I'm in the market for a direct box or two and being an American, I am of course very curious about the item with the large large price tag: the Aguilar DB900 tube DI. Does anyone have any experience with these? I see that they get raves from magazines and so on, but we're not exactly talking about chump change. I have to wonder what specifically is so great about them. Super functional? Really hifi? Really great colored tone? What problem do they solve that a mic pre with instrument input such as the FMR RNP doesn't? I am a recording equipment gearhead and I am no stranger to what a $2500 mic preamp brings to the table, but I haven't seen a lot of info on these.
