Thanks for having me Joe!
Let me know how that Berkeley DAC sounds. I hear they are backordered but doing another production run. I was talking with the owner a few weeks ago and I owe him an email. I had thoughts of becoming a dealer locally for that but then backed away.
I decided to go with Weiss for the USB to AES converter for my Avantgarde Acoustics ZERO 1. I've had those for a few days now and they really are an amazing speaker. Still getting to know them.
My main system is a Weiss, Sound Lab and NuForce Reference 20 based system. I've never had horns before. I used to run my Sound Labs A-1PX electrostatic speakers with Atma-Sphere MA-2 MK3.2 OTL mono blocks but went to NuForce class D last year in the fall when I needed to retube and was having trouble finding enough of them. I tried a pair of Reference 20 amps while I was waiting for tubes and I liked the sound of the class D amps better.
I would have liked to try your Devialet but it's only rated down to 2 ohms so the Sound Lab panels would give it grief I think Around 1 ohm for a brief period of time. Devialet makes nice stuff though! Listened to the Phantom a few weeks ago at the Montreal Audio Show. I might put those in th living room for fun!
