I am downsizing my study room system so I have a PS Audio Stellar DAC and S300 stereo amp for sale. The Stellar DAC is very versatile. It is a DAC preamp with a reasonably good headphone amp section, and it supports both PCM and DSD if that is your thing. It works fantastically with the S300 that I am also selling (https://www.head-fi.org/threads/ps-audio-stellar-s300-power-amp.892946/). You can find many positive reviews online. Technical spec can also be found at PS Audio. I bought them less than a year ago, so there is still 2+ years of warranty left. The unit is in excellent cosmetic and functional condition. Original double box, paper work, and cable are included. Buyer pays shipping and 4% paypal fee. Local pick up in SF bay area in possible. PM me if you have any question.
