Has anyone heard the new North American products preamp and amp?

pretty sure that entire paragraph is another one of those false arguments, you know....a Strawman argument.  What is illogical about it?  Well, for starters, we have the capability to measure things that are nano scale.  Actually the way CD players work is based on the geometry calculation of how the quantum mechanical laser reads the nanoscale data on the disc.  Now, just because the data is nano scale and the laser beam is nano scale doesn't mean that the laser reading operation is quantum mechanical.  It's not.  The only thing quantum mechanical about the entire process is the CD laser! like all lasers, you know being a quantum well. Obviously we have the capability to measure the nano scale data on the CD otherwise the Reed Solomon error detection correction wouldn't work. Another perhaps even more dramatic example of the the ability to measure nano scale phenomenon or waves or matter is the recent announcement that the LIGO project finally observed gravity waves. This announcement was actually made only a couple of weeks ago. Now, why is this relevant?  Because the amplitude of the gravity waves that LIGO detected was on the order of the diameter of a neutron.  That's what we call nano scale. So, with this measurement by LIGO we don't have to be theorizing or stumbling around wondering whether gravity waves exist or whether black holes exist or, by extension, whether the Big Bang is real.

As we saw a couple weeks ago the LIGO project finally observed gravity waves and they had to use isolation to do it. Isolation of the optics.  

Gee - you mean somebody had a theory about something they thought existed even though they had no way to measure it? That's crazy talk.

It apparently took a bunch of scientists with a desire to get the answers quite a while to detect it - and had to use extreme methods to expose it.

So, you really probably should delete the expression, isolation can never be achieved, from your repertoire.

I agree, we can't say "never" anymore. I am in no way claiming the perfect amplifying method but I believe I am on the right path to make it happen.

The recording industry still needs to clean up the analog stages.

Ok - so if we already have the capability to measure things that are nano scale and you are assuming it can be applied to sound reproduction - why haven't we done it already? Has the audio industry been wasting its time when all they had to do is use the magic tools we already have?

Because we are talking apples and oranges.  Reed Solomon does absolutely nothing in the analog world. It only deals with on/off. I was afraid to use the term "jitter" when describing my work but I thought it might trigger some kinship to the concept of tiny amounts of interference or disturbance. This is why I prefaced it with the term "analog". I realize it is probably an oxymoron since jitter is deviation or displacement of a pulse in a digital signal. It may only have added some confusion to the correction process I use which is 100% analog and also lives in the nano scale.

Hey Roger,

I am very fascinated by the discussion so far and is in agreement with the consensus that proof of the claim is in the listening. Is it fair to speculate that this technology could soon be available as a separate device to be placed before the speaker providing much of the same effect?

hew,

You are right the proof is in the pudding. As far as a separate device - as you know a chain is only as strong as its weakest link. I have had great success at the power amp end of the chain mostly because the power amp has a tricky task to perform correctly. That is driving the final transducer that converts the electrical language into mechanical language that ultimately allows the sonic continuum to make its way to your ear-brain system. However, every part of the chain should be of the same caliber.

The Wavefront Timing Control I developed on earlier models of the preamp was a way to manually decode or filter a fixed disturbance in the chain. It required making a separate adjustment every time you switched sources or even between different recording labels. The current auto-focus system is much more sophisticated in that it can detect the velocity that comes embedded within the audio signal. For this reason I use auto-focus in the preamp as well. The DAC and the phono stage also has auto-focus because it handles issues that pertain to the specific stage in question. It cannot guarantee fixing anything upstream. (A bad front end will still sound bad).

There are many recording studios waiting now for this process to be available as a mic preamp which is already under way. I hope to have recordings done this way later this year.
