Yeah, they seem expensive at $1700 for your speakers. By comparison you could get highly-rated Townshend Isolation Pods for $1000 but looks like even their Platform or Speaker Bars would be around $1200 and their flagship Podiums would be around the same as the A-Pods. Certainly would make me think twice.
