Upgraded Power Supply for Darbee DVP-5000S

Yes you will see some difference prob less noise if their are any present in the video images when put on still mode.

Technically speaking, engineer types will normally say that a linear power supply for this HDMI digital processing will not have any benefit in quality.  However, there are some who say that linear power supply will help video quality (such as those who have done the linear power supply mod on an Oppo bluray player).  Also, some say that switching power supplies can have a negative impact on the rest of the audio equipment (creating switching noise on the A/C line).
