"The Allo DigiOne combined with the Multibit DAC sounds fantastic..."
"DigiOne pulls five star sound quality from RPI..."
"It is very natural sounding, there is zero harshness..."
Our regular DigiOne has no equal.
In our quest for digital perfection we asked how we can improve the design and give you the ultimate DigiOne.
First, we decided to use more board space (we are using 2 boards), the PCB area increased 220%. First board is the “dirty side” and top board has the “clean side”. With the extra space, we used the best decoupling capacitors (film) on everything that’s important (clocks, buffers, flip flops). Also, with this extra space we added a supercap on the “clean side” so most of the electrons come from this onboard “buffer” (there is so much power onboard that DigiOne Sig can run a few seconds without any power attached to the clean side).
We also decided to use 2 power supplies. The “dirty power” needs 5V /2-3A (RPI power). The “clean side” needs about 100mA and accepts from 5V to 6V. You can use anything on it, linear power supply or pure batteries power.
Thirdly, we changed the clocks to the latest from NDK (ultralow jitter SDA) that have lower phase noise than the previous generation.
* Please note that all acrylic cases we ship, have a protective film (which looks like brown paper). You will need to peel this film off, in order to reveal the case. This is to prevent scratching and fingerprints during shipping.
