Aesthetix Calypso Signature vs. ARC REF 3


I am curious if anyone has made a comparision between these two pre-amps. How would you describe the differences?
Sonic as well as build quality, maybe last pre-amp I buy.

Take a look at the build quality of a Pass XP10 which is my current preamp. It is solid state, I admit. But there is no comparison to Aesthetix--Pass is light years beyond and is a company that has been around for a long time. The OP is looking for "the last preamp I buy" and I would not put the Aesthetix in that class based on my experience with it--hence my cautionary note. Not to dismiss the many positive reviews and fans out there who enjoy the Calypso and its sound quality. But like the OP I was looking for my last preamp ever (maybe!) and I think the Pass is it. To each his/her own, as always, and caveat emptor.
I do wonder what it is about the Aesthetix preamp that makes it so prone to comments like, "with the right tubes...." This label seems to have stuck in a way that you don't hear about other tube preamps (certainly not to the same extent), even if you are a tuberoller. If true, it would be one reason for me not to choose it, especially for a lifetime pre, where those NOS beasties will be getting scarcer and scarcer. If a preamp can't sound goos with current production it would be off my list - even if I do use NOS.
Thanks Guys, a lot of food for thought, I had been leaning towards a REF 3 but the Calypso keeps coming up as a suggestion. I have a LS26 now and if ARC doesn't come out with an LS27 soon I am looking for the REF3. My dealer has me on his list if he gets a trade. I have never heard the Calypso but the comments here have kind of guided me back to the ARC route. I have heard one in my system and loved it but, we always want more right? The only other consideration is the McIntosh C500T, but never heard one either. It is easier to buy a 40000 car than a 10000 pre amp, since you can go to dealer and he has one to test drive. Audio companies should have demos that you could try at home for a week. It would be worth the freight charges, and I would think for them it would increase sales.
i'm a new calypso owner - stock tubes - am am EXTREMELY impressed with it. i don't find it lacking in build quality or sonics.

@ Pdreher: "and with the right tubes, it sounds great." would you mind elaborating what you tried and found?
funny how these threads go...the Calypso's build quality does not take a back seat to any preamp on the market. The term "sounds good with the right tubes" really means you can dial it in to your system and your taste. When NOS tubes disappear "in the next who knows..50 years"...they will be replaced with better tubes if there is a demand.
I found the stock tubes to be very good...but lets face it, most of us like to screw with every detail in our system. The Calypso gives you the freedom to do so, it is a very good preamp and easy to maintain...almost as easy as solid state. I have owned all the Pass Labs preamps until the current XP generation. I loved the X-0.2 but the Calypso gives more of a real flavor to the music in my system.
