Someone mentioned the Digital Card...
I own an ATB 24 and spoke with PMI because I was doing some mods (ok , not perfectly relevant, but this)...
I'm pretty sure PMI decided NOT pursue doing the digital option for the console, even though hey still (as far as I know) have that space in the console.
Just for your inforamtion.
My opinion of the Toft ATB is a BIG
IMO, the best positive contribution you can make to your sound for the money spent.
(In other words, the biggest bang for your buck!)
