hi folks.  
i'm contemplating selling my prism orpheus.  this is a pro-audio preamp + dac.  it takes firewire input from a mac running the prism orpheus applet.  the unit is in pristine condition, no marks or scratches, and performs flawlessly.  i will regret parting with it, but i just have too much gear and must start selling off certain components. 
since it requires a particular generation of mac, both firewire capable and running an OS which supports the orpheus applet, i am also considering selling the mac mini and the necessary cabling along with the orpheus.  i will include both the manual and original shipping box, and the (very rare!) apple thunderbolt-to-firewire adapter in case you plan to control the orpheus using a mac with thunderbolt and no firewire output.
i invite those of you who are seriously interested to contact me to discuss the details.  meanwhile, you can google "prism orpheus" and read the reviews.  i think it is a seriously great piece of hardware.
i'm told that i must post an asking price.  in that case:
prism orpheus:                           $2500 + paypal fee + shipping
prism orpheus + mac mini:          $2750 + paypal fee + shipping
note added:  the orpheus can be used WITHOUT the mac mini and firewire connection, as a standalone preamp/dac.  it is currently set up to do that.  digital and analogue input and ouput options are shown here, in the page on the rear panel under "hardware".
