Gustard A20H DAC/Amp

Hi all. I wS thinking to upgrade my current amp + dac to an amp dac combo and was wondering if Gustard a20h would be any good. Does it have any quirks or features that I should be aware. I am trying to drive a pair of Focal closeback. I would also like to use the outs for a speaker amp. Please advise for any alternative as well. Price range of $500 to 600 ish. I currently have a topping 50s for my headphone amp. Thank you.
