I auditioned and put in an order for an Emotive Audio Epifania linestage. I have no idea about it's topology, except that the manufacturer claims that the signal passes through only one output tube and somehow the output impedance is kept very low without the use of a cathode follower.
The Epifania can be ordered with several options -- with or without teflon caps (quite expensive), manual or remote control (volume, balance, mute and input switching), and choice of wood for the base. The base model is something like $17,000.
As far as I know, it has only been reviewed once, by the recording engineer Steve Hoffman, for the on-line magazine Tone. I believe this is the same person who has given rave reviews to WAVAC amplifiers so he is on the same page as you are.
