Hey allJust recently me and my father both bought a audio interface at the same time so I could compare them, he got the RME and I got the Prism Orpheus, Ive decided that I cannot notice much difference between the two to be honest, there is a little more clarity/shine in the Orpheus especially at the top end. But I prefer the ease of use and interface of the RME which ill be using with other pre-amps and love its extra built in effects etc so decided to sell this on.As listed in the item condition there is an audible mechanical hum from the power supply which you may want to get fixed, the device is working ok like this and was going to send it off to get fixed but don't have the money at the moment. The noise does not appear audible on the recordings so this Prism is fine to use. For those of you that can hear it it may become annoying if your recording in the same room, if in separate room or larger room no problem.Firewire cable included and Firewire converter from fw800 to fw400 which was needed to use the Prism with my Laptop.Thanks for looking and please feel free to ask any questions.
