Why Low Jitter Clock?
A low jitter clock is nothing new in the Hi-End Audio Market. Just search on the Internet and you will see more than a dozen of these products. Brand names like Audio clock that must not be named. Each tries to justify charging you an arm and a leg (up to $500 for a clock and $200 for a power supply board) and promising walls disappearing around you once it's installed.
So what is a Low Jitter Clock? And why will they make improvements to the Hi End audio and video system?
In every digital system there is a clock (the technical term is Master Oscillator). The function of the clock is to provide a benchmark. (A ruler if you like). It tells the laser pick-up if it is spinning too fast or too slow, so it will adjust itself. It also provides a benchmark for sampling digital signals from digital sources such as CD's, SACD's or DVD's.
So as you can see, if the benchmark is not accurate then the result is what we call Jitter Error. Brand names such as Arcam Alpha, Musical Fidelity, Meridian, Greek and other Hi-End brands are obviously aware of the benefits of a low jitter clock. However due to the cost concern, they will only incorporate low jitter clocks in their top of the range models. Apart from the cost issue, Jitter Error has only been identified as a deficiency in the last couple of years, therefore any CD player that's more than two to three years old will not have a low jitter clock in it. So installing one of our Burson Low Jitter Clocks is a shortcut to bring older digital source in line with some of today's best technology.
Most of the CD players being sold in the shops come with a simple clock, which is a combination of a single crystal and two capacitors. The typical error rate on this kind of clock is about 250 ps or more. Not only that, their performance is also very unstable, and can easily be affected by their surrounding temperature.
Team Burson spent many weeks on developing The Burson Clock. The clock is made from the best material we can source; Elna Capacitors, extra thick gold plated PCB, DALE military graded resistors. Also, each of the Clocks is carefully assembled and tested by one of our members. Before dispatching we have to fine tune each clock to ensure it is producing the most ideal square wave for the best performance.
We think charging $500+ (like audio clock who must not be named) for a simple circuitry is ridiculous. Please see some of the impressive features that the Burson Clock has to offer.
How Does It Sound?
The effect of the clock is instant; you don't need to "Burn In" to hear the difference. However, after burn in the clock will work even better. By reducing the jitter error, you will hear clearer positioning, also details are further refined vocally and instrumentally. Sound stage and positioning will improve noticeably and that includes deeper sound stage and darker background. Some say it also improves the control on the bass. However our experience tells us that may vary depending on the design of the rest of the machine.
How Do We Stack Up?
We have done comparisons with some of the leading brand names in the market. We can't disclose the technical results on the Internet for obvious legal concerns. However some of the so-called "2ps, even 1ps" " Low Jitter" claims, we found to be exaggerated. Our listening test confirmed that we couldn't detect any differences between our clock and those costing five to six times more. If you can detect any differences, please let us know.
