Please help me chose a tube preamp


I have an opportunity to buy an  Aesthetix Calypso Line Stage amp, I need to know what you all think of it, please.
I do not want to buy something based on reviews of high end audio publications, for I do not want to make the same mistake when I bought Totem model one, Triangle Titus, Audio Research LS3B. All  of these  were a major disappointment for me. 

There is a VTL TL 2.5 available as well, for less then half the price tag of Aesthetix.
I have a Levinson 431 power amp that  will be paired with the selected preamp.

Anyone have any experiences with this Aesthetix and VTL?

Cheers

As mentioned by some posters my experience the Calypso and Rhea was also disappointing. Reliability issues and the sound didn't stand up with audio press enlightning comments
+ 1 on Hiphile's recommendation.  I was the third proud owner of the excellent preamp.  His newest version is three generations improved from mine.  Google Don Sachs preamp for many excellent reviews of the preamp.  It is truly outstanding preamp for around $2K.  I'd bet it would be very comparable to the Cary Audio SPL 05 for about 25% of the cost.  Both preamps employ venerable 6SN7 tubes, which is where the magic lies.  
I bought the Calypso about five years ago and have been very happy with it's performance. I'm currently having it upgraded to the "Signature" model. I like its versatility and the sound is fantastic. Like most tube preamps, it has a little tube rush, but am expecting that to be gone, upon its return. The only downside is the cheap looking remote. U would expect a company with a name of Aesthetix, to be more concerned about the aesthetics.
