.? Digital Reclocking and syncing clocks does anyone know the correct Answrrsb


Hello To all ,many Audiophiles I have found do not  even know what a Digital reclocker is, and what does it do exactly , and how it helps the incoming signal.

and the Bigger question is Syncing  the clock to Dac.

for example with Denafrips Reclocker , the most versatile I have seen with input outputs especially from Hermes, Gaia DCC reclockers  most inputs,outputs,       they have both   45,and 48 MHZ  for clock sync. ,other dacs clocks may use 5-10 MHz  ,this gets a bit confusing.
Here is a big question , say you have a very good dac with over clock ⏰, 

Is there any advantage to syncing clock say from cheaper Iris DDC reclocker  ,to the  very good say Terminator oven  controlled clock. The Big  question is how does this work? Does the better clock in the dac dominate or influence  the lesser  clocks ?

or don’t bother syncing clock with cheaper Iris DDC ?  Do you have to have a reclocker with = quality ⏰ clock  to the dac to  make it  a Sonic improvement ? 
these are the questions  no one I know has been able to answer with absolute knowledge.

just the reclocker itself is worth wild for. It filters and cleans the incoming digital signal ,through usb,BNC,or coaxial cable, then reclocks signal to dac to have a pristine signal to read.. in this respect even a good basic reclocker like Iris would be very good ,on pontus and even Venus dac ,and Holo springs worked well 

for $600, next Big step the $1250 Hermes better everything including oven controlled clocks ,if you can afford it.  Syncing clocking is the big Question is there any benefit going from a lesser Iris clock in the Iris DDC reclocker syncing clock to say a Terminator + with far superior oven  clocks?Is there any benefit ? If so why ?  Thank you to Anyone who may have the expertise to logically explain this.
Hopefully Alvin Chee will see this ,Happy listening to  your music .🎶 🎵

In my new Denafrips terminator-2 it has A Ton os superlative parts , massive 

power supplies, excellent top notch filtering-Swiss Elna Silmic capacitors,

as well as SuperCapacitors , O core transformers , pre buffering, FPGA 

$$ Dual frequency 45,49 MHz Oven controlled clocks , and  I read the report on the Gaia ddc,  I am using the lesser Iris and it bypasses the ddc clock for the top Terminator-2clock , this mk2 model is just a few % points ofthe T+ model .

it is identical on 98 % j. Just a few more smaller filter caps .

and using good cables ,using Wireworld best silver sphere Hdmi-I2S , and silver starlight 75 ohm BNC cables to sync master clock in T2 you can clearly hear the difference in coherence. All 5 of my guests heard the difference with ease 

The holo May is very good , the Terminators have been improved as of April 2021

and in one specific better measurement in one area ,many times not quite as good as others ,they both sound excellent in their own ways..  Reclocking cleans  digital signal  and makes it easier to read when the dac get the data puts it in a buffer then does a bunch of other things before final conversion ,in good dacs a lot of information way over my digital knowledge base .

The master clock helps only if in your dac it’s not of equal or better quality.

i seen response from engineer Alvin from Denafrips he said in New Terminstor2,and plus model the terra clock no advantage pretty equal ,

 but reclocking , and syncing clock is worth doing , not enough space to include all in one box that's why it’s separate box, as well as for RF, isolation.

I was told the terra master clock is not worth it for New Terminator-2 which is pretty much identical to the Terminstor + but difference is the 1k R2R resistors in both 

are even better spec then .005 in terminator2 , hand specked boards and rounded front ,I felt being within a few %  save $$ and buy a decent reclocker 

will ping up to the $1250 Hermes with has over controlled clocks  be a noticeable upgrade  ? And syncing clocks is this a minor  improvement ?

if I bought a mytec how would I sync there clock to Denafrips that use   45, and 49 MHz ? It can get complicated  it’s kind of a grey area , Thanks guys fir the input it’s a area most Audiophiles have not yet ventured out into the unknown.Many times 

if we don’t understand it we tend to just avoid it ,when in fact if we know how it works, and improves the fidelity then much more likely to buy it .

this is where  MFG companies should sharpen their skills to include information on a product such as DDC reclocking , and advantages and how to sync clocks to other brand dacs.

To big_ Greg. The link you sent is in German which myself don’t know 

can you translate in and resend ? Thank you .

Just received from Denafrips 

The DDC is mainly to resolve the interference of the USB transmission potentially induced from the USB host (computer/streamer).
Such interference/noise is difficult to be handled & eliminated by the DAC itself due to the spare constraint.

DENAFRIPS DDC improves the sound quality from three aspects. One is to reduce the negative impact of the computer front end on the audio system, the other is to improve the negative impact of the power supply, and the third is to minimize the impact of the clock on the audio system.

The following reviews might be of interest to you:

If you use USB primarily, the DDC will be an improvement to the system.

Hermes is certainly a step up for the Iris. It uses OXCO (Iris uses TCXO), a trickle down of the Gaia DDC. In fact, i just filmed a video a few days ago, yet to publish.

Hope this helps!

 

Many thanks.

Reclocker works great for even decent streamers are far from a noise free environment ,try s good reclocker ,then you will see 

if using a computer a must ? As well as a uptone Ether regen on the Ethernet input 

noticeable improvement.

For anyone to say jitter which are timing errors are totally incorrect , even though the signal arrives in packets , the timing  can be off , distortions elsewhere substandard filtering, power supplies ,regulation pre,and post .

this is just a Bit of the potential whole. My uncle being a digital in pro audio for over 30 years ,has really  opened my 👁 👁 s  to so many  possibilities ,there is no one 

implementation that is best ,for everyone’s perception of correct in their specific 

system maybe different then you . 40 years + in audio and I am just looking into a DDC unit. I just started using Roon and streaming ,digital has truly evolved a lot in the last 3-4 years.digital has finally arrived !!

Cindyment I totally understand  there are Waay to many arm chair experts.

one thing is for sure the best measurements don’t always sound the best .

A perfect example A vacuum tube amp,or preamp measure no where near as good as even a mid fi amp but it’s distortions being even just sound right to the ear 

with audio and R2R dacs and DSP and FPGA ,buffering you can truly make great sounding digital. The older Terminator was still very good ,the New Terminator2 

which I recently purchased sounds Very good across the board and natural .

the DDC unit does clean the digital signal coming in . My friend has the Hermes almost exact Gaia clone and when connected I2S to terminator everything goes up a notch in sound , and syncing the clock is less so but soundstage deepens and wider from my experiences with it , nothing is perfect in Audio Ever !!

 

LordMelton  you are correct your 👂 ears are the best measuring tools 

graphs and specs do count when designing ,but there is ways to smooth out a ripple or spike ,and smooth things with oversampling FPGA ,the final result is how does it sound  to reality ,and your audio system ,as well as room will influence the sound .Sound is just a movement of frequency in the realm of time .

The Moody Blues Classic nights in white satin  in the orb summed it up best - We decide which is real and which is a illusion  !!

What I meant to say is  the digital stream is never perfect, But the much more costly units  have many ways to correct Jitter or timing errors ,

this too is where a DDC  -Digital to Digital converter to clean up the incoming digital stream and eliminate timing errors before it goes out to the dac , the easier the dac can read the less error correction s needed , On the better units they buffer the signal ,like ram  ,there there is FPGA  ,it’s exact implementation is above my Digital 

pay grade ,I just want to get the most natural presentation without breaking the bank for myself the Terminator-2 and a good DDC reclocker is good enough for me for the next few years , this too can be improved upon. I just installed a dedicated 20 amp line dual ground, now maybe a few grand for a power conditioner, better power cords , better 75 ohm BNC cables to sync the dac reclocker, and better I2S cable, better ,usb cable ,better Ethernet cables ,Everything counts, where does it 

all end ? Being an Audiophile  maybe it doesn’t !!
