Actually, I just read about the H-CAT approach.
Seems like it requires careful "tuning" to provide the advertised benefit and that some have achieved "it" and some achieved something perhaps less desirable otherwise.
Definitely a different approach than Carver sonic holography, which the site correctly alludes to.
Having heard that the Carver holography does in fact work, I'll keep an open mind regarding this approach. Sounds like a different approach to lowering amp distortion than typical negative feedback approach as I understand it.
The site left the impression that earlier versions did not provide adjustment of the correction which is absolutely needed otherwise the chance of the gadget working was low. Assuming true, it was not very smart of the vendor to sell a gadget to audiphiles as such (missing a primary feature needed to work in most cases).
The Carver approach was technically not that complicated, yet effective. This approach seems much more complex and harder to get right, assuming it does in fact work. I suppose the only way to know would be to try it.
Does the vendor offer any kind of money back guarantee? I would think that might help entice those interested in taking the plunge.
Were I to go to a different SS pre today in search of better sound (rather than tube), I would strongly consider Classe based on what I have actually auditioned and liked.
