The listing

Fosi Audio ZD3 DAC + ZA3 Amplifier + Sparkos & Burson Op-Amps Selling my Fosi Audio ZD3 DAC/preamp and ZA3 power amplifier setup, including a large collection of upgraded discrete op-amps and accessories. Everything works perfectly and sounds excellent. I have over $500 invested in the complete setup and upgrades. The ZD3 and ZA3 make a great compact balanced desktop or 2-channel system. The ZD3 uses the ESS ES9039Q2M DAC and supports USB, HDMI ARC, optical, coaxial and Bluetooth inputs, with both RCA and balanced XLR outputs. The ZA3 can be operated in stereo or mono and includes both RCA and balanced XLR inputs. The real bonus here is the collection of op-amps for experimenting with and tuning the sound. Included are: Sparkos Labs SS3602 discrete op-amp Burson V6 Vivid discrete op-amps SX52B op-amps Additional IC/discrete op-amps shown in the photos DIP-8 sockets/adapters and extension leads Original op-amps 48V / 5A (240W) power supply for the ZA3 ZD3 remote control Original ZD3 and ZA3 boxes The ZD3 and ZA3 are specifically designed for replaceable/op-amp rolling, so you can experiment with different combinations without modifying the equipment. The upgraded Sparkos and Burson discrete op-amps take an already very capable Fosi setup considerably further. Both units are in very good used condition with only minor cosmetic signs of use. Please see the photos for exact condition. Prefer to sell as a complete package. Local pickup in Southern NH/Nashua area. Can also ship at buyer's expense.
