Post Subject: AudioPax New A5 GenerationPosted by Amir on: 5/26/2019
AudioPax now is directed by Silvio , a good guy who continue producing Audiopax in Brazil.
Silvio now is finishing the 5th Generation of these Classic Models.
I follow Audio Note , Border Patrol and AudioPax because they are different to other manufactures.
I know this forum is not about product specs but i would like romy let me to publish it.
AudioPax New Model 5 & Moled 88
Both the Model 5 as the Model 88 work without any feedback on their audio circuits, something that is really much harder to implement with low noise and thermal stability but that, at the end, allow us to achieve a unmatched performance. But I would like to remember that what we call “audio circuit” is only a kind of “control” path for what, at the end, really “moves" our speakers drivers – the power supply current. So, it’s fundamental that this path also have all the care we normally take on the audio circuit regarding instantaneous and dynamic performance. In our case, all our power supplies has no regulation at all, something that could be considered as a kind of feedback (a very strong one, by the way). This is a really rare concept (I use the word "rare” but I don’t know any other company that uses it), probably because most of our “formal” Engineer education is directed to think about tensions (not currents – although everything are, at the end, moved by it) and looks as pretty clever to keep a fixed tension on the power supplies at any cost (even the audio performance, in our thoughts!). Besides it we work with a minimum of capacitance on our power supplies (1000 times less when compared with some manufacturers), another concept that makes our power supplies much faster than the usual ones.
On the fifth generation of our products we have completely redesigned power supplies that now are even better, faster and with lower noise figures than the original ones. I believe this was our biggest change ever – the result of these new circuits are simple incredible and will be presented for the first time on the next show.
