I listened to the Orpheus 2 at the Sennheiser store in San Francisco on Saturday. It's by appointment only. No walk in's. The listening room is on the 2nd floor. It's a large room that's almost completely empty. They have the original Orpheus there to but it wasn't connected. It was there just for show. Besides myself there was only one other person in the room, a store employee named Miles. The sources were Tidal through an Apple laptop and a Clear Audio Ovation turntable. Each appointment is 30 minutes in length. I hadn't prepared any play lists for myself so I just selected tracks I familiar with. The first was Art Blakey "Live at Birdland". I don't use Tidal so I don't know what the resolution was but it sounded a little flat and lifeless. I next listened to a vinyl record, "Blue in Green" from "Kind of Blue" by Miles Davis. It sounded truly bad as the Orpheus is so resolving that it was picking up every flaw in the recording and in the pressing as well as needle drag through the grooves. That was to be expected though. High end headphones and vinyl are not particularly compatible unless it's very well recorded, mastered and pressed (re: Music Matters Jazz). I'm not a bass head but I did a bass test anyway with "Chameleon" from Herbie Hancock's "Headhunters". Sub bass is weak and, like "Live at Birdland", it sounded flat. The last track I listened to was from the Argentine band "Sera Una Noche". They only have released 2 albums but both are extremely well recorded. Now the Orpheus sounded like what you would expect. It was the most transparent sound I've ever heard from any headphone or speaker. It sounded absolutely live. I only heard the piano, I only heard the guitar, etc. It sounded completely realistic. I was just amazed.
As for the mechanical attributes of the amp, you press the button to turn the amp on and first the buttons slide out of the amp, then the tubes emerge and then the lid rises revealing the headphones, and it's all completely silent. The phones are a heavy but comfortable, a little like an LCD 2.
Would I buy one? That's a moot point since I can't afford it. But even if I could I can't justify spending 55 grand on a statement piece with all the hunger and misery in the world. Listening to the Orpheus 2 underlined an issue with ultra high end audio, the higher you go, the less music you can listen to. Only the best recorded music will make a high end system worth listening to. But with a mid-fi system you have much more music you can listen to and enjoy, which, as far as I'm concerned, is what it's all about. I still have to give Sennheiser a lot of credit. The Orpheus shows what's possible.
