Just picked up some Beyerdynamic DT770 PRO Closed Studio Headphones and thought I'd check out for a DAC USB unit for the PC. Looks to be the best price to date according to older Ozbargain (https://www.ozbargain.com.au/node/829751) deals and CamelCamelCamel with the 15% off Mid-Sale.

Looks like Creative Labs themselves are throwing in a Sound Blaster Blaze V2 headset worth $69.95 RRP with each purchase.
