Headphoneus Supremus
Just saw this on their site. Interesting as I love the form. I have the regular National and love that thing. Wonder how this will stack up against it and the myriad of others with this form and output. I am considering the RXMk3+ but may seek to upgrade my regular National to give this a try. Price seems a little steep at $400...
