The E70 Velvet expands on its predecessors' strengths while retaining all its positive qualities to raise the bar for audio performance. The primary update with the new E70 Velvet over the OG E70 is in the DAC chipset architecture. From ESS’s flagship ES9028PRO on the E70 OG model, Topping has jumped back into the world of rich AKM DACs. While the OG model brought you crisp, detailed sound with its ES9028PRO DAC arrangement, the new E70 Velvet brings us the goodness of AKM’s flagship AK4499EX+AK4191EQ DAC Chipset. AK4499EX chip brings the highly-acclaimed Velvet Sound Verita technology that promises rich and smooth sound with the E70 Velvet. Also, with COAX/OPT-IN, the OG E70 supported PCM up to 44.1kHz-192kHz/16bit-24bit and DSD(DoP) DSD64, while the E70 Velvet only supports PCM PCM up to 44.1kHz-192kHz/16bit-24bit.
