Luxman 509z or Aesthetix Mimas

I’ve heard the 30.2 with either an Audio Note Soro or Oto integrated amp and with the Synthesis A40 and A100 integrated tube amp.  All sounded good.  These two Synthesis amps are among my favorite integrated amps—warm, bold, punchy, and a sense of weight and authority, particularly at modest listening levels, that one does not commonly find in most amplifiers.

Buy the Luxman because it sounds fantastic and because you WANT the Luxman to win this race. There is no wrong move here, just pull the cord. I listen to the 509Z daily and it gets better every day

On a purely practical note, the Luxman will hold its value better and likely sound just as good. 

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.
