The previous new version has been updated to the 2020 version with better AP testing metrics, including a lower signal-to-noise ratio and lower harmonic distortion. The sound quality is purer, the level of detail is improved, and the air is improved.   ES9038PRO is 8 cores, 2 channels with 16 cores decoding output in parallel. It is normal that the temperature of the decoder is a little higher than that of the general 2 cores. Both are very safe working temperature range. This product uses the imported TALEMA fully sealed transformer, which is full of energy, low interference and excellent strength. At the same time, the input is equipped with EMI to make the level performance more ideal and clean. Adopt the advanced version of BT chip 5.0, fast transmission speed, stable signal, lower power consumption. This card only supports I2S output (DSD format is also acceptable) Technical indicators: DSD512, DXD 384K. A Support DSD Native (source)
