I've heard their big ribbon system at CES several times and it is superb. I believe the smaller ribbon systems are similar. I would probably follow the designer's suggestion and biamp. Frankly, I don't think there's another company which provides so much for under $20,000.
VMPS speakers
I asked about the VMPS subs a while back and have heard nothing but rave reviews. Now I would like to know if anyone has had any experience with their speakers. In particular the FF1 dynamic version. I emailed them with some questions yesterday and got an almost immediate answer with some questions attached as well. Signed by the owner no less. After 3 emails back and forth I know VMPS is a company I would do business with. However I would have a hard time dropping 7K on a set of speakers that I havent heard even with a 30 day return policy. Please if anyone has had any experience with these speakers or this company post and tell your story.
