USB seperate power cable and linear 5 V adapter.

 When you have my  linear power module in your OPPO player, you have to use this clean linear powered seperate USB cable for using external hard disk driver.

 

The external hard disk driver has it own tiny switching power to feed the hard drive ( usually more than 2 T byte) .

When you connect this to your linear powered OPPO plyer, the noisy  5 V comes through common USB cable.

So this is the solution.

 

1. seperate USB cable

 

It use high quality copper wire and thick gold plated terminal for high end audio users

 

2. Linear 500 mA - 1 A  5V regulated power adapter.

 

Unfortunately the linear power I baught in here needs to be modifid.

so I did with Nichicon KW audio grade capacitors and WIMa film capacitors.

 

 

 

The result is very impressive.

The transparent and color of video and sthe detail 0f sound quality is greatly improved.

 

It is simple and easy, try .

 

This combintation is also very effective for PC-FI when External DAC is used with notebook PC.

It prevent to flow noisy 5 V power from NOte book PC to external DAC.

 

I can sell you this seperate USB power cable and upgraded 5 V linear power adapter  for 100 $ to those who have my LPM , free shipping world wide.
