Thanks for the insights, could you also highlight beside the depth and seperation, how is is the high frequencies and bass say, compared to the Crystek. Ciyld the Crystek have more high and tighter, punchier bass compared to the pure? For rock, pop music, does it still outperform the rest of the clocks tested? Thanks again for your work and videos!

Looking Forward to trying a set of these clocks in my stack nice to see you made a video about them

Looking forward to this video!

Nicely done! I've just ordered SCpure clocks and #91B Flagship Full function FIFO Re-clock DDC Streamer with S/PDIF AES/EBU output assembled and tested

I replaced stock clocks in old Audio-gd HE-7 for accusilicons 90/98 and the change was unbelievable. But that cost 200 Eur for both with work of the technician. If the clock weren´t so expensive I would try them.. Thx for the vid

Great job 👍

Thank you for your series; it's how i have been introduced to IanCanada products. You have asked about other impression of these clocks. I would add only that I find the Accusilicon pair to be more of an improvement than you have expressed in comparaion to the original clocks in my TransportPi Digi (w/3.3v block) - PurePi II system. I would not go back. Whether this relatively modest system is worthy of the SC-Pures is something I'll have to ponder.

THank you for the review and opinion Gaby. Very well done video. I wish we could actually hear the differences you were able to hear from the clock switching rig you built. Maybe use royalty free music for this purpose? THen again with the compression of YT it may be no point.

Really useful video, thanks for sharing your subjective thoughts!

For me the first time I see your KZfaq channel and I really like it a lot. Since a couple of days I also have the SC-pure clocks in place and they are powered 24/7. First impression were as you described. More details wider soundstage a bit bit more upfront. Characteristics I really like. The difference with the standard clocks are not subtile :-) At the moment the change a bit every day and are still a bit harse especially when playing Shostakovich symphonies. I didn't had that before, hopefully that will disappear. . Via other Ian stuff the signal is trough a TAD151A S1 and a tube end stage.

@Gabster Thank you very much for your videos, you convinced me to do a DIY project, your D6 streamer. Regarding the clock replacement, how to know if any of my other equipment will do the reclocking? I will be using a toslink connection from D6 to the Platin hub (with DSP for room correction) and via WiSa standard (24bit / 96Khz) to the Burchardt active speakers which have built-in DAC and amps. In short, should I notice any improvements regarding the clock or would the clocks be an overkill for my system?

I have about 60 ours on my SC clocks, and they are still getting better. The first ours was not so impressive (as expected), they sounded sharp and thin in the upper midrange. Bass is very good from the beginning, and so is detail and 3D. Soundstage is wide an deep. I think you nail it quite well gabster. I am hoping for still some improvement the next days. The clocks is powewed 24/7 from Ians UcPure mk III with the big Eatons 2.7v-3000F.

What about if you stop the 45 and 49 around is that an issue?

Great to see you built a board to test 4 clocks on the fly, first time I see such a thing. So if I get this correctly you can switch between clocks with a app remote?

How is comparing denafrips with diy dac ?

Thank you for the great video! If a person just streams max up to 4x 44.1/48 at 176.4 or 192 would you recommend the 22.5792/24.5760 clocks or the 45.1584/49.1520 clock combo?

Gaby - on the D11 did you end up using separate UC supplies for every v+ input (3 on the DAC and 1 on fifo) and for pi 5v and separately for the audio hats 5v? So 6 UC supplies?

Awesome video love the setup.... But do you think your big dac streamer still sounds better than the denafrips?

thank you for sharing, if you have time id like to hear more about why we need 2 clocks, what is the 45/49 you mentioned and if the 45 will get you going, is it a option to just have 1 sc pure and 1 stock vs 2 crystec for example ? you mentioned clarity, detail and soundstage in your experience with your system could you put a % or # to those differences as if you were taking notes for your own personal reference ?

This is a useful opinion to temper expectations vs the run of the mill clocks. Your point is valid that clocks are the last step. If you have a well resolved system and you listen critically then they are key in separating your DAC from average to exceptional. Also useful to simply get some insight into the pricing. This is expensive. Far more expensive than the first round of Well Audio clocks. I think we need Doede to compare them to WellAudio clocks for an opinion on the high end clocks. Frankly if they did not sound significantly better than the Crystek, then what's the point?

Hey Gabster, off topic but what eye glass frames do you wear? IC Berlin?

Hello. Could I use this Sonoff as an Amp switcher into the same speakers? I have a s. state and tube amp which I use for different mood/music. It’s a pain to swap cables. My Ayre is a differential amp where the Tube is not so I can’t use a regular switch as they all have their grounds summed. Thank you

Gaby, is it feasible to replace the clock(s) and DAC chip(s) in lower end or mid-fi streamers, music players and DACs to improve them? Is there a lot of engineering and witchery done around these devices or is it a matter of observing, "yep, same number of pins.. out with the old and with the new...,,". ? I have three devices that I would love to do this on. An old early model bitstream DAC That could likely benefit from a better clock as those have improved since its engineering. And I have two lower end all-in-one DAC/streamers that I would be interested in upgrading. There are micro soldering phone repair stores in my area that could easily do the job if it's a matter of just replacing a part with a better part.

Hello @Gabster... For some reason, a number of your recent videos have become 'unavailable'. Looking at videos listed at DIY Audio, it seems some have been made Private, whereas others have become Unlisted (ie. require URL to access).

Gaby, I have two questions…. 1) have done any comparisons of different PSU types with any of these clocks? And have you experimented with NOS or other filter changes on the dac chip with any of these clocks?

Greetings! Thank you for another informative video. I am thinking of following your steps to build an Ian Canada Streamer/reckocker with I2S output (Roon IntelNuc-> Ian Canada Streamer --> Denefrips Venus II). I wonder how much of an SQ difference can be heard between SC-Pure and the default FifoPi Q7II clock. 10%, 20%, or even higher improvement?

It is important to understand that XO phase noise varies quite a bit from sample to sample. I have some experience with getting clocks measured and sorted for phase noise, and what one finds is that close in phase noise (for example at 2 Hz) can vary by as much as +/- 6 Dbc for clocks such as the CCHD 957, or the NDK SDA series. I suspect there would be similar variations for Ian's Pure SC as well, unless Ian actually measures and sorts the individual SC crystals to verify performance to his standards. If paying ~$200, or more, for an oscillator it would be nice to know for sure that the sample one purchases will perform to the standards shown in Ian's published phase noise measurements (or better). Of course, Ian's Pure SC is the only SC cut crystal based oscillators easily available for direct swap in a lot of DACs or source components. I am going to pick one up for my DSC-2 DAC, which uses only a single 45.xxx oscillator for use with only DSD 512 input from my HQPlayer server. This DAC currently uses an NDK SDA series oscillator, which is the best performing, easily available, oscillator-but of course an SC cut crystal based oscillator can be expected to perform better than the NDK.

Gaby…thanks for this. Two questions…. 1) is the SC-Pure available now? ) Is the crystal completely shielded? No additional shielding needed?

Do you know of any 100Mhz clocks which could rival these? The main clock in my DAC is 100Mhz and I currently have an ABRACON AOCJY1 installed, but I haven't got any idea if there are viable upgrade options for it in the future. Thanks!

Very useful as far as it goes but the comparison that you really need to do is Ian’s clock vs Andrea’s clock. Have you any plans to do that?

How do I know if these clocks would work with my DAC? Or are they all universal and interchangeable? Is it difficult to switch them out? Thanks

Why not using USB async mode, please explain...

Hey @Gabster. I was exploring the internals of my Terminator 1 dac and it uses Crysteks 45/49M clocks. I believe Ian’s Sc Pure can be replaced inside of this dac to make it sound better. Why don’t you explore it? Making a YT video log about that mod would be brilliant for your viewers!!! Thanks.

Hi, interesting stuff, enjoy your videos. fyi, your roon link does not work, it looks like it may be for your log-in.

G, I found out the hard way, I had to have a DAC with a clock to play my CD transport. Best, D.

Would it be a good compromise to get the sc pure 45 and the accu 49?

You mention they are double shielded, this is not correct. The outer shield has a lip that clamps the oscillator housing to lower resonance. No double shielding.

I wish they made 16.9344Mhz 5v version for my CD transport clock ....

I have watched this video like 3x really want to build me a streamer/dac I normally just plug my labtop up to my denefrips ares2 or Burson composer dac ' (Tidal) what would be a good starting point for me Gabster ? I read schamtics on a daily bases i work on Multimillion dollar machines and Automated robotic systems i just stay so busy ! Never used a streamer just laptop and Cd transport Thanks Gabster

What clocks are on the latest q7 board?

👍♥️🫂

A Neutron clock seems better to me.　For example, " New Class D ".
