Last week, I bought a Yamaha Natural Sound DV-S5550 DVD player (the DAC was designed for DVD Audio). The only problem was that the tray was jammed (easy to fix).
When I examined the electrolytic capacitors on the "A" board (DAC/AV outputs and Digital OUT) and the power supply, the only two audio grade capacitors were 2209 and 2229 (Both audio coupling). The rest were general purpose units.
All of the capacitors on the "A" board were replaced with audio grade units, with the following upgrades:
2301, 2240, 2310, 2306, 2319, 2315: 1000uF 10V
2317, 2318: 1000uF 16V
The power supply secondary side capacitors were replaced with low-ESR units, with the following upgrades:
2280, 2215, 2255: 1000uF 16V
2230: 3300uF 6.3V
2235: 1000uF 6.3V
2250: 2200uF 10V
2210: 2200uF 16V
2240: 100uF 50V
If low-ESR (power supply) and audio grade ("A" board) capacitors are used, the sound would be a bit more "natural".
