Aesthetic preamp


I am looking into changing my preamp from AR SP6 B to Aesthetic Calypso . Love the AR but I want balanced inputs/ outs.
Any opinions on the Calypso? 
Thanks

I have an Aesthetix Calypso paired with an Atlas power amp. Great combination. No idea how it will match with your current power amp.

It may be a better match than the AR 6b.
I've owned a Calypso and currently own the Calypso Signature.  Both units have provided many years of trouble free musical bliss.  
I agree with the Aesthetix praise. I upgraded my Io to partial Eclipse version. Bliss indeed.
I have the Callisto partial eclipse and like it better than the Janus or Calypso.  I am considering moving to the IO for phono, but I don't have the room for a four chassis solution for pre.  I already have the mono atlases so I am lean on space.  I would suggest a Janus sig for bang to bucks.  Enjoy the music!
@elf1: I have the Calypso Signature and find it to be everything I need as far as the connectors go, (almost) as well as the sound.  It, as others do, it has a muting circuit, which puts it into standby mode as soon as it’s powered up.  The only thing it doesn’t have that I wish it did is xlr outputs for the tape monitor.  I’m using all balanced cables, except for the tape monitor, which I use for my subs. It’s very clean, dynamic with plenty of gain steps.  The balance control is very handy, as there are both LP’s and cds that I will occainsionally need to adjust slightly.  For a company called Aesthethix, the remote is a little cheesy looking.  As with any tube amp, the end sound, will be greatly influenced by the tubes you use.  It also has an illumination control, for dimming, or turning off the led read outs.  The top opens up for tube rolling, by simply lifting it up.  No tools required.  I’m pushing a couple of Krell monoblocks and the combination gives me all the slam I couled ever want.  Great midrange and highs too.  I’m very happy with mine.
