So because of a power surge, my SMSL DA-9 crapped out on me, now im considering to change to either a AO200 MK2 or an A300, from what i gathered in this forum the A300 has a better package minus the balanced output option that i have never used, Both the AO200 and A300 have SW out which is nice. Im using a Klipsch R50M, have got a D50S Topping which receives input from my PC via USB. Where im from im not given the luxury to return a product after ive bought it unless its defective. A300 is about 50$ cheaper. Altho ive got budget for eitherone.
