I am a bedroom music producer and currently I'm looking for budget Dac Amp Stack or a Dac/Amp Combo . I currently using Motu M2(AI) along with Neumann NDH20 (main) and Beyerdynamic Dt880 pro (250 ohm) headphones and JBL LSR 305 studio monitors. As Motu sounds good I think they still lack power and I don't record instruments too much. I have came up with few options after reading reviews , like Topping E30/L30 or Schiit Magni/Modi stack. For combo, one is Topping dx3 pro and another is Aune Audio x1s pro. Are these options even good to make any difference to the gear i already have and if yes then are stacks better options then combo?
