Gentlemen, if you will permit the designer to say just a few things.

Most of all, I want to thank all of you for the time and effort you have put into getting the best out of the Bijou. And for taking the time to listen to lots of music to really evaluate its SQ. I have, of course, been reading your comments (which are consistent with my sense of the amp) and have been grateful that the amp has been worth your effort.
And, I really appreciate the offer of the emblem. I am happy to receive it.

I have thought about a commercial version of the Bijou, but I'd like to wait a little while as I am working on two other projects right at this moment.
However, with regard to a commercial Bijou, there is, unfortunately, a British company that markets a headphone amp called the Bijou. I chose this name a long time ago, but they might have TM protection on use of the name. I haven't looked into this in detail, but it could be true. Would be great if it's not though.
In any case, thanks again.
