I have in the past made speaker stands for several speakers (different brands) and tested lots of different designs and ideas. In fact, I started that about 30 years ago, for personal use and for friends and family. I do enjoy working with metal and have access to advanced welders, lathe and milling machine (both not so advanced!), band saws etc. So I can create physically most of the ideas that come up in my head.
The original idea for this particular project was to make a high performing stand for the JBL 3677 speaker, at first for Christian here on the forum. After a lot of testing of materials and design solutions, I have come up with a stand that perform at a level that I feel comfortable with to sell. The name, well the product has nothing to do with Linn, so I just cut that part away! The standard stand is now called Ofil Stands FMT x677.
I have sold a few pairs to forum members and even to one individual (with part Lejonklou system) that is not on the forum. The customers who have provided feedback have been very happy with them. I will let them provide their own feedback here if they feel like sharing their impressions of the stands and the performance benefits.
Here are some pictures from the prototypes:

This is with the standard top plate that turned out to sound the best.

This is one lightweight prototype top that I tested, not good...
These are from testing some different parts and different designs:



This is a prototype with a smaller footprint. Did not sound as good as the final design.
The stands are entirely hand made by me and are more like individual artwork, than mass produced factory made stuff. This might not appeal to all and I will let others describe the level of quality they feel when they get their stands. At the moment I'm selling these as a private individual, not a company. The volume is just to small for anything else.
