This is a very accurate, pleasing way to play computer audio.  Metrum Octave Mk I NOS DAC is well matched with the Stello U3 USB to SPDIF converter.  The Octave-Stello combination is never harsh or strident, and is cleaner/clearer/quieter with the Hynes power supply made for the Octave.  Perfect match for PureMusic.  I'm hoping to sell this together as a bundle.  There is no discernible wear but the cases are not absolutely mint, so a strong 8 rating would be about right.  $1250 for the bundle.  
Wywires USB and SPDIF wires to tie these pieces together:  $500.
