I have a Quantum DAC which gives the current Resolution products a run for their money even though it is based on the Ultra Analog chips (no longer around) rather than the Burr Brown's.
These can be had for less than a grand these days (originally sold for $3200). I plan to pick up a second Quantum and a Resolution Cesium transport and run in a balanced format. One DAC per channel. Takes lots of PC's since the Quantum has separate power supplies and cords for analogue and digital sections. Less than 3 grand and it slays.
Now I'll add that I am really re-focusing on analogue and my priority is upgrading my nearly new (but used) Oracle table to full Mk V specs and spending real money on a great cartridge.
