The Wave 8 was developed as promotional items and has been in the market for too long. It was at last been discontinued.
I still have one pair cover new in the box and one pair demo that probably is a keeper.
Interested in my last new pair please e-mail me at

After this is gone, the closest design is the World Audio Kit kecl82 which is a stereo amp and kit only and selling for UKP 195.
