Herron 1A,, Herron 2A, Modwright LS100 or Aesthetix Calypso?


I have narrowed down my pre choices to these. I would like to hear what opinions there are, maybe even from actual owners. I have owned a Shrimp and BAT VK3ix in the past. I definitely want to take a step up. The Calypso is at the top of my budget. I am not able to audition any, just buy and hope I made the correct choice. If it matters, my amp is a Rogue stereo 90 magnum. I am currently using the Eximus DP-1 DAC/Pre and a Salk Streamer tied to Aerial 8 speakers. Obviously I will have to pursue a DAC as well.

I have owned a Herron VTSP-1, upgraded to the max over time.  I traded it in on a VTSP-3A and have upgraded it to the latest version.  As really good as the VTSP-1 was, the 3A (r03) is outstanding.  Until I heard the VTSP-360, I had not heard anything beat or even equal the 3A (r03). 

The best part of owning Herron Audio is that you get Keith Herron.  He provides great customer service and will do what he can to optimize his equipment for his owners. 
From what i am understanding, the modwright anniversary 9.0 is a cut above his other pres. A herron 3 is more than i can spend. I'm afraid the herron 1 is not going to be much different than the shrimp i had. Not really sure why i think that way.
