Simaudio CD Player Technologies
Delta Suspension (Simaudio Ltd. Proprietary Technology)
This suspension acts as a decoupling device between the drive and the
CD player's chassis. It is accomplished through the use of a special
gel based transport mount that provides for exceptionally accurate
mechanical grounding. The main goal here is to dampen the vibrations
resulting from both the transport mechanism and the disc's rotation,
keeping in mind that the majority of CD's aren't perfectly centered
when they are manufactured. The result of the Delta Suspension is virtually
total immunity from all external vibrations.
Ambient and spatial cues in your recordings will come to life as you never heard them before.
Alpha Clocking System (Simaudio Ltd. Proprietary Technology)
Featuring PLL syncronization, this clocking system achieves extremely accurate
phasing and much better than average recovery of information from the compact disc.
As well, digital clock-signal integrity is dramatically improved. The result is
extremely low jitter in the order of less than 10 picoseconds RMS which means
the elimination of digital fatigue in the high-frequency region, and therefore
a more analog-like, yet very realistic sonic signature.
The significant differences, with respect to jitter, between a digital clock signal from
the Simaudio Alpha Clocking system (figure 6) and a typical digital clock signal:
Figure #6
When the width of the digital impulses (A, B, C, D, E, F) are identical, then the phasing between
the impulses (1, 2, 3, 4, 5) will all have same width, resulting in extremely low phase errors.
Figure #7
When the width of the digital impulses (A, B, C, D, E, F) are not equal, then the phasing between
the impulses (1, 2, 3, 4, 5) will vary noticeably in width, resulting in significant phase errors.
High-frequencies never sounded so natural ... cymbals so life-like that you'll want to reach out and touch them ...
a genuinely non-fatiguing sound without even a hint of digital grain.
