By 'high-maintenance', you mean finding an amp that will have enough current and wattage? Yes, there is that.
@larsman Exactly correct. You need a bonafide 2-channel amp that can drive home speakers to drive the Susvaras, and that’s an expensive and tough ask in a HeadFi setup and brings things to a much higher level in expense whereas I can easily power the HE1000SEs with my LTA or even my Singxer Class-A solid state amp.
@mahgister I really wish I could help answer your excellent question, but alas I’m going through a divorce and haven’t had the chance yet to hear my MZ2 with my Arya Stealths yet, which gives me huge amount of frustration. The amp I’ve been using up to this point is the fully-balanced, Class-A Singxer SA-6 that, frankly, sounds pretty damn good through excellent balanced silver LavriCable headphone cables. I’m thinking I can get my MZ2 up and running within the next month and will definitely share my impressions, but I’m highly impressed with the Singxer SA-6 with my Arya Stealths FWIW.
