One of my big regrets with gear was selling my Orpheus when I bought a Mac computer, thinking I was trading up to an Apogee. Months later I had the opportunity to A/B the Apogee with a friend's Orpheus and we both preferred the Orpheus.
The only other unit I was considering was the Lynx Hilo (I already have preamps so it seemed wise to save money and go with Lynx instead to Prism). But yesterday a friend of mine loaded the audio samples from this thread onto his system and we compared them; Lynx Hilo, MH LIO8, Orpheus, Lavry Black Shootout (Music & test tones)
We both thought the Orpheus sounded better than everything else - except the Lavry Gold. I can't afford the Lavry, but as a quality-driven, home studio owner recording high-end acoustic instruments, I'm convinced that Prism is the best I can do.
One other plus about the Lyra2; I can use those preamps in addition to mine if I ever need to record more than two tracks at a time. Frank Oglethorpe told me that that both Lyras have two analog inputs but the Lyra 2 has digital i/o capability too. So if your outboard pre has a Toslink, SPFIF or ADAT output you will be able to get up to twelve inputs at 44.1/48, eight inputs at 88.2/96 and four inputs at 176.4/192.
Y'all do what you want, but I'm buying the Lyra2.
