Hi Mr Lee,

I received the power supply on sat....and I just installed it today. It was for my mothers player,

she has the bdp-93 and I have the bdp-95. It's working Great! A noticeable upgrade to the picture and the sound, she

uses mainly the analog outputs for a 2.1 stereo sound with sub for movies with a Ingrated amp. Only issues I had on the

Install of the power supply was the 15pin connector on the supply has to be trimmed to get it to lock in properly and I

also drilled 2 small holes on th opposite chassis to make clearance for the 2 nuts on the right of the power supply. Other than that its

a quick and easy Install.

I would like to order the supply for my 95 for the dig. side of the player.....Your quality work and parts ,pcb board of the supply is Impressive!

Would it be the same price with shipping and paypal. 280.00 ?

Thanks Again!

Greg

Jaehong just to let you know , after install the power suplly I experience a fuse blow , had the heat sink touching the chassis , fix it with some isolation , new fuse and tested fine . Sound and image are excelent (I already had the Nuforce anolog board) and this power supply is a perfect match for this analog board making the sound very close to my MC Cormack UDP1. With the stock power supply there was a big difference between them .

Thank you very much

Marcus

Greetings,

We have now installed your power supply in Oppo 95 with JVB modification. This was not so easy as the JVB mod prevents moving the analog board very far. We also had very difficult time removing the 15-pin connector. A small piece of the plastic connector broke off but it did not affect the wires.

Anyway, it works very well and I am happy. My friend would also like to order one for his Oppo 95. I will pay for it and you can ship it to me like before. I will remit via Paypal as before as soon as you have one ready.

Best wishes,

George

Dear Jeahong,

 

this is my short report on the Linear Power supply kit for the Oppo 93.

I write it, so you can distribute it on the forum, if you wish.

I'm not registered on the forum, so I can not publish it there.

 

 

Report on Jaehong's Linear Power Supply Kit from Manfred (Germany) :

 

I ordered the Linear PS as a Kit from Jeahong from Korea. I paid 152 Euros for the Kit incl. shipping and pay-pall cost.

Custom clearance and VAT in Germany did cost me an other 26 Euros. So in total it was 178,-Euros.

 

1. The Kit and Assembly:

 

The transaction was fast and I received a package which included:

 

1 huge, high quality Transformer 220V, with 2 secondary leads for 6V and 1 secondary lead for +/- 16V.

 

1 high quality PCB with good printings for all components.

 

1 pack with all required parts, as caps, rectifiers, etc incl. mounting bolts and nuts.

 

I had received by mail upfront some pictures and guideline for the assembly. Together with the printing on the PCB it was easy to assemble the kit.

It took me approx. 2 hours to solder and mount all parts. I used Wondersolder and it was very easy to get good soldering joints.

I spend most time to make the caps "naked" and mark them all. If this sounds better, I do not know, but I do this on all my audio kits.

 

I tested the kit and the yellow LED came on, so this should be the basic check, that everything is done correct.

BTW, I should mention, that I do not connect the +/-15 Volt for the analog output, since I do not use them in the Oppo 93.

 

The mounting of the assembled LPS into the Oppo is not a big issue neither, it took me about an other half an hour to swob the power PCB.

In Germany we get the Oppo already supplied with a 3 prong power socket and earth/grounding connection is already done to the chassis.

However, I changed the power socket as well, since I got a 3 prong power inlet socket supplied with the kit from Jeahong.

So I could leave all removed parts in original status to re-assemble it back to original if wanted.

 

Comments:

The Linear Power supply is a non sophisticated, non high-end basic power supply with caps from a korean supplier (non high-end at least to my knowledge).

Therefor I was skeptical about the performance and was hesitating, if I should not replace the caps and rectifiers with better parts, such as Blackgate or Elma caps.

However, then I decided to build it just as Jeahong supplied it and give it a try.

The 2 separate 5V DC for the digital part to the Oppo are filtered/buffered each with 3 x 10.000uF/16V caps, this is really huge, isn't it?

 

2. Video and Audio performance:

 

Jeahong recommended to give the PS some hours of burn-in to settle the caps, which I did with a 4 days x 24hours continuous bluray operation in repeat modus.

 

Video:

(my components to validate are: JVC DLA X7 on 3 mtr wide screen, connected with Wireworld Ultraviolett 6 HDMI cable).

 

Picture quality improved, it seems to have more color and contrast, which probably is the result of less noise on the power supply.

The look is just more 3 dimensional, I think this is the best way to describe it. (I have not tested it with 3-D bluray).

 

Audio:

(I connect with a Wireworld Starlight 6 HDMI cable to an Anthem MRX700 (preamp only) which is feeding an Anthem P5 multichannel amp to a modded Klipsch 7.1 LS-System)

 

High frequency distortion is reduced, much less fatiguing now and lot easier to your ears.

Voice easier to understand.

Speakers are now disappearing better and sound space is more in the room.

At the beginning, I thought that bass has lost weight, but it is just less boomy and more precise.

I can turn up level now by 3 to 5 dB and still thinking it is lower volume then before the upgrade.

This is a clear indication, how much less stress is put on your ears with the LPS.

 

3. Summary:

 

The Kit is a no brainer for everybody who wants a cost effective upgrade for his Oppo 93.

It is easy to install (and to assemble if you can hold a solder iron).

The performance improvement is surprisingly big, especially when you compare it with the cost of "professional modders".

After the LPS in the Oppo 93, it is very difficult to listen to any SMPS equipped blu-ray player anymore, its just pain on your ears.

 

 

Jeahong, please fell free to use my report as reference to other possible customers or on the forum.

Thanks.

Hi Lee

Thank you for your email.

We have been testing the linear power supply over the past few days, and the improvements to picture and sound quality are very impressive.

All of the benchmarks for picture and sound are up several points; Texture, Dynamic Contrast, Sharpness, Fluidity, etc.

When watching a HD nature documentary the improvement to picture depth is most striking, the images look more 3D than 2D. Also natural elements like water, ice, snow, wood, look more real!

The sound quality of movies is also greatly improved, more clarity, better depth, improved dynamics.

We are very pleased to have worldwide distribution and are now making the necessary plans to get the product to the market.

Thank you for your report of the modified OPPO 93 and MSB player.

Did you observe any picture quality differences between OPPO 93 and MSB player?

When do you think the OCX board will be ready?

Today we received the second power supply module. We will install this in another 93 and make further tests.

Best Regards

Mark Bartlett
