Well the guys at Quickcircuits turned the Rev C Nord Input Buffer Board Around in 5 days and done a really good job. So here they are complete with Sonic Imagry 994 OP Amps and our new Sparkos Voltage regulators, They are the best sounding combination so far and has really improved Soundstage.
An externally hosted image should be here but it was not working when we last tested it.

Where are the speakers outputs?
Behind the opamp?
 
Mundorf - Inner Excellence

Due to the complec bifilar structure from 1Ω with two wires being wound around the high-temperature-resistant cement element simultaneously the inductance is always below 75µH...

we apply a special copper-nickel alloy as conducting material featuring a positive and extremely low temperature coefficient of only 50ppm/°C...
 
Finally, the LPF at 18 kHz and Q=0.7 for a less fatiguing listening (and to emmulate the R2R DAC response, maybe).

From me, the ideal curve is: flat response with a slight negative slope, like the Tony Gee loudspeakers kit:

Humble Homemade Hifi - Plutone

And now, the NC500 thread can continue, please.

"Trust your senses" was a great mantra up until about 1620 or so. I guess that didn't include the sense of smell.

When you eat do you taste the food at all? Or do you just run a tube down your throat and pump in super food concentrates? Without knowing the complete history of the food you eat all the back to the creation of the source, if you enjoy what you taste, it will be wrong, and you should be utterly ashamed.

When you cook, do you rely on constantly tasting the food to know when it is done, or do you resort to a clock, a thermometer and calibrated oven settings? Do you add ingredients purely on taste, or do you occasionally resort to measuring quantities?

Can we come up with even more far-fetched analogies? :)

Cooking and eating are 2 different things. In the case of the Ncore amp modules, Bruno was the cook. So as end users to decide if we like them we must use one of our 5 senses to determine this. Hearing. Just like when you go to a restaurant and order a meal. We use another one of our 5 senses to determine if the cook did a good job. Taste. As far as I'm concerned, our 5 senses are still useful today for most humans.

That is true if you see yourself purely as an end user - but this is DIY audio.

Of course they are extremely useful - just not sufficient as our only source of knowledge. If we purely believed in our senses, we would still believe the world to be flat (and the centre of the universe).

But yes, this is an endless off-topic discussion...

So what have you done to your NC 400's to tailor the sound to your liking? And yes thinking that today's measurement gear has advanced to the highest level possible is a pretty flat earther way of thinking as well. If you don't understand why something sounds different, it doesn't mean it doesn't sound different. And if it sounds different and you don't know why, it doesn't automatically mean it's imagined. Especially when 100's hear the same differences and can describe them all alike. Colin's new buffer boards potentially measure better than the NC400's now. But if you seen all the measurement data, could you describe the tonal differences between them?

DSP and loudspeaker.

Indeed it would, if anybody would make that claim. I haven't seen anybody do that.

If 100's *independently* without affecting each other reach the same conclusion, then yes. I haven't seen that either. 3 or 4 doesn't 100 make... And remember confirmation bias is a strong thing - if somebody states there is a difference, a lot of people will hear a difference, independent of whether there actually is one or not.

If all that matters is DSP and loudspeaker, then you shouldn't need amps that good. So far everyone who's heard the Sparko opamp say it has more of a mellow character. And it's not because they heard others say it. It's because it does. But good luck picking up on why reading the measurement plots.

So if you heard the Nords with the new SIL994 based buffers and liked them better than your NC400's, would you admit it without seeing the measurement data? Or would you be to afraid to give your opinion?
