Although both are great amps, I’d go with the Aesthetix because their both their DAC and phono cards sonically punch way above their price points so it is a better buy.
Luxman 509z or Aesthetix Mimas
I am planning to purchase one of these. If I buy the Mimas it will include both optional DAC and Phono stage. The Luxman is $12,495, the Mimas is $11,500. My speakers are Harbeth 30.2 Anniversary edition. I listen to a wide range of music and enjoy vinyl, CD's and Streaming.
