Another DAC suggestion a step above Metrum Octave

I currently own a Metrum Octave and looking for a dac that is clearly a step above the Metrum. Tube or SS, new or used, budget is $3k.

Utmost importance is more refinement than the Metrum. I also use a reclocker with my dac.

Please choose one from the list or add if you feel you must.
AMR DP-777 (maybe a little out of range)
Audio Research DAC8 (very very curious over this one)
PS Audio Perfectwave MKII (in my Oppo-95 days, did like Sabre 9018 sonic signature)
Berkeley Alpha I or II (don't really know what to expect)
Chord QuteHD (seriously don't like it needs a separate quality linear power supply to sound its best, why can't Chord use standard IEC connection like everyone else)
