I called Wadia about the warranty, and the service tech is extremely professional as well as friendly.. Steve Huntly use to work for Wadia, and has always kept a good relationship with them, mutual admiration if you will. I use to own a Burmester 089 and a close friend a Burmester 069 w/ power supply. Both , IMHO, are not as engaging as my Wadia GNSC S7i Statement. There is just a little more detail and less romantic tube like sound, and of course that famous Wadia slam in the bass. Thank-you Roysen for your post, most enjoyable. Waia is also working on the new 24/192 chipset for the S7i. The S7i already has a usb port, but I do not know if it will be upgraded ( edit-yes it will). I must also add the Austrian transport is a joy to use and built like a Panzer tank. I was devastated that Steve had to shut down. I bought my S7i only because of him. Steve also heavily modded an Esoteric transport for Mike at Precision A/V, which incidentally have received numerous best sound of show awards.
