First show us some measurements before and after the cap switch. Then prove any objective improvements are actually audible.
Instead of arguing the point with me, as I really don't matter, why don't you ask Bruno his opinion. He is usually very open and willing to discuss his work and these types of topics. While you are at it, you can ask him what he thinks of these cap mods.

No I'm not saying any thing about capacitors creating noise/distortion. That doesn't make sense. The capacitors are part of a filter. I am saying due to how-no-one-knows-low-noise-effects any improvement in the filter is positive to our ears. If what was being filtered was a different type, we perhaps wouldn't notice the change.I'd love to hear from Bruno so long as he tries the mod.
Or if the mod sounds better to your ears, who cares what anyone else thinks?So are we back ro the 70's again where low distortion only matters? I remember being young and naive back then and falling for this hype.Never again.
You've missed the entire point of the discussion.
No one said the affects of inaudible things exerted with audible ones are inaudible. We don't understand it, but it seems to happen.Also our measurement for audible is based on detection, but given the massive amount of information (terabytes) we might hear and not know it. It's possible maybe mood changes could be detected or something, even when the person can't tell you they hear a noise.
Which is the more important criteria to base a decision to buy an amp on? How the amp measures or how the amp sounds?While the Ncore 400 was designed to be a "neutral" sounding amplifier, neutrality is only a good starting point. Once this goal has been achieved additional performance parameters need to addressed, such as the preservation of dynamic contrast, the height, width and depth of the sound-stage, depth layering within the sound-stage, three dimensionality of the sound-stage,(ie does the amplifier image in front of the plane of the speakers as well behind the speakers). The foregoing was obviously an incomplete list of subjective amplifier characteristics. Any or all of the above subjective parameters can be affected by the choice of passive parts as well as the active circuit design. To debate the audibility of a change in the sound of the amplifier based whether there was a change in a measurement is rather pointless. Especially considering that the amplifier was primarily designed to meet a subjective goal based on how it sounded to the designer..The hobby is listening to music, an activity based on subjective experience, not reading objective specifications. If one argues that a certain level of measured distortion THD, IM or what ever is well below the threshold of audibility and therefore could not impact what is heard, then you are very close to arguing that all amplifiers measuring below .05%THD will sound the same. Shades of StereoReview and Julian Hirsch.Scotty
Not really. Months ago I asked you how your low distortion figures translate into the quality of sound stage and transparency. I have heard other neutral amps that has more of those features in my system. But maybe the right mod can improve that on the Ncores. Isn't that is what this is all about?
