Hi all. I recently purchased a set of Hifiman Ananda Nanos on an open box discount from Hifiman and need some Amp/DAC recommendations. I was looking at the Schiit Magni Unity for $189 as I have used the Schiit Hel in the past when I was just using my headphones for gaming. I recently decided to go a little deeper into the headphone game, which lead to my purchasing the Nanos after having the Hifiman HE400se as my first set of planar headphones. I very much enjoyed the sound of the HE400se, and when I found the Nanos discounted so nicely I decided to jump on them. I now need your assistance in finding a good amp/DAC combo to get the most out of the Nanos. I like a lot of different types of music from Classical to more modern stuff like Rush, Pink Floyd, Metallica, Chris Stapleton as examples. I will mostly be using them at my desktop in my home office and would like to keep the budget between $500 and $750 all-in for amp, DAC and cables. Thank you in advance for your kind assistance.
