Artemis Labs LA-1: Anybody ever audition it?

I have read some very postive reviews of the Artemis Labs LA-1 linestage. However, like always I take professional reviews with a very "big grain of salt", and seek out the opinions of my fellow GON members.

So, has any one seriouly listened to the Artemis Labs piece? If so, what was your impression of it's performance? Do any of you now have it in your system and if so, what did it replace and why?

Thanks, for any information that you can share.
