Without going off topic too much, so far only NADAC is using it. It does not have many data point. On paper, it looks good but it is the same when one first uses USB for audio.
Golden Gate DAC arrives.

My feedback is for the open minded. So please speak for yourself if you don't like the valuable tips I share.
It's the best system yet for many reasons. But yes off topic for this thread. I suggest my interface thread if you want to further discuss Ravenna.

I am afraid I am not only speaking for myself but apparently that is rather difficult to comprehend.
It is not a mod, its an upgrade. The entire PCM design was changed. Nothing of the old remains.
The guys have a point. You have mde your point and keep hammering away to the point where you start to get disrespectful.

wisnon...Given that the factory modification to PCM playback has been very well received from what user feedback we have had thus far, I wonder whether Lukasz, is, or has been made aware of Blizzards points of view, and if so, whether he considers them as having any merit in any future development of his current DSD implementation?
With regard to the latest PCM module, is this currently only available, and applicable, to SE and not Balanced units?

You are just repeating your arguments in a circular way, avoiding my main argument - it is your unknown and non described experience and that of unknown DIY people.
IMHO you are using the jitter argument as a miraculous cure, exactly the same way some people use the argument of minimizing distortion or noise.
My point is that results you obtained in other equipment in non reported conditions are not forcefully transposed to all other similar equipment. The people from Lampizator are not ordinary DIY moders. They have large experience with the product, they had the opportunity to listen to it in many SOTA systems around the world, and a known background. Until we have their opinion I think there is no reason to carry a change that invalidates warranties and involves soldering.
If your advice was just a simple swap reversible in ten seconds, such as a tube swap, that can be done and reverted how long I we wish, I would not be so conservative - I also enjoy tuning.
We had a similar affair in the SoundLab forum years ago concerning the back plates. A few DIY modifiers started modifying the standard crossovers, optimizing it to their specif systems. Although the modification had some good consequences, it also had a few problems with some amplifiers - they could result in abundant smoke emission in some cases!
Roger West, the Soundlab onwer and designer, tested the mods, become aware of what could be improved in his own design, and later incorporated the results of this research in a new development - the Tooroid II. Surely I was one the first people to ask for it, as soon as it got the official approval seal. I hope that soon we will have the opinion of Lampizator people on these matters. Perhaps they will agree with you and offer an option similar to your advice, who knows?
My B7 is being upgraded , will have new pcm R2R within a few days, hopefuly for the weekend.
Assuming that Blizzard is right and a better clock with Amanero will improve further the SQ I would suggest that he offers such an upgrade for US customers in cooperation with Lukasz. Next time when my B7 will by modified I will ask if this mode can be done at factory. Like many others here I am not techie guy and would prefer to respect the warranty conditions . One of them is to not access and open the DAC without permission.

Balanced is available (and will cost more...doubled part count) and as I said its not a mod, its a rebuild. Ladder PCM is the default standard now for new builds.
Sure I spoke to Luk about the clock upgrade and in principle, he agrees it would not hurt...just as I said. better clocks, whats not to like? The issue that I kept repeating is that this mod has a cost and NOONE knows the upside it can bring, not least someone who has never heard a B7 or GG Dac. That is my first point. my second is that for amateur people like me, even replacing a stock Amanero was a fretful task I dont ever wish to repeat. I dont have fancy heat blower tools like I saw in that video posted on Vimeo, just basic solder tools.
So for Lampi to stock a $500 part or spend more on a bunch of new inventory for unproven gains , when there are log hanging software and FPGA control gains to be had would not be the wisest thing, but its not my call. I am just a curious bystander who chose to challenge extravagant claims here....especially when the claimant says things like NO bespoke firmware and I KNOW that NOT to be true.
Blizz is often over-reaching in his zeal. Its been months that he has been threatening to do his digital build to blow all else out of the water. I rather he start a thread about that and give us updates, instead of thread-crapping here on a product he never heard or used and his experience is limited to internet photos.

Perfect suggestion. He seems to think that I am opposed to his idea. I merely say its upside is unproven. Blizz will charge no less than $700 for the mod and likely over $1K. If he gets approval from Lampi to do it without avaiding warranty issues, it would be a potentially worthy endeavour and if its 5 mins as he says, very profitable for him. If its a worthy tweak, the word of mouth alone will make it popular and with the large US installed base, he has a sustainable business for the medium term.
None, I had a phone chat a few days ago. I do know that the digtal guy there has been designing PCBs every day since 1995 and has tons of experience. This experience has been apparently applied to the R2R ladder solution.
I must say that with certain exotic tubes that the Old PCM was lifted to be very close to the Ladder PCM (IMHO, just a few days back and forth testing, so not scientific or anything).
