Whoops, it seems like I've mistaken UcPure and Parallel in that it was regarding the output side. Since I don't use Transformers, it was actually regarding Parallel on the input side.
Anyways, it's a bit fresh on my memory so I thought I try to document. My memory wipes out after a few weeks, so I thought I document for those wanting to parallel their UcPures in the future.
Parallel is more straightforward than having to figure out both Series and Parallel at the same time as with the Flagship LiFePO4 MKIII.
For experienced users whom know how to Parallel, this may seem trivial for those whom can do this within their Inner Monologue. But any hints, tips or confirmation for us simpletons will be appreciated. Once confirmed, I'll document this in the Power thread. Fundamentally Correct?

I look forward to newclassd impressions especially NS3 11 MHz.
I will plan obsolescence with either a duplicate DRIXO 5 MHz or NS3 11 MHz since my backup spare parts Q3/RCP system revolves around external.

Maybe 338 are fakes, I bought them from a chinese seller. They doesn’t sound bad at all, but the SC clocks is better.

thank you for this possible valuable solution, I have a pair of ACCUSILICON myself and every time I used them (FifoPiMa) the sound was not on and I quickly switched back to standard clocks because they sounded nicer.
I shortened the pins and walla, now they sound a little better than before, or is it my imagination...... let's listen for a while first.

Probably not just your imagination. Longer leads from the ground plane will increase capacitance and may affect SQ.
Ok thanks @smooth dancer , I'm just trying to get to the bottom of it, why there is such a discrepancy among mine and other users experience.
@roderickvd I'm more inclined to believe that it's more about the vibration control of the clocks themselves than the capacitance of leads, although that could also very well be a contributing factor, so thanks for your suggestion.
My own belief is based on experience that everytime I optimized the vibration control of my whole PurePi stack, it generated interesting gains. First nice upgrade was Audio Bastion X-Pad Pro pads (with ceramic balls inside). Then another was granite block as a base and under it went Audio Bastion Redline dampers to decouple. Now I'm using more sophisticated decoupler and planning to try even better pads.
My point is that with each upgrade, the performance of my streamer stack responded tremendously, which I'm guessing is by stabilizing the clocks, but could be also some other unknown mechanism.

Agreed, that can also be an important factor. As well as minimising airflow, if you're after reducing mechanical interference.
I’m still listening. I hear better base I think and deeper soundstage but it’s not huge difference from stock clocks. But not burned in yet. I’ve ordered a UcPure iIi to power the fifopiq7 and dac on the dac stack. Cause I have to keep us with you all now 😂 looks like a space shuttle rocket 🚀 booster set!
Re the pi that’s in my streamer stack. My dac stack is pi-less. So no noise coming from the pi and drive or monitor as it’s going i2S over hdmi to the dac via hdmipro.
I’ll keep burning and see how the ucpure works.
For those new or somewhat new to this thread, I just want to remind you the end of the Group Buy is likely approaching.
I believe Groups Buys only happen once every few years where you can get 10% off Ian parts you will likely end up procuring anyways.
So say Shipping Costs is $20.
As a baseline, spend $200, you break-even on shipping, etc.

Guys, I cannot make a decision which I/V hat I should choose for ESS9038 Dual Mono DAC:
1. IVSTD MKII (57 EUR) I have very good +/-12V PSU for it
2. TRANSFORMER I / V PCB Kit V2 and 2x DS2206 audio transformer 600:10 (60 EUR)
What is the con and pro?

I've been sitting here listening on the couch for an hour now with a big smile, the dark clouds are gone and the sky has broken open with a nice breeze.
this was clearly the problem, luckily but otherwise I would have almost made a watch out of it😉
Hello,
I remember the mounting instructions for the Italian clocks using a thin wire to kind of stop vibrations being transferred into the clock.
Here the clocks have a more tank like look with a kind of sturdy paws. If the circuitboard is trembling so will the clocks be trembling. You could add a piece of visco elastic material between the socket and the clocks ( like we use to have to mount a cartridge) or mount it as directly as possibly and take care the circuitboard isnt trembling.
Of course if you study the non audiophile " devices " designed to manage vibrations they will always give different specs for different types. A specific item will only work when " loaded " with a certain minimum and maximum weight.
There are brands who make fantastic products like the Japanese Taica . You could see the complete Canadian stack is one item and isolate this as it where one unit after all most boards are interconnected with gpio connection so firm attached.
Taica gives a lot of info on their products. Some of them available at Mouser.
Greetings,Eduard

I just had a buddy over to listen to my system. He used to be a sound engineer.
He was blown away. Said he hasn’t heard digital sound this good ever. He said “I don’t know what you spent on it but it’s the best sound I’ve heard”.
So I am encouraged that this is audible by others and it’s money well spent.

So what was issue ? Are you referring to the 4 ‘legs’ on SC-Pure or accusilicon clocks?
Hello,
He is talking about the accusilon clocks.
If you look at the clock like you look at a cartridge using lots of imagination.you will understand that you will need more than amazon spikes to get optimum results.

I’m getting there. I’ve only been in the game 2 months. The spikes are right now upside down on the DAC stack not even being used 😂 set into my plastic plate backwards which has some give actually…as there are four other screws holding the pure pi duo linear also to the plate.
The base is now the pure pi duo stand-offs. But I’m building a case. I can’t really finish that till I’m finished the final configuration of the DAC. I’ve just ordered ucpureiii and some yellow super capacitors.
You have to go easy on us guys with spikes and displays 😂 we’re newbie audiophiles - not yet purist extremists - but I say if gabster can get away with a display on his ‘worlds second best DAC’ then I should be ok too!
All in jest Eduard! I love your dry sense of humour!
So the rubber isolator goes under the clocks? Or you can use it with feet? Under the DAC ? I’m waiting for final burn in before I try and ‘fix’ the new clocks. They are in the same config as my default fifo clocks were in before I installed SCPure so it’s an equal competition right now as far as vibration in comparing against SC-Pure….

Please ignore the UcPure Parallel post, it was my mistake that I thought the discussion was output when it was input.
So I moved the post to the Power thread ready for those whom want to Parallel their output one day:
https://www.diyaudio.com/community/...epo4-battery-power-supply.327105/post-7464022
As for 3V vs 2.7V, the latest Ian documentation doesn't specify either 3V or 2.7 only 3000F:
So with the power of hindsight after knowing about UcBalancer operating natively at 2.7V, I would seriously just consider 2.7. I really wanted the 2.7 3400F for 5V since a little headroom for the RPi one day would be nice.
The clicking or switching sound the UcPure makes when it goes in and out of Pure Mode annoys, so an extra 400F will decrease that variance.
So going forward, I don't think there's a distinction between 3V and 2.7V just if it's 3000F+ concerning the Eatons.
A big But, only if UcBalancer is in the loop otherwise I would have to re-evaluate.

Hmmm,,,if the legs not have the exactly same length, the short one will not touch the bottom of the clock adapter, or maybe it is enough connection from the sides surrounding the pins ?
Hello,
I think the connection is being established the adaptor having some kind of spring connection.
Of course if exchanging clocks happens a lot and diameter of the pins are not identical you might end up with a less than tight connection. If not all the " signal " is properly transmitted the advantage of a better clock could be come smaller.
I remember a few French audiophiles soldering the input cable of their mc preamp or transformer directly to the cartridge.
With my diy amplification i will always skip plug/ output terminal on pre amp side. Save a little money but gain some fidelity. Clock mounting could be regarded the same way.
