I know nothing about Moon.. I have been using LUMIN (D1, D2, and T2) for over 8 years. Great warranty, great build quality - constant software updates via the internet. The only amazing thing I am learning is as I have improved my signal quality coming into my two stereo systems - quality of sound ( lower noise floor, better imaging, larger stage, more instrument clarity, tighter base) keeps going up.
i just moved from Spectrum copper wire internet feed, to fiber optic feed, and added a SmoothLanNetwork Filter. OMG
My streaming has continued to improve!
Happy listening
