A stands for AKM, T stands for Texas Instruments and E stands for ESS Sabre. These are the companies that make the delta-sigma chips inside the amp cards. This gives Cayin plenty of scope to not only release more TI or AKM cards with the number series but to also go with different companies and change the letter series.
The design architecture of Cayin E01 Motherboard
1. The DAC adopts ES9038PRO, in which the eight-channel DAC is output in differential current mode. The four channels are connected in parallel to form a sound channel, and then connected to IV conversion.
2. The circuit board of the amplifier is built with discrete components, which is composed of special low noise audio and crystal transistor. It has a powerful current output capacity and load control ability.
3. The power amplifier circuit has dual working modes of A and AB, which can be switched instantly through the UI.This is the first design for a portable player.
Just an important note here that changing to the E01 does affect the N6ii battery life performance significantly. From around 13-14 hours (balanced and balanced) it goes way down to 7.5 hours under Class A, 9.5hours under Class AB.
Cayin E01 delivers gorgeous highs without harsh, giving you a natural, crystal-clear sound. The virtual stage is more than average, it is quite harmoniously lined up both in width and in depth. Sound sources are precisely placed in space.
