Once i had the same question and someone actually measured the Ncore and came up with a similar, if slightly higher number. Whether one is bothered by half a megahertz feeding a 5m speaker cable is probably system specific.
I tend to be of the belief (based on some experiences of mine corroborated with those of others) that EMI/RFI is practically completely disregarded in audio. designing for compliance = knowledge, effort and $$$.

I happen to trust the guy in general, he's one of the few with common sense on the local audio forums.

Both me and my wife thought it was more muddy, less detail and "flat sound".
The singer did not come forward as it was earlier.

Again, not bad and i doesn´t know how much "burn in " time they need to perform as it´s best. I only run them for about 15 hours now. I will run them and do a real evaluate when they run for a few hundred hours.

Could be as easy as Class D is not "my cup of tea"
But the ncores were not the only change you did, right? You changed dac as well, I read on another forum.

Default Significant Audible difference?

I'm having a hard time grasping the affects of speaker wire gauge and length on sound quality with the NC400. My equipment is in the back of the room, with 30 feet of 10awg speaker wire to 250W 6 ohm speakers. Would I be loosing a significant amount of sound quality here? Would bi-wiring this wire make an audible difference?

There are weak points in the chain of audio equipment and in the overwhelming majority of all cases the speaker cable is not one of them, so probably not. Especially not since you have a decently sized cable already. Linkwitz covers the topic in some detail:

Hello,
I just came back from the High End in Munich where Bruno Putzeys presented two designs based on the Ncore. His Mola Mola line with Lansche Plasma speakers played in one room and the LS1 in another. Both sounded impressive, although I think the LS1 is the much better buy (the guy from Lansche told me that the whole system probably was about a quarter Million Euros, a small part only Bruno's components which are supposed to sell for 8000 Euro the preamp and 6000 for each mono amp). I had the chance to talk to Bruno which was very interesting. Bel Canto also demoed prototypes of their Black line which are based on Ncore 1200, but I didn't like the sound with the Joseph Pearl 3. If you know German you can read my impressions of both design of Bruno on my Blog flatworld.welt.de . You find Bruno in day 1 and 3.

30 feet shouldn't be much of a problem. In theory you will get a bit of cable resistance and capacitance, but unless you have an extremely current-hungry speaker, I can't see it making much difference,

I wouldn't think so. If there is any current-limiting caused by the cable, it will be on the woofer, and moving the much smaller currents going to the mid/tweeter off the cable won't make a real difference.

It depends on the cable -and the rest of the system of course. In some systems cables matter a lot. But in such cases the sheer gauge usually isn't the primary concern.

And do you think the nC400 is one of them?
