JDS Labs O2 - $125
Excellent condition, hasn't seen much use. Simplifying to a combined DAC/amp so I don’t need the amp anymore. Considering it’s size (and price) I’m surprised that I’ve enjoyed it more the Schiit Valhalla I also recently sold. Pushed my orthos and 600Ω Beyers quite well. But you probably know all about the O2's abilities already. Includes Triad power supply.
Price includes PayPal fees and standard shipping to the lower 48 states.
