The stuff looks nice on first glance and has potential, but I find the provided info to be woefully inadequate and the photos are not clear enough. Makes me kindof shy away and lose interest. Just too much work getting basic info. If it effects others the same way, their lost sales could add up.
Why is this sort of thing so common with professional companies -- especially in audio, and especially with Asian companies?
Very annoying. I do a better job with my used gear FS ads! 
I totally agree with you. Product documentation for Chinese company is very inadequate. That's why every year Grant Fidelity goes to China to personally audition products before we even bring the samples to this side of the pond. We don't even launch a product until we test the sample for 3-6 months then write our own description and feature list.
We have personally viewed the Nobility equipment rack in China at their flagship dealer store and are confident with the quality (there are other brands that we tried and dropped before offering this group-buy). We demonstrated some Nobility racks at the 2010 CES (you can see some close pictures on our website) of 4 models we have in stock:

I would recommend people interested in group-buy to stick to simple straight forward design. It's hard to put these products through dealer store so that people can see them in person - shipping will kill the deal and dealers do add up the price. We have to make a trade-off somehow.
But all feedback are well received by Grant Fidelity. We will continue working with factory to overcome these challenges and provide North American customer value added products and services.
Best,
