Was tipped off about a new DAP that looks interesting. I have taken a punt and ordered on recommendation. http://www.dethonray.com/ Made with the precision machined aviation aluminum-alloy which can enhance shields and eliminate interferences from external signals. The custom-built battery sets can avoid the boost circuit noises and improve the efficiency of electricity supply, ensuring the a detail and transparency beyond “CD-like” audio quality. ‘Real Live Sound’ DAC AK4490EQ, dual OPA1611 low pass filter, AD8397 circuit design making great performance for both earphone(16Ω) and headphone(300Ω). The customized Linux OS, optimized decode engine and independently developed super-light GUI system provides excellent user experience and is able to handle 100,000 songs in 6 minutes which stored in the Micro SD card. The high quality of the power supply and well-designed OCL single end audio circuit make no equal in sound quality. Cost circa $600. Can any of the aficionados comment based on the specs.
