however, is users saying: "I never knew the T1's highs could be this silken".
