I was the person that didn't like the JoeCo box. Sorry I didn't get back to you personally but at the time, there were a ton of PMs about it and I guess I missed your's.
First, I think it's interesting that you would think that I didn't like it because of the price. Wow! Why would you assume that I didn't have some real technical issues with the BBR1? I wish my thrift was the case; I would be a lot less in debt if price was the issue on gear I bought
The 552 and the BBR1 are two completely different pieces of kit; seems pretty obvious to me anyway, and that maybe an engineer would have them both if he did enough different work to justify the expense of owning both. The BBR1 wouldn't fit into a ENG bag very well, and I'd hate to carry around 24 units of RF receivers to fill up the inputs
Nor, as you stated, would the 552 be the proper device for a large multi track job.
I worked very hard at not trashing JoeCo at the time; I certainly had one of the early units, and all involved with my purchase and return, JoeCo, the US distributor and the retailer, were absolutely professional about the whole situation.
It just didn't do the job for me. It had some real problems; a clock that failed, some build quality problems, and a user-interface that I just didn't care for. That's it. Just wasn't my machine. Bought a vintage Mackie MDR and it seems to do the trick; yes bigger, heavier, and all. But it is the machine that does what I need how I need. That's the thing about sound kit. No two of us do it the same.
If you need a multi-track machine, I fully endorse your right to check out the JoeCo
It is certainly a brilliant idea whose time may/has come. But if you need video/film production sound kit, I believe that you will find ANY of the Sound Devices units do their particular job elegantly, professionally, and sonically, and you will be hard pressed to find such an array of capable equipment from any other manufacturer.
