Randy,
The Billie's are just getting started. Heated up the soldering iron today for the first time since I got them. It's slow going, because they change parts on these often, and the documentation does not get updated.
I will get my Belle's next week probably Tues or Wed. - You know I did this after hearing your K-Horns! I did like the 'large' sound. I am missing that with stand mounts. I would have went for the K-Horns, but I just don't have the proper corners. Hopefully the Belle's will provide me with a lot of the K-Horn experience.
Yes, AVA does require payment in advance, but I know Frank has lent out gear to Minneapolis/St. Paul Residents for a few days (including myself). Send him an e-mail telling him that you heard my T7 for an hour and that you would like to hear a loaner for a couple days. He may give you one!
