An All-Out Assault on Jitter
I absolutely loved the AfterDark OCXO Clock, Linear Power Supply, and Black River BNC digital cable products so much for what it does in my system. The improvement in my system was profound. It transformed my digital front end in ways not experienced with past.
It all came together recently since I bypassed the internal clock in the EtherRegen with the AfterDark OCXO Clock.
It clearly demonstrated how important the accuracy of the time domain has on our home Ethernet network in the reproduction of music. With the significant reduction in digital artifacts, transients were reconstructed with superior stability and rhythmic integrity, presenting individual instrumental attacks with remarkable clarity. The music's overall pace and timing became more natural with AfterDark Clock, Linear Power Supply, and Black River BNC digital cable installed.
Once I swapped these into my system, I was hearing things I had not heard before. I was hearing further into the recording, appreciating a surprisingly large increase in microdynamic contrasts and bass articulation. The double bass response was tighter and displayed significantly less overhang.
The piano displayed a greater sense of space and depth within the soundstage and possessed a more natural tone. I also heard a greater weight of the piano, enhanced pitch definition and more complex textures from the double bass. The improvement in my system was profound in ways not achieved by tweaks, isolation, cables, etc; the impact of a dedicated clocking system was shown to be at the heart of digital reproduction.
There was also added weight to the music while the music took on a greater sense of realism. Given the added sense of space with nothing between you and the music, I had no thoughts of going back to the internal clock in my EtherRegen. My digital front end was transformed. The value for the dollar of this upgrade is in the absolute upper echelon of upgrades you can make. I loved the AfterDark products.
I immediately purchased the review samples.
My highest recommendation.

This is the current iteration of my personal audio system. I decided a little ways back to move away from analog audio entirely to focus solely on digital.
I have a couple new digital additions I’m super excited about.
The first is the new S-Series from Antipodes. This series features their new flagship OLADRA sound engine tech but at a lower price point due to coming in a half width chassis and offering the upgraded power supply as an option sold separately.
I purchased the S40 Music server/player that features the V5.2H music engine also found in the much more expensive K30. All the performance with a lower cost.
To maximize the S40‘s performance I also purchased the optional, Antipodes S60 HLS-50 hybrid switched linear power supply. It is the same power supply built into the K-Series flagship models yet in a modular, eternal version with dual power rails. This power supply tech is a huge step forward for Antipodes and it is tuned for speed and precision.
My other recent addition was the special order AfterDark Emperor Double Crown 10MHz Master Clock (75Ohm, SinWave) with Mini-circuits BLP-75+ low pass filter. The combo is an absolute revelation. It’s the main reason I decided to move on from analog audio. When digital audio sounds this amazing it has for all intents and purposes made analog audio obsolete. Well, in my system anyways it has.
I included the full details of my system below. Please share with me any recommendations, comments, feedback or even criticism.
I hope to hear from you.
Thanks for your interest. I truly and genuinely appreciate it.

Oven Controlled Crystal Oscillator Basics
An OCXO (or Oven Controlled Crystal Oscillator) is near the top of the food-chain when it comes to quartz-based frequency control devices, superseded only by the mighty DOCXO or Double Oven!
An OCXO is a temperature-controlled device that maintains a quartz crystal's constant operating temperature. This prevents changes in the specified frequency due to variations in ambient temperature.
The frequency output of a crystal oven is dependent on the temperature of the quartz crystal. You can see in the figure below that temperature can have a significant impact on frequency of the oscillator.

Today’s available digital converters, clocks, and audio re-clockers perform acceptably well reproducing or processing digital audio. Even so, we at AfterDark along with our North American partners on the Charles River, Ctronic Music Boston felt the existing products that enhance digital playback, OCXO clocks and linear power supply solutions are way overpriced. We knew we could bring a line of products to market at a much lower price while substantially increasing digital playback performance. Just look at how exceptionally well our products measure and the subjective consumer and reviewer response has been nothing short of astounding.
We are proud to offer this high fidelity, precision audio device at an unrivaled price. The performance per dollar cannot be matched. It has made traditional audio upgrades obsolete. You do not want to spend money on any traditional upgrade before you add an Uptone Audio EtherRegen and the Queen Master. If needed the Queen Masters side kick the LPS x 2 if you do not already own an LPS. They make humble audio systems dramatically better, and they make ambitious system improve a great deal as well. It is a very satisfying product offering.
In our commitment to advancing the state of the art and science we set out to investigate the possibilities to further enhance the performance of digital audio systems. To do so, our R&D team set out to build the very best clock we could. That ended up being the Emperor Giesemann EVA clock. This clock measures Phase Noise@ 10Hz -145 and Phase Noise@ 1 -121. The Emperor Giesemann EVA is the clock we worked from to develop the Queen Master. The Queen Master reflects many of the lessons learned and employs much of the same technology as The Emperor Giesemann EVA.
The AfterDark R&D team developed a master clock generator with a technical performance beyond what we thought was possible for the price. The result of the Queen Masters performance was then verified by a group of experienced audiophile beta testers to ensure the hard work translated into best-in-class sound.
The end result of our extensive efforts is the Queen Master: a superior 10 MHz reference master clock with a price to performance ratio unrivaled anywhere combining uncompromising engineering with the beauty of simplicity and the utmost clock precision.
A well laid-out main linear power supply constitutes the basis for exceptional high-end product performance. To meet this requirement, we specifically designed for the Queen Master a dual rail linear power supply based on a Nuvotem Talema Encapsulated Transformer: 25VA with Fast Acting Fuse Protection. It features two simultaneously driven voltage output jacks to power both the Queen Master and the Uptone Audio EtherREGEN. It provides Phillips BC 2200uf/25v x 4 Reservoir Caps, total of 8800uf and AC Noise Filter: UK RIFA RFI Suppression Caps & Noise Filter for the best suppression for the supply voltages. The Incoming AC: Japan Made EDK Switch / Furutech IEC and Schurter Gold Fuse for Audio Optimization, High Speed Rectifier with RIFA 0.1uf Bypass Caps. It has Phillips 1% Precision Resistors, Panasonic FC 120uf, 390uf Decoupling Caps, Mexico Made premium Inductors and Analog Device OP177 for Voltage Error Feedback Compensation and a Toshiba Pass Power Transistor. It is housed in a high-quality Integrated Aluminum Heat-sink chassis with premium Carbon Fiber 6mm/1mm Front & Back Plates. This premium, quiet power supply is the perfect partner for your Queen master and Uptone EtherRegen. You choose a fixed voltage that is the same for both rails from Voltage Ratings: 5VDC/3.5A, 9VDC/2.5A, 12VDC/2A, 19VDC/1.5A, 24VDC/1A. Default is 12VDC/2A.
The Queen Master is the new King of Hi Fidelity audio. You can also find us on Audiogon and US Audio Mart.

The AfterDark OCXO Clock and Power Supply took my present streamer to another level that I never imagined possible. After adding the popular EtherRegen to my system, I was completely amazed by the improvements in sonics, however upon adding the AfterDark clock and power supply it was "game over". The music immediately became more naturally relaxed and organic.
It was like listening to a different system, everything became so naturally transparent and spacey. The sound stage became enormous, every instrument had weight that transformed the music into a lifelike venue. Voices became more velvety and pronounced with a sense of purity and realism. Never would I have suspected that adding the AfterDark OCXO clock and Power Supply would bring these types of results and unforgettable musical joy.
A must have in the world of streaming music.
