I see that Eugenie’s installation did not create in people to think about it, I think it is unfortunate.

Here are some important points of Eugenie’s installation:

1)      Use instead of good drivers a large amount of mediocre drivers. By doing this the exertion of each individual driver is substantially minimized and within a very limited mechanical exertion even poor drivers sound as much better drivers.

2)      Complete randominisation of time aliment. Eugenie is not juts misaligned driver but has 200 sources of mis-aliment in very unsystematic pattern.  What Eugenie done was created a sort of Phases Brownian Motion where the multiple stochastic errors of phases kill in listening awareness an ability to discriminate the leading edge of waves. I do not feel that it is right way to go but it is one of the way to mask phase anomalies.

3)      Fine-tuning the Melody range. Eugenie’s use many drivers (20 random drivers!!!!) and have sufficient sensitivity in Melody Range (100-600Hz). This allows him very prissily to tune his playback to the response of his given room in the Melody Range that shall give a very “loaded” and meaningful “size” of the presentation.

4)      Use my method of Insertion Channels, what he combined the background sound of multiple drivers that set “pedal-point effectiveness” with tonal Insertion from special chosen drivers. I have to note that in Eugenie’s case his Insertion shall have much less negative impact. In my case I have lobbying from second HF source. In Eugenie’s case he has many-many phase-random HF sources, so I guess the lobbying will take less part in his case.

… I do not have time not buy feel free to continue the list for yourself.
