I sure wish Paul Hynes would update his website to provide more information.  I am sure he is getting flooded with inquiries.  Is there a better source for information other than his website?

 

Yes, I'll share it with you via pm in a bit.

??  Private information?  On a manufacturers website?  So strange ;)

Sure when I get home in an hour. 

 

If anyone else wants it PM me directly. 

I'll also copy paste in here or create a new thread. 

Thanks.

Thanks for your answer @romaz.  I was trying to figure out a way to avoid rehosting the sCLK-EX board, but your points are compelling.  I'd feel a lot more comfortable about all this if SOtM was planning to provide service in the USA in the future.

 

Where are you putting the sCLK-EX board with the clocks for your PC components?

 

Agreed about service in the USA but it probably won't happen as I think Lee is personally responsible for all the work that is done.  The quality of his workmanship, however, is top rate.  

 

What SOtM is offering, if you think about it, is revolutionary.  How many audio equipment manufacturers will perform mods like this for you?  It opens up so many unique opportunities.  We now have the ability to convert non-audiophile devices like switches, routers, motherboards, I/O cards, etc. into world-class audiophile devices without having to necessarily pay audiophile prices.  And it's not just about replacing clocks but also replacing noisy switching regulators (for $50 a piece) and adding or upgrading capacitors (for $20 a piece) without ever getting your hands dirtry.  On top of that, all work is guaranteed.

 

With my motherboard and I/O cards, the clock board will be mounted just adjacent to my motherboard so that I can get by with short (20cm) clock cable lengths.  Here is a photo:

Not sure if anyone were having serious balls to mod Chord DAVE as well as DAVINA in the future?

 

It's not something I would attempt but if you know someone who decides to do it, I would be interested in their findings.

A direct comparison of ISO REGEN vs tX-USBultra is still a key thing for me.  

 

My guess is that people will find that the two will perform very close and one may be better than the other depending on personal tastes and your system's needs.  The fact that John and Alex obtained an eye diagram for the ISO Regen and confirmed the integrity of its USB output says a lot.  People assume their USB output (which includes the integrity of their USB cable) is high quality based on what they hear but to really know that your USB integrity is as good as it can be, you need to get an eye diagram of your USB signal at all the bitrates that you listen to (Redbook and higher) and so in my view, the fact that they have done this is a big deal.  

 

If price is a high priority, I doubt you can beat the value of the ISO Regen.  If you are looking to clock a stack of components and desire the future option of adding a master clock, then SOtM is your only option.

 

Regardless of which path you take, I don't see any losers here.

I am going to order one but i told paul to design a better chassis like streacom FC9. my problem is bad looking chassis of SR7

 

I can say that the SR7 chassis looks much better in person than in photos.  I can also say that I prefer the black anodized chassis more.  Regardless of how it looks, it is a very solidly constructed chassis.

Here is what Paul will be posting on his new website.  Based on questions I had regarding an order for another DR SR7, he sent this to me just a few days ago:

 

 

Paul Hynes Design

 

SR Power Supplies

 

The SR range of high performance power supplies were designed for powering both analogue and digital audio and video equipment. The same proprietary ultra low noise high performance discrete component voltage regulator circuit topology is used in the SR3, SR5 and SR7 power supplies. The SR3 uses a standard 50VA mains transformer, the SR5 uses a custom manufactured 160VA mains transformer and the SR7 uses a custom manufactured 250VA mains transformer. The SR7MR uses a custom manufactured mains transformer with up to 350VA rating depending on the overall rail requirements. The custom manufactured balanced mains transformers use oversized grain orientated silicon steel cores and are wound to avoid core saturation in use, to provide high common mode noise rejection of mains interference and leakage currents, and to operate quietly both electrically and mechanically. Schottky Barrier rectifiers are used throughout the range, as they do not generate reverse recovery transients and their associated harmonic distortions. The rectification is configured in balanced mode to take full advantage of the balanced mains transformers and to enhance common mode rejection of mains noise and leakage currents.

 

The error amplifier used in the voltage regulator modules has the following specification :-

 

Noise voltage < 0.5 nanovolts root Hz

Operating Bandwidth > 300 Mhz

Supply line rejection > 80 dB DC to 100 KHz

Output impedance < 3 milliohms DC to 100 KHz

Transient response and settling time < 100 nanoseconds

 

As the SR3, SR5 and SR7 all use the same high performance regulator circuit topology they all have a similar sonic signature musically. Moving up the range allows better quality lower impedance mains transformers and up-rated rectification and regulator output stage providing a reduction in power supply output impedance, which in turn reduces interaction with the load. The increased energy storage capacitor bank also reduces rectifier ripple noise and RFI break through from the mains supply. Another benefit of the increased energy storage capacitance is with transient response and settling time. The net effect musically is to provide progressively larger, more stable and more robust soundstage particularly where large dynamic load current swings occur, as well as a lower noise floor and improved timbre and temporal accuracy.

 

These power supplies are available with fixed voltage output from 1.6v to 30v or variable voltage output with a 10 volt span on voltage setting, within this range, using the precision adjustment potentiometer internally situated on the regulator module.

 

Continuous power output ratings – For fixed output voltage versions the SR3 provides 25W, the SR5 provides 80W and the SR7 provides 125W and the SR7MR chassis can support up to 175W spread across the rails. The SR5 can support one 6A module and the SR7 can support one 10A module. The output voltage and output current can be specified within this power rating using the formulae :-

 

V = W/I

I = W/V

 

Where V is output voltage, W is the available power in Watts and I is the output current in Amps.

 

If you require help with power supply specification I will be pleased to help you.

 

For variable output voltage versions of the power supplies, set at the maximum output voltage of the range, the SR3 provides 25W, the SR5 provides 80W and the SR7 provides 125W. Lower voltage settings than maximum will increase the voltage across the regulator output device, which will increase the heat generated in this device. To maintain safe operating temperatures and long term reliability the current rating should be de-rated by 8% per volt when reducing the output voltage level on variable output voltage versions.

 

The SR5 and SR7 power supplies are available in Multirail versions SR5MR and SR7MR with galvanic isolation between the supply rails to avoid ground return current intermodulation (ground loops) where more than one item of equipment is powered from the same power supply. The SR5MR can support one 6A regulator module and one 3A regulator module or two 3A modules. The SR7MR can support one 10A module and up to two additional 3A modules or a 6A module and up to three additional 3A modules.

 

XL ultra low impedance (< 1 milliohm) connectors and fine silver internal DC wiring between modules and the output connectors, can be fitted to the SR3, SR5 and SR7 power supplies.

 

The SR3, SR5 and SR7 single rail supplies are also available in DR versions where two of the high performance voltage regulators are cascaded to a give supply line and rectification interference rejection exceeding 150 dB from DC to 100 KHz. This provides lower overall noise levels than the standard power supplies and better dynamic performance. The SR3DR, SR5DR and SR7DR can support one DR rail and the SR7DRMR2 (four regulator modules in total) can support two DR rails in the SR7MR4 chassis.

 

Power supply dimensions are :-

 

SR3 – W = 110mm, H = 50mm, D = 170mm

SR5 – W = 224mm, H = 90mm, D = 260mm

SR7, SR7MR2, SR7MR3 – W = 224mm, H = 130mm, D = 260mm

SR7MR4 – W = 224mm, H = 130mm, D = 340mm

No need for me to pm anyone now, Roy's covered it in this last post. Might want to consider pulling his account info.  While it's essentially one of his methods of payment and common knowledge to his customers, he may not want it on a public website.  I could be wrong though.

In hindsight, I probably shouldn't have included certain information although it doesn't appear I can edit my post.  I obviously just cut and paste what he sent me without trying to edit it although he told me this document will be going on his new website so it doesn't appear he intended for this information to be private.

And if our piece--with its galvanic isolation and USPCB for direct placement at the DAC--comes out equal or on top, will you guys complain if I triple the price to match at $990? x-D

We'll just buy more of them and you'll expand your customer base if you keep your price reasonable.

You still have to add 3 clock outputs available for it to be competitive :D.

I just want to compare the sCLK-EX to the Crystek 575 in the simplest possible way, without the complications of an SOtM modded switch or multiple reclocking devices in the chain.  

 

The SOtM pricing makes no sense unless you utilize all 4 clocks on their sCLK-EX board, and then you have several interdependent components because of the shared board.

 

I'm very happy with my ISO REGEN/LPS-1.

Sounds good, it shall be interesting to compare performance when I receive my SR7MR4 all 12V, this summer.
