I’m looking to simplify and improve sound quality over my existing preamp.
With your sources OPPO 103, a Shiit D/A (at <100ohms output impedance) and poweramp Carver Crimson 275 (at 100kohms inputimpedance). A Schiit Sys at $49 would be a great match, and be more transparent than your current preamp, couldn’t get more simpler.
