Aesthetix Calypso vs First Sound Presence Deluxe

I would like to compare the Calypso to the First Sound Presence Deluxe. I have heard the Calypso at a dealers showroom but I have yet to find a dealer For the First Sound. Both preamp are around the price point I was looking to spend. Both get wonderful reviews. The Calypso has balanced inputs and outputs and a remote control which the First Sound does not. The First Sound has a outboard power supply and is a little cheaper, plus can be upgraded very easy. Both of the preamps seem to be at the top of the class in this price range. As I said before, I have not heard the First Sound, which I hope to.
I Would love to do a side by side comparaison at home in my own system, but without a dealer for the First Sound in my area that seems impossible. Am I missing anything not hearing the First Sound ? I was very impressed by the Calypso, and this was just at the showroom. I haven't heard it at home yet.
Which Preamp will deliver more warmth, Bloom, detail and soundstage ?
My current system consists of Audio Research VT 100, LS16mk1,PH3SE,VPI Scout, Marantz 8260 sacd. All cables throughout are Virtual Dynamics Masters. Speakers our Audes Grand Blues. Room size is 29x24x7.
Thanks for any input. Brian
