I'm rocking the Touch with an EE Minimax DAC and am quite content with the pairing. My suggestion would be be dropping the $750 on the DAC and the remaining budget on digital modifications from Bolder Cable for the Touch.
The DAC and mods (along with a Siemens Silverplate and Wywire cables) have my digital coming much closer than it should to my 10x more expensive analog rig.
