Yesterday I had a chance to listen to the cap mod (lots of ELNA, Nichicon, Red German WIMA and silver MICA) of the version 1 ZERO. all I can say about the zero is very nice piece of works.
The transparency become very obvious and I like the way NILS LOFGREN pluck his acoustics, with conviction and weight. The vocal is more natural and overall it is very musical. Bass has more attack and more control.
1. Diode Bypass (reduce noise)
2. Stability and Noise killing mod for digital section (PS bypass replaced with Silver Mica)
3. Ground loop breaker mod (better caps)
4. More capacitance for the main analog stage, from 4400uF to 6600uF
5. More capacitance for the digital stage with Silmic II parallel, from 2000uF to 2330uF and bypass.
6. Cap replacement on analog output stage
7. Film cap replacement with german Wimas near the clock, DAC and supply lines.
