As we all know E01 has a Sabre DAC, the ESS9038 pro while the T01 is powered by Dual PCM1792A DAC's.
The E01 is able to decode PCM up to 32-bit/384kHz while T01 is able to decode up to PCM 24-bit/192kHz.
The E01 has a single-ended 3.5mm output while the T01 offers a single-ended 3.5mm and one balanced 4.4mm output ports.
The E01 gives a power output of 150mW at 32ohms load while the T01 has a power output of 245mW at 32 ohms load via the 3.5mm single-ended output.
The E01 has a dynamic range of 120 dB while the T01 has a dynamic range of 116dB, the sound has a better and clearer background in E01 motherboard.
The sound output through E01 is kind of similar to that of T01, but if you notice closely it is crispier and the stage has a wider feeling, overall we really liked the E01 as compared to the other two audio motherboards by Cayin.
