My experience with Aesthetix was in the form of the Janus. I found that the Janus really needed and merited better coupling capacitors, which is largely what you get if you opt for the Signature version of either the Janus or the Rhea. I highly recommend that upgrade to anyone trying to optimize the performance or SQ of the Rhea. With really good capacitors, I would bet the Rhea might compete with the Allnics.
