AfterDark Queen 10MHz Master Clock for your EtherREGEN or Singxer - SU-2 for USB Stereotimes "The Absolute very BEST UPGRADE” available today! 30-Day Trial Period - Money Back Guarantee - Full 2-Year Warranty - Go to: 

Ok folks let me start by giving you a quick rundown.   

There is a lot of info on here but honestly you only need to read the top part above the line to get the full gist. 

The rest is just the rest.  
It all started for me one day when I was reading through a technical periodical and one particular article had caught my eye. The article jumped off the page, caught and held my attention. It was a sort of deep dive, tech based look at how hi-def video steaming could reap large quality gains by improving the network’s timing accuracy. Not by improving the camera lens or any other video hardware related change but the focus was on extracting these gains by improving the performance of the network itself.   

With so many applicable parallels to audio this really got me thinking. We all know the bandwidth demands for hi def video files are much more taxing than their corresponding audio files. If it can provide significant quality gains for video then what can it do for audio? I was intrigued.      

After doing a great deal of research and product beta testing I was lead to both the AfterDark Queen Master Clock which is the same model listed in this ad and the UpTone Audio EtherREGEN.  
The AfterDark PROJECT CLAYX GIESEMANN OCXO 10MHz Queen Master Reference Clock. This clock was purposely designed and engineered to be the perfect partner for the UpTone Audio EtherREGEN. The EtherREGEN is the only product I knew that could both accept a 10MHz Clock signal and provided a switch on the back that allows their internal clock to be bypassed so the master clock could take over all the timing duties for your home audio network.     

The combo of these two unique, specialty devices represented the perfect solution to accomplish the goal of mirroring the results the folks were getting over on the hi def video side of things. Needless to say, I was super excited. 

It was now time to enter this pair into my personal reference system. 

My system consists of:  
Ypsilon Phaethon Integrated Amplifier, Bricasti M1 Special Edition MDx DAC w/optional Roon Endpoint Player, Antipodes S40 Music Server with V5.2H Board,  Antipodes S60 (HLS-50) Hybrid Power Supply, Focal Sopra Loudspeakers and a full loom of Nordost Frey 2 cables. 
The rest of my system was already warmed up nice and ready to go. I then powered everything down and hooked up the AfterDark Queen Master Clock and the UpTone Audio EtherREGEN and then turned everything back on and fired it all up. 
I waited a couple minutes, not long but a few minutes for everything to settle in nicely and then I clicked on the first track and just sat back and listened.  

I was absolutely and utterly floored, amazed and totally blown away impressed! I just flat out could not believe it. It didn’t sound like the same audio system. I know this sounds over the top but it is the absolute truth. The level of improvement was absolutely breathtaking. I was laughing and so happy. I knew I struck a vein of unadulterated, full blown, untapped audio improvement and it was awesome! Song after song was just a full blend of goosebump generating, hair on the back of my neck standing up ball of could not believe it’ ness. It’s just that to be honest really good audio improvements are hard to come by and those are why we do this hobby. This one will know knock you out of your chair. It makes an power cable or preamp upgrade a joke in comparison. 
I was so psyched I was jumping around and my non-audiophile wife was looking at me like I was a lunatic! Lol... There was no doubt though, none. None whatsoever this was a legit audio discovery.  
Now at the time I was like hmmm? Will everyone else be so blown away? Am I just an audio nut out on an island? No way this is way too good? I mean I knew how great it was but I needed to get this out in front of more people. I needed confirmation. I was a little worried. It was like I was the only one that knew about this new secret. 

Well there was no reason for me to worry. Person after person had the same response as me.  
I can speak with even more confidence today. I have sold a bunch of these Queen Master Clocks and each person feels the same way. The emails and texts I get are great. 

Here are some snippets of emails and  texts.  
~ Frank you have to be kidding me - OMG this is good ~ unreal Frank ~ amazing Frank ~ Thanks so much for sharing Frank - absolutely unbelievable ~ Frank how is this possible ~ can’t believe how dam good this is ~ I will never question you again ~ how does everyone not know about these ~ OMG Frank ~ Frank are you serious ~ draw dropping ~ Frank you undersold it and what you wrote was borderline silly ~ unbelievable ~ incredible ~ does this goodness wear off ~ absurdly good ~ I would pay $10,000 for this ~ God Bless you Frank ~ I thought you were over exaggerating, I will never doubt you again ~ just astonished ~ flabbergasted to list a few!

All I can tell you is this!    
I offer a Full 30 day trial money back Guarantee. It comes with a full 2 year warranty and we have tons and tons of people all over the forums that can’t say enough good things.

This is the Facebook Review I just got today. This by Mitch. He is a reviewer and he is working on a review for us right now. I am not supposed to give up any details review so I asked him to post his thoughts on my Facebook page which he did. Here they are: 


Moreno Mitchell - Reviewer Stereotimes  

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.

We guarantee it or your money back!

None of us involved in hi-end audio be it any of the OEMs, dealers, distributors or even the super knowledgeable audiophiles fully understood just how much audio improvement was available to us via our own home audio networks? 

We just didn't know and honestly how could we have known? 

Many of todays Hi Fi audio devices such as streamers, network players and DAC's already perform many of the requisite duties of cleaning, re-clocking and making the bits from our home audio network sound great. The home audio network just wasn’t something anyone was looking at real closely. We thought everything was fine. In fairness, why would we have not? Our systems sounded great? It just wasn’t in our audio upgrade consciousness. 

We were focused on DAC chips and all the new emerging network based devices themselves but the network as its own discrete, individual entity was not yet on our radars. We know now this was a mistake but we didn't know that at the time. Hindsight is always 20/20! 

As network based streaming audio gained in popularity we naturally started to look at the network more closely. We started with the simple and most obvious upgrades such as improving our Ethernet cables and removing all the SMPS (wall warts) from our audio systems. We replaced the wall warts with linear power supplies. These changes seemed to help. In some cases we even added an upgraded or modified network switch and this seemed to push the performance even further. The important point to take out of this is the network was finally a legitimate area of focus. We were learning that we could obtain meaningful audio improvement from improving our home network. Truth be told these changes were just starting to scratch the surface. Real innovation is what drives real change in the audio industry and real innovation was just around the corner. 

The real change started to happen with the introduction of the outstanding Uptone Audio EtherREGEN. Alex Crespi and John Swenson, a couple of the audio industry’s brightest stars created a device that truly makes a significant difference. There was nothing else out there quite like it. It is a legitimate ground breaking device. Not only does the Uptone Audio EtherREGEN do a much better job at cleaning and re-clocking our home audio networks, they had the foresight to include a BNC Clock input. This input allows the EtherREGEN's internal clock to be bypassed so it can accept a much more powerful 10MHz signal from an OCXO Master Clock. This changed everything. It was an absolute game changer! Make no doubt about it streaming audio will never be same!  

The EtherREGEN's true brilliance was unleashed with a vengeance when it was tethered to a powerful master clock. The two working in tandem blew the boundaries wide open of what was thought possible. No one had any idea this combo could improve our systems like this! It is unreal!    

When you insert an industrial strength oven controlled crystal oscillator into your home audio network that would normally be found in a high tech manufacturing environment the impact on streaming audio is just breathtaking! An OCXO Master Clock is an incredibly powerful device. One much-much more powerful then our home network requires to work properly. That is the catch. We just didn’t know. What the network requires to work properly and what is the best for streaming audio are two very different things. So much more so than anyone ever knew! It was a true eye opener.

This in many ways is a true learning event for the audio industry. Employing this level of concentrated timing precision and accuracy has never been attempted like this before. The more precise and accurate the timing the more it sounds like analog. In this unique situation using a much more powerful timing device you would think it would sound more like better digital. That the sound would be cleaner, quicker, sharper and more dynamic. This is not the case. It sounds more natural and organic, more relaxed. The music sounds closer, more intimate, more delicate with some natural warmth while being more transparent with heft. It's totally different from what past experience has taught us. This hyper-clocked sound it addictive. It sounds like your listening to a better recoding. It strips off layer after layer and reveals a level transparency that heightens the entire musical event. Everything becomes closer and fuller like that of a master tape. It is digital music that doesn't sound like digital. It sounds like analogue, very good analog.  

Folks that have bought our master clocks and attached them to their EtherREGEN's ask me how I am the only one doing this. They are amazed. Asking why isn’t this on the cover of Stereophile? My response is simple. Because it's brand new, it an emerging technology, out on the bleeding edge but folks are starting to learn and learn quickly. 

Read the Stereotimes review he can’t believe it. He was blown away! 

The combination of these unique, specialty devices (EtherREGEN & Queen Master Clock) each performing their own very specific role allows digital audio to hit its true potential. This is digital audio at its very best. There isn't a CD player or SACD player on the planet that can compete with this. I don't care what they cost. This tech has made more then a few high end audio items obsolete. 

Prepare to have your mind blown!

We are just so thrilled with the customer feedback coming in.
Our UIO (units in operation) is growing and quickly. Many 
folks have been kind enough to share their 
thoughts and experience with us.  

Below is a few snippets from the emails, texts and messages: 

Frank this sounds amazing, unbelievable, how is this possible, can’t believe it, thank you Frank, OMG are you serious, unreal, draw dropping, Frank you undersold it and what you wrote was borderline silly, unbelievable, absurdly good, I would pay $10,000 for this, Frank I never thought this was possible, I thought you were over exaggerating, 
just astonishing, shocking, Flabbergasted and this list goes on. I am going to ask folks 
if I can share their full emails and texts to make it easier but honestly every single person 
says the same thing. 

They all say: 
It is so much better than I thought it would be. 
The concept behind mastering the network-based time domain is grounded in solid science, it is measurable and verifiable. Yet it runs contrary to how audio upgrades paths have traditionally come forth. The bottom line is this kind of increased sound quality has 
always cost a lot more money! Much more!

Not only is this an incredible upgrade standing on its own, but it is disproportionately inexpensive. If we based our prices on actual audio improvement our prices would increase 10-fold. The good news our products price for performance are industry bests and we only charge based on the device. This combination of very different, specialty devices has produced a result that has far exceeded what anyone thought possible. Our devices along with those of our friends and colleagues over at Uptown Audio are the best bang for buck components you can buy on the market today bar none!  Our Master Clocks and Linear Power Supplies vastly improve upon the excellent Uptone Audio EtherREGEN! You just cannot get this kind of Improvement anywhere else.

Sneak Peek

Snippets and paraphrase from Stereotimes Brand-New Professional Audio Review  

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 I had not experienced  before even by those that cost much more.

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.

The AfterDark Queen Master

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.

Linear Power Supply x 2

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
