The Wavelength Audio Quotient DAC Module is a new upgrade for the Crimson High Speed USB DAC that has added DSD 64 / DSD 128 as well as support for PCM files up to 32/384 kHz. But the Quotient Q1 adds far more to the Crimson than just DSD and increased PCM sampling rate support. Gordon Rankin has gone back to the drawing board for this new DAC module resulting in a number of improvements for his flagship DAC.

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.

The Resonessence Labs INVICTA Mirus DAC represents the state-of-the-art offering from this Canadian company. The Mirus is closely related to the Invicta DAC that Michael Lavorgna reviewed in May 2013 (see review). Michael presented an excellent review that was quite thorough in describing the features of the Invicta. Since that time, a number of improvements have been added to the Invicta, including a new model called the Mirus. The XLR/RCA output specifications of the INVICTA Mirus outperform those of the standard Invicta. The headphone module is removed in the Mirus, and replaced with a second ESS Sabre DAC ES9018 for each channel. By combing 2 ESS Sabre ES9018 DACS in parallel per channel, a total of 8 ES9018 channels are available for each stereo output. Resonessence Labs has discovered that every time the Sabre DAC output channels are paralleled together performance improves. This feature results in a lowering of the noise and a decrease in THD compared to the Invicta. The dynamic range specification is also improved in the Mirus.

Fidelizer Pro 6.5 is the creation of an audiophile from Thailand by the name of Keetakawee Punpeng. Back in 2011, Keetakawee released freeware for Windows called Fidelizer that provided optimization for dedicated Windows computers working as music servers. His software was designed to improve the sound of music software playing on Windows 7 computers. The software was easy to use and did not make a permanent change to the operating system.

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.

exaSound Audio Design has managed to carve out a conspicuous place in the high end audiophile DAC market since beginning business less than 4 years ago. Michael Lavorgna reviewed the e20 MK III DAC for AudioStream (see review) and found it to do a fine job on PCM and native DSD playback. The e22 DAC is exaSound’s recently introduced flagship 2 channel DAC having improved on the design of the e20 MKIII to provide a superior level of sound quality. exaSound also builds an e28 DAC that can deliver from 2 to 8 channels of PCM and DSD.

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.
