I looked at Aesthetix years ago when I bought my LS26 and as much as I liked the sound, I decided on ARC and recently I bought an REF5se and all I can say (as I listen to Roxy Music) , I can't imagine you being disappointed.
Aesthetix vs ARC
I have a general question for those familiar with the two companies listed above. I'm currently using an Aesthetix Calypso which I consider a top tier preamp. Recently I've been thinking about trying an ARC reference preamp. To be more specific a reference 5 or 5se. I expect the ARC 5SE to rate higher but i'm not sure how their sound signature compares to the Calypso. Please don't ask what is that I don't like about the Calypso or how much do I have to spend, etc. I just want to know the sonic signature of the Ref 5se compared to the Calypso. I do change equipment from time to time like everyone else.
