I am pretty bitter right now, dealing with a small company on expensive purchase: TacT. I bought the original TCS version for $10K. It had problem locking to incoming signal. Was told there is no solution but to upgrade to MK II version for another $6K. Paid that. By the time the unit came back, I had an Anthem D2 processor so it sat there for a year or so. I eventually decided to power it up, only to find the front channels not working.
Contacted them and Boz basically said the box was obsolete and there was not much he could do. I swapped out the DSP cards from the Aux channels and got the front channels working.
The box sat for a few months until last week when I tried to power it up. More channels had gone bad. After searching through, I found two working channels there. Happiness didn't last long as after a few hours I lost one of those channels too

.
Desperate, I asked the software to re-flash (download) the firmware. That worked, the box rebooted and then got stuck in an infinite loop on start-up, no longer doing anything.
Searching online I find someone with the same problem. He said the firmware image was bad that came with the software and that he contacted them and they sent him the right version. Becoming hopeful, I did the same.
Well, I get an email that says to use the same firmware I already had tried to use. So I call them and speak to Boz.
He tells me I had no business upgrading the firmware. And that it wouldn't fix my problems anyway. I ask what would. He basically says he doesn't know other than must be some communication problem between the two modules so it must be a hardware problem.
Since the machine is quite modular, and these DSPs sit on cards, I ask if he can send me the main board to try. He says no. I ask why. He says he doesn't have as parts have been discontinued. I say surely he must have some spare parts or other machines sitting around. And he says no.
I ask again what I can do to reflash the unit at least so that I get back to where I was. He can't offer any solution. And keeps telling me I should not have tried to upgrade the firmware. I say that the upgrade is a feature of their software. I only selected that option and it did everything itself. I didn't even have to download the firmware as that version came with the software. So surely this is not a case of me breaking something.
I take the box apart and take a look at the main DSP board. I see that the flash memory that holds the firmware has been reworked/replaced (hate to see that with surface mount parts). And looking carefully, it shows that two pins have been shorted out with a solder bridge from sloppy work there.
I remove the short but still nothing.
I contact Boz and he says he is going to Europe and will get back to me in a week.
So here I sit with a $16,000 paper weight.
To add insult to injury, I tried to join the Yahoo group for TacT and it requires approval and no one was approving me.
So guys, please run away from small companies making complicated or expensive products. It just isn't worth it. If you are buying a $500 thing you can afford to throw away, fine. Otherwise, be very careful.
