[svrle85]

topping a70 pro + d70 pro vs fiio k9 akm for use with desktop pc for gaming and movies with jbl 4305p, I listen music rarely have big flac library. Have seinheiser 58xx from massdrop headphones.
topping have advantage because of white)silver option and I have speakers in white, same as mouse keyboard and desktop case.
I am new in hi fi world understand its mostly subjective about listening.

The 4305p have digital inputs and may even digitize the analog inputs, so those don't need a DAC. Just feed them using an optical connection or USB from your PC. For your HD58x, the A70/D70 stack seems a little overkill. Maybe look into the Topping DX5 II combo unit, which is also available in silver. Sound wise, there should be no audible difference between any of the options.
