I want to get a topping d1 mark 2 , for a general purpose dac/amp, since my fiio e17 is pretty much tied to my ipod touch now , forming my main portable rig, but I want something new too hook up to my laptop , and say my note 2 , or alot of dap I will get in this year, I want for this one to have one of those volume knob for easy adjustment , I think I will have around 200$ budget when I am getting it
I was thinking of topping d1 mark 2, will this be an improvement? What are my choices with that much budget?
