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

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.

Oh Brother!!
Off topic rants cause me to glaze over.
Then I skip them and look for real information.
Thank you Roger, and all who have shared pertinent info.

The only one I see ranting here is you. I suppose every organ grinder has to have a monkey.

"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?"

obviously measurements have been made of atomic particles for what, a centrury? Of the diameter of a neutron, the mass of an electron, the wavelength of a photon and so forth. They even determined the mass of a photon. Uh, it’s zero. Like your amp’s distortion. So Measurement at the nano scale is nothing new. For audio, one can measure the sensitivity of extremely sensitive preamps, you know, the ones with noise figures 130 dB down. And THD 0.0001%. Those are mighty small numbers, no? The size of a pinpoint of data on the CD, any idea how small that is, or of the space between the data tracks? Or of the diameter of the laser beam? Next thing you know you'll be calling the data quantum.

"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."

Yes, jitter is a term used in the digital world. Maybe you can use the analogy of the electron microscope and trying to take a clear photo of the subject under view. Without vibration isolation you would only see a blur. And extending this analogy (get it, analogy?) a little further, it was actually a microscope vibration isolation stand that was pressed into service as the first highly touted audiophile vibration isolation stand. The Vibraplane. Perhaps you’ve heard of it. In any case, I’m afraid vibration isolation has been around with us in this hobby for at least twenty years. Maybe your amp would run more perfectly if you isolated it or is it immune?
