Just stumbled arcross this: http://www.wolfsonmicro.com/documents/uploads/data_sheets/en/WM8804.pdf Anybody knows if the spdif is directly feed into the sabre or by some part like this spdif receiver with pass-through-option? Or is this part of light-harmonics re-clock patent? And there...- LucasB

They always intended to sell it afterwards on a regular way. You find information on their website. Mu-metal even over the clock-supply is really good! Anybody knows if the case ground-lift-switch from the ideas back in 2013 made it to the model?- LucasB

Yeah I know. But I looked it up on wikipedia and even if both are 75OHM in the spdif-specs, the bnc-style has a little bit different voltage levels. I just thought since we all have 2 rca, I would be up for switching one. Buying another adapter is possible but just thinking why… I do not know...- LucasB

Anybody knows if of all that spdif as well a bnc-spdif will be onboard? I have one specific item in mind for connecting to the pulse that only features bnc-spdif.- LucasB

So at least the generation of the signal is immune to emi - guess a bigger mu-metal-housing would cost maybe too much? At some point it is maybe just good enough - if the signal is strong and the path is short from clock to dac that is maybe sufficient.- LucasB

Hope the shield is not only over the clocks, but also over the part the clock is going to: the dac IC, so clock and dac are under one roof. A 2 Layer shielding will be really good. The outer case as general shield and the mu-metal for the high-precision parts. Wow!- LucasB

Although I would agree with amham, that with the wave online, it is hard to imagine the pulse gets all attention. But I think and hope it is only the communication that moved on to the next project while the design&engineering stays with pulse. At least that is how I understood Mr Larry Ho from...- LucasB

I can see your point, but In my opinion you are a bit fast-judging. The variations have been added because of demand not because of try and error. I dealt a little bit with product "families" - every company has it if you look around: From small to big car. From heavy to light bicycle. From...- LucasB

Interesting, very good to know all this. I remember switching gear for head-phone out from laptop to an old Yamaha amp and still the old and used amp's out was better then modern laptop's one. Will take a look inside and maybe I will discover it has one of the better implementations! Only it is...- LucasB

Oh! Thanks! Didn´t check where implemented. But good raising the question and thank you Larry Ho, now we even know more. I am not so much into audio circuits, but nice to learn something again!- LucasB

According to this test http://www.head-fi.org/t/528380/electrolytic-capacitors-used-in-audio-dc-blocking-comparison-tread elna silmic seem to be one of the best to get, really good! Just depending if "warmer" (old) or more "neutral" (new) Wow!- LucasB

Had no doubt about the performance, not a second - that´s why I backed "pulse" (though not yet sure if I have to nickname mine) (Just wanted to say, if I will ever have a possibility to do a test for some sort of self-designed product, I would politely put "competitor 1"… enough about my...- LucasB

I do not know what some of this thread-followers think, but posting measurement results of others I personally think is somehow difficult.- LucasB

For me that sounds almost too fast, let´s see. If they do not want to use the pcb both-sides (I guess because of solid ground planes and ease of manufacturing) and if they do not want to make the enclosure bigger, they can maybe stack the pcb´s. A good consumer-product I had in my hands and saw...- LucasB

Hey, I read on the forum that aes/ebu will be on board. Looked it up on wikipedia: and it says usually aes/ebu uses 110Ohm with XLR-Connector on balanced cables. 75Ohm and BNC and twisted pair cables. Will the xlr be matched to those standards or how will it be done? I saw there are quite a...- LucasB
