I've heard a few of them. The Ah! is my number one choice for under $1000. Not as detailed as a big bucks player, but very very good and nice to listen to. The model I heard had all the options except the 24/192.
For high dollar tubed players the Audio Aero 24/192 and the Metronome C2 are both absolutely wonderful. Another player you should definitely consider is the Audiomeca. I used to own the Enkthuisas 24/192 and have heard it back to back with the capitole mark I. The AA sounded more tubey, but in absolute terms I would call the equals. I myself slightly preferred the Enkthuisas, my friend who owns the AA greatly preferred the AA. On a different day I could probably choose the AA.
