What would be a good portable Dac/Amp to use with my HD6xx and Sony Xperia 1 V cell phone?
I am new to this hobby. I purchased a HD6XX and plan to use it with my Sony Xperia 1 V cell phone, that has a 3.5mm jack. I was wondering if I needed a portable dac/amp or just a portable amp and if so what would one recommend? Any assistance one could provide, would be greatly appreciated. Kind regards, Haz

Two sets of linear power supplies Most competing products use 1x15V or etc adapter to the amplifier, this 1x15V will be convert inside the amplifier and cause noise and interference. But we use linear power adapter to provide 2x15V and 1x8V to A30, which help A30 avoid these problem. 2x15V used for high fidelity headphone amplifier circuit. 1x8V used for MCU, LED and relay. Less noise, less interference. Source: http://www.tpdz.net/en/products/a30/index.htm
Output impedance: 10 Ω (6.35 mm output) 30 Ω (3.5 mm output) <------ Why???? Source: https://www.soundphilereview.com/reviews/topping-a30-review-754/
