Prism Sound Titan by patysteve
The Prism titan sounds wide, 3D, very pleasing and detailled, with firm but extended bass response. It don't get hot, is silent and rackable. It sounds extremely well balanced. very easy to mix with it.
The software is excellent and routing is complete, usb is very stable with w7 and w8.1. Mdio expansion slot for Protools and usb make it futureproof. Never tried it on Macos.
There are a lot of usefull things (complete monitoring controls, Overkiller limiters and M/S encoding on every line in, standelone mode, sample-rate conversion, Adat and S-mux ...)
New price is very interesting at this level of quality and when you consider all the options. For me the perfect interface. Very happy with my purchase.
