I want to eventually get a Woo Audio amp to use with my AKGs, and maybe some orthodynamics in the future, and I was looking at getting the Woo Audio WA6, and source my own RCA cables and DAC separately (something like the 100 dollar Schiit Audio Modi). So the total would be about 850 dollars. But for 1000 dollars, I could get another OTC amp instead, the WA7 fireflies, which has an onboard DAC and amp all in one package. Which would I be better off spending my money on? The WA6 and source my own DAC, or get the all-in-one WA7?
