"You hear what you believe". Have you ever heard of perceptual bias?

Naah, you will just be accused of subjectivism and lack of scientific rigour...

yeah not that I disagree in general, but I do kinda object to this video being presented as a test that they actually did think they all tasted different. to me, particularly the restaurant section, its clear to me that they are making **** up to cover the fact that they couldnt taste any difference, but they didnt want to come across as unsophisticated, so they spouted nonsense. of course this is a factor in audio too, but it kinda dominates the result of the test IMO.

I did forget how awesome they are though HA, just watched the fengshui one too

back to square one!

Is this ment to be a joke or sarcasm? Forgot your smilies? Do You even know what is in his rig? These kind of comments I would expect from a beginner trying to defend his own choices while buying one's first rig, blind. As I have read Your posts in the past, this shouldn't be the case though.

I've been known to forget smilies now and then.

it was a joke aimed at the fact that the objectivist vs subjectivist debate is circular almost by definition. each camp can always bring an argument that "resets" the discussion.

Agree.

of course this is a factor in audio too

A pretty significant one, I would say...

I wish they had done one on audiophiles...

Why not the two ?
I do not understand this debate with the gain modification of the Ncore.
What is the noise figure output of it in the both figures ? Do unmodified Ncore noisy enough to be heard on high efficiency speakers ? If not, there is no interest to change its gain, and a resistive attenuator right at the input will do the job perfect, and can provide a better isolation of RFI/EMI in the input line.
With the huge open loop gain of the Ncore, i doubt any change in its feedback loop can bring any practical change in the damping factor: il will be limited mainly by the loudspeakers wires.

That is what some users have reported.

Perfect? It will spoil teh impedance matching between source and amp, and probably introduce some noise.

and can provide a better isolation of RFI/EMI in the input line.

How do resistors isolate RFI/EMI?

Probably not a big change in damping factor, but a small improvement in distortion and signal-to-noise...

@mr_push_pull: understood. As a moderator in our local hifi forum I have become very allergic to those kind of comments. Which fortunately was not the case here and I (sort of) overreacted.

If it were, it is BCP to mark it as one by adding smiley or to. Otherwise it can and will be interpreted as open assault and/or "reset" comment as mr_push_pull said.

For the rest of You guys, sorry for the offtopic.

Ok. Then, for them, and them only, it will bring an improvement. While, i wonder how an amp with 124dB of signal-noise ratio can be heard on a 100dB/w speaker: If will bring ~127db spl full power, so the noise will be 3db !!!! (remember a silent room noise is 30dBspl.

I doubt that, at this line level, the contribution of noise by a metal film low impedance attenuator brige is something to speak about.
Resistances does not islolate RFI, but we are talking of an 'attenuator', right ? And in the other sens, it brings an added isolation for the feedback loop of the previous preamp, if any.
