acoustic system resonators

Onhwy61, where did he say anything about RFI absorption?

Why should he provide you with evidence? Why don't you listen to some or attend a demonstration?

You are probably right that most audiophiles would not consider all of the electronic circuitry in the Lexicon PCM91, but why should this logic apply to the Resonators? Because you say they do the same thing?

I read the phrase "absorb certain emi and rfi" as Audiooracle saying something about RFI absorption.

Tbg, I suspect the resonators do exactly what Audiooracle and others describe, I'm just arguing that it doesn't contribute to greater sound reproduction accuracy. I went to the Acoustic Systems website and read their description of their product. They state that it vibrates and adds overtones. These overtones are not in the music signal. Therefore I reason that their product is adding distortion and by definition not a high fidelity product. The effect may be very pleasant sounding, but it's not accurately reproducing the music signal.

I could be wrong. Maybe it's not akin to a Lexicon reverb, but more like the Aphex Aural Exciter. Go easy on the big bottom knob!

Sorry, I had not recalled that.

I grant that explanations of how it functions cast suspicion.

Here is the test data that you request:

The fact is that resonators work and two different sets of reviewers from two different magazines both hear and swear by them.

Why don't you non believers try them and see for yourself you might be thrilled with them.

Most electronic processing is not built to the same standards as the high end components that most of us are using.

I came across what may be a reasonable explanation for the possible effect of Acoustic System Resonators - it seems that this kind of devive may produce multiple harmonic overtones at the same time. Similar to what happens if a tube amp is overdriven but different becuase it does not necessarily add richness to a the note played...in fact it is multiphonic and polyphonic (adds many notes - quite different from a bell).

Of course, this is passive - so it may only respond to excitation by the sound waves in the room, however, given our huge hearing sensitivity (0 to 120 db spl) and the fact that a subtle sound from a ringing cup may be audible between loud notes when music is briefly quiet then it may add something.

What will it add....if you read my link above then you will get an idea...this type of thing is used in meditations by monks...so atmospheric kind of shimmering quality is to be expected.

Is this audio reproduction - no, not in my mind but it may have an audible effect and that effect may be pleasing to some people. YMMV
