FAIRFIELD, IOWA, March 17, 2011 – HEGEL Music Systems, world-renowned for high-performance audio electronics, unveils the HD2 and HD20 DACs, featuring what may be the world’s most advanced jitter reduction circuitry.
Jitter – What Really Matters
When assessing DAC performance, people often ask: “Does it run in asynchronous mode?”, or “What DAC chip are you using?”, or Does it run native 88.2 kHz?”
According to Bent Holter, founder and chief designer of HEGEL, these discussions subordinate the real issue: jitter reduction. Says Holter: “Jitter is what matters. A DAC chip can only work with what it’s given. If the data-stream is not properly synchronized between the sender and the receiver, even the most expensive DAC chip will fail to produce music.”
Holter continued: “Unfortunately, the common solution to jitter is to run DAC chips in so-called ‘asynchronous mode’. The problem is that, in most cases, it doesn’t work. Often, DAC’s in ‘asynchronous mode’ actually INCREASE jitter. Measurements prove this. Hegel’s approach is very different.
HEGEL DAC’s utilize a proprietary re-clocking circuit, with highly precise buffers and an advanced crystal clock developed by HEGEL engineers. This circuit HALTS the data stream, re-builds it, and feeds it in near-perfect rhythm to the HEGEL DAC chip.”
Holter further observes: “This not just a design philosophy. The results can be proven and experienced. Distortion is measurably lower on HEGEL DAC’s, due to attention placed upon jitter-reduction.
The finest test instrument, the human ear, is unerring. With reduced jitter, listeners immediately notice the absence of distortion and greater tonal purity. But…the most striking result of jitter-reduction is: Enhanced Bass. With HEGEL DAC’s, listeners are surprised to hear another layer of clean, powerful bass emerging from pure silence”.
