Nuansa A1 Batch 2 are on production now, for S.N #026-#050.
There is no any different on schematic or any function, but because every production are in small quantity so we call “Batch” every production.
When ready, A1 can be get at our Webstore. so there is no Pre Order for this batch and future batch.
Prototyping was done, and on mid of December we will produce a final unit of P1, only 4Pcs.
We hope that on next year we can produce more unit of Nuansa P1.
On final unit board, we was re route the path to get shortest path on digital section, and also isolation on analog section.
Also on final board, we use discrete active I/V with more complex 3rd LPF using OPA1622. Biased into Class A.
For direct driving headphone, we choose MUSES02 as default opamp.
Tube based Portable Headphone Amplifier!
Hmmmm.. wait, we mean NuTube, with discrete buffer to gain up the current without changing the sound signature of NuTube.
But are not promising this product will be produced for mass production, still lot of fun to research and developing with this technology now, don’t expect will be available in next year.
