Moving Beyond The Bits
While some people still want to argue that "bits are bits" when it comes to digital data transmission, other people are looking at real-world solutions to real-world problems. I have a number of devices in for review that take aim at cleaning up our USB connections. While each offers a different approach and even a different set of solutions to more than one problem, the JitterBug is a USB filter. What is it filtering? The company states, "JitterBug’s dual-circuitry measurably reduces unwanted noise currents and parasitic resonances. It also reduces jitter and packet errors (in some cases, packet errors are completely eliminated)."

The Synergistic Research Grounding Block is a new accessory from Synergistic Research that allows one to make multiple ground connections to various products. More importantly, it applies Synergistic Research’s UEF (Uniform Energy Field) Technology to a grounding block for sonic enhancement. I decided to write a review on this product since it can be used with a number of Synergistic Research products I have previously reviewed that utilize ground plane connections. These include the Tranquility Base, FEQ (Frequency Equalizer), and the Atmosphere - Acoustic Wave Generator. What I found most exciting about these new products is that they can be successfully applied to most any component.

The Shunyata Research Venom USB cable is the only USB cable offered by this high end manufacturer of cables, AC cords, power distribution centers, and audio accessories. Most other cable manufacturers offer a range of USB cables with enhanced features at increasing prices. Shunyata research has decided to offer only one model with everything that they feel is important in a USB cable design. Given the very reasonable price of $125 for a .75 meter length, I was curious to see just how the Venom USB cable would compare to the other high priced cables I have reviewed in the past for AudioStream. Knowing Shunyata Research’s well recognized product quality and dedication to superior audio performance, I truly wanted to see how this cable would perform in my system.

WARNING: This review is written for audiophiles and true believers in the audiophile experience. Non-audiophile, bits are bits people, continue at your own risk!

The JCAT Reference USB cable is Marcin Ostapowicz and Josef Piri’s latest offering to the ever growing high end USB cable market. Both of these gentlemen are probably better known as the principles behind the popular Windows operating system software JPLAY. JCAT is the hardware division of JPLAY and offers a number of computer audio hardware products.

I Like Bluetooth
Audioengine makes a number of well-priced products that deliver their fair share of musical enjoyment. I favorably reviewed their A5+ speakers (see review) and we own two pairs of their original A2 speakers. Under inspection today is their B1 Bluetooth Music Receiver which adds Bluetooth connectivity to any hi-fi while also offering an internal DAC as well as a Toslink output if you already own a DAC you enjoy. What's the point of Bluetooth? Fun.

The Synergistic Research Atmosphere is a room acoustic enhancement device that allows one to modify and improve the perceived soundstage as well as the quality of the sound from top to bottom of one’s system; all of this totally controlled by an iPad/iPhone app. What is even more remarkable is that this task is accomplished without a direct connection of any kind into one’s system components. At this point, I’m sure most of you will want to know what Atmosphere is actually doing to achieve this control of the sound of our systems.

The PowerCell 10 UEF is the latest version of Synergistic Research’s PowerCell AC line conditioner first introduced in 2008. This version of the PowerCell is Synergistic Research’s most ambitious undertaking in dealing with AC line noise. The Power Cell 10 UEF not only adds Synergistic Research’s new UEF technology, but also allows one to employ the FEQ Equalizer first introduced in 2013 with the High Frequency Transducer (HFT) / Frequency Equalizer (FEQ) products.

The Hydra DPC-6 Digital Power Distribution Center is the first power conditioner made by Shunyata Research designed specifically for digital media products. Components such as computers, digital servers, disc-arrays, and cable modems-routers present special problems in terms of noise that pollutes the AC line that is simultaneously serving other audio components adversely affecting the overall sonic performance of our systems. Inexpensive power supplies with their minimal filtration provided with our hard disc arrays and computers produce a significant amount of digital noise. The Hydra DPC-6 electrically isolates these digital devices and provides a firewall to prevent them from polluting and degrading the sonic performance of the audio components sharing the power line.

Synergistic Research’s latest implementation of their Uniform Energy Field Technology, better known as UEF, has resulted in a new product designed to balance close proximity electromagnetic fields in electronic circuits. The product is called the Electronic Circuit Transducer or ECT. These tiny devices, approximately the size of the previously reviewed HFT (High Frequency Transducer), are placed on D to A chips, fuses, near vacuum tubes, capacitors, transformers, op amps, and analog and digital cables. The ECTs can also be placed on the exterior of the chassis to improve the electromagnetic environment of the component. Synergistic Research states that high frequency noise is reduced with a resultant drop in the perceived noise floor. Compression of the sound is decreased with application of these devices on your electronic components. Improvements in clarity and definition, along with soundstage size and air, are claimed to improve with use of the ECTs. The ECTs convert ultra-high frequencies that are found with RFI-EMI circuit board component emissions to more musically consonant frequencies.

Introduction
The 3 products under review all deal with common issues encountered in USB computer audio. Most USB DACs require a 5 volt line (VBUS) in the USB cable to supply power to the USB controller in one’s DAC. Unfortunately, this power line from the computer brings with it noise that can contaminate the audio data leading to degradation of the sound one hears from the DAC. The idea behind the Schiit Wyrd USB Decrapifier is that supplying clean power to your USB DAC, or better-quality USB port power management, can result in improvements in sound and performance. Schiit believes that glitches and dropouts can be prevented using the Wyred USB Decrapifier.

Isolation
For my review of the Focal Alpha 50 active speakers, my contact sent along a pair of IsoAcoustics L8R155 speaker stands, "I don't do a single demo without it." A few readers alerted me to the IsoAcoustics stands in the past but at the time IsoAcoustics did not have a set small enough to accommodate my ADAM A3X speakers and it was only until this pair arrived for review that I see IsoAcoustics has the ISO-L8R130 to fit their small footprint. So the idea of trying a pair faded until I admit I forgot all about them. All that's changed now that I've heard 'em.

When I first heard that Synergistic Research was bringing out a new USB cable, a thought occurred to me. Just how much better could this cable be made considering that the Synergistic Research Active USB SE cable was recently upgraded with the new UEF Tuning Circuits? The Uniform Energy Field Technology Tuning Circuits consist of the gray and silver cylindrical devices that attach to the active shield of the Active USB SE cable and fine tune the sound of the cable. I have found that the UEF Tuning Circuits provide a smoother, more revealing sound with enhanced bloom. But after reading about the Galileo series of cables, I discovered that this series applies Synergistic Research technologies not found in the Active USB SE cable.

Being an audio reviewer, I have the opportunity to evaluate many of the high end USB cables that are manufactured today. While most of these cables are very nice sounding, some of the cables really distinguish themselves sonically. The JCAT USB cable is just one of those very special USB cables that stand out from the large number of high-end USB cable offerings today.

The Overdrive USB DAC/Pre is the creation of engineer-designer Steve Nugent of Empirical Audio. Empirical Audio was formed in 1994 and initially concentrated on the sales of patented cable products designed by Steve Nugent. Steve’s background included a degree in Electrical Engineering with 25 years of digital design experience. His resume included work for the Intel Corp. where he served as a design-team lead in the development of the Pentium II processor. Steve has also been a passionate audiophile for over 39 years and this interest lead him into the modification of other manufacturer’s audio products in 2002. His modifications not only included DACs, but preamps, power amps and CD players / transports. The modification of numerous designs gave Steve a wonderful opportunity to see what sounded best in audio and DAC design. During this time, Steve developed the Off Ramp Turbo USB Converter; a device that offered a USB interface to digital products. In 2009, Empirical Audio ceased equipment modification and concentrated on original computer audio product design.

The Synergistic Research UEF (Uniform Energy Field) Technology Active Tuning Circuits are the new replacements for the Enigma Tuning Circuits (Bullets) provided with the Synergistic Research Element and Galileo Series cables and AC cords, Digital Power Tools, Tranquility Bases, PowerCell line conditioners, and older Tesla Series LE cables and AC cords. The Enigma Tuning Circuits or Bullets were used to fine tune the sound of the Active Shields in Synergistic Research cables, AC cords and active devices. I have previously described the action of the Enigma Tuning Circuits in my reviews of the Tranquility Base (see review), the USB Active SE cable (see review), and the Element C.T.S. Digital AC cord (see review).
