Hey, Miles.
The Lyra Atlas is not yet released. It will be very soon. It's the new top model. Stig say they will probably stop offering the Olympos once the Atlas is in production.
The Spectral Audio SDR-5000 is only in prototype stage too according to what I have heard.
I also forgot to mention this Weiss/Maya DAC - http://www.audioasylum.com/audio/digital/messages/15/153684.html
