Hypex Ncore

Regarding the first statement, is this confirmed or, as implied, unconfirmed speculation? As a Hypex OEM I'd expect you to have the definitive answer.



Btw there is something seriously wrong with your measurement of the "stock" NC500 LM4562 input buffer module. The LM4562 is much better than that and I can't believe Hypex would offer such an awful implementation. (Apologies for referencing a post from Nov, especially if things have been corrected in later posts.)



BTW can you repost your measurement of your discrete class A input buffer with the noise floor of the AP shown as well?


Yes as I said earlier it was picking up noise from the inputs. The only other test with the LM4562 was after some minor board mods. Noise floor was close to the NC1200 via the standard buffer. I already posted the measurements.
 
Thanks. And the first point?

It's been hard to get clarity as to what, if any, modifications to the standard NC1200 module have been deployed by OEMs. I believe Theta have not made any changes to the stock input buffer. Perhaps this is evident to someone more familiar with the modules from the high res pic I linked to above. The Theta Dreadnaught uses the same configuration as their Prometheus mono blocks except with respect to the toroidal transformer (and number of channels per chassis obviously).

I'm pretty sure the only ones that don't use the stock buffer are the Kaluga and the Bel Canto black.
 
Do you mean Bruno is making some Digital/Class D/nCore style DAC? If so do you have a link...interested to check it out

Pos and others have posted links to Bruno's project - but my point really wasn't about Bruno. He is just a pretty good example of a long line of very bright people who have furthered our knowledge about audio reproduction based on sound science and engineering - and openly shared their findings in peer-reviewed publications, so that people can learn from them - and find holes in their thinking. Science at work.

This should be seen in contrast to "designers" who tweak existing designs based on exotic component choices and "secret sauce" - especially those who respond to "how does this work?" with "no idea, but you can really hear the difference".

Not sure what a "nCore style" DAC would be. "Class D" only applies to amplifiers, and all DACs are partially digital.

One truly MASSIVE caveat to this: huge progress in science has been made based on observations which initially could not be explained but which were followed up on for the better.

So don't knock experimentation and constrain all perspectives into the box of present knowledge and blind AB testing else progress will grind to a halt.

You might also want to ease up on the audiophile bashing. You exhibit even just here in this thread a passion for audio which truly places you as an audiophile even if your gear may or may not be expensive.

Absolutely - all science begins with observations. But they need to be followed up with the next steps - independent confirmation, falsifiable theoretical models, and experiments to verify the models.

So don't knock experimentation and constrain all perspectives into the box of present knowledge and blind AB testing else progress will grind to a halt.
I am definitely not insisting on staying in the box of present knowledge - but I do believe that "extraordinary claims require extraordinary evidence".

As to blind ABX, it is a simple and effective tool to remove most of the influence of cognitive bias - and unless cognitive bias is catered for, it remains the most influential factor (by far) on listening results with high-quality audio equipment.

You might also want to ease up on the audiophile bashing. You exhibit even just here in this thread a passion for audio which truly places you as an audiophile even if your gear may or may not be expensive.
You are of course right about the passion (why else would I bother to write here), but I am being rather careful to make sure I don't claim that my personal preferences form any sort of general quality measure, and they are definitely not evidence of the superiority of one technology over another.
 
There's always that interim period between unexplainable observation and scientific explanation... It can last a very long time.

Sure

But you are very apt to bash 'audiophiles'. It is pervasive throughout this very long thread and, from my perspective at least, gets very tiring given your very prominent presence in this thread. I do sometimes wonder what percentage of posts you provide here... Just an observation. I value your objective posts. :)
 
BTW I am not sure why anyone would have difficulty removing the 7815 regs or the SOIC-8 LM4562. You do, however, need to sacrifice them. Just cut the pins with a pair of fine-nose cutters (or Dremel if you prefer) then remove the pins with a soldering iron and tweezers, tidying up with solder braid afterwards. Easy peasy.
