Oppo 203 HDMI I2s

Recommended Posts

I have a Holo Spring Dac and has I2s input.

The soucres I have used are as below:

Oppo 105 Xlr Out

Oppo 105 Spdif out

Sonore Rendu Network Player I2s Hdmi out

Sonore Signature Rendu I2sHdmi out

Oppo 203 I2s Hdmi out

This all started with trying Oppo 105 Spdif coax into Holo. I was surprised how much better coax sounded

compared to the Saber dac , I knew if I could get I2s out of the Oppo, so after a lot of google looking I asked

Jae Hong Lee from Oppomod if he could give me schematics  but after quite a few messages on Diy Audio

Forum I asked if he would make this board for and it took about 5 months for him to have it ready for me to try.

Here is pic below.

I was extremely happy with SSR and thought I might be able get better results

with Oppo so the results are below, it has taken me a lot of time comparing SSR and Oppo

get up change hdmi from one to other but upon listening the difference was significant.

I didn't want to do this post until I could put into words what I was hearing so this morning

I sat down and wrote down what I heard.

SSR compared to Oppo drums sounded muffled,further back, recessed.

Oppo the drums are more forward clean ,clear ,distinctly hitting skins, more punch dynamic.

Over the sound is cleaner, clearer, better separation between instruments and voices, cymbals

go much higher.The total sound is more realistic .

Have you auditioned the difference between:

Oppo connected via SPDIF to the Holo  VS    SSR connected via I2S to the Holo

 

It would also be interesting to audition:

Oppo connected via I2S to the Holo  VS    SSR connected via SPDIF to the Holo

 

 

Assuming you have remote input switching on the Holo, then you could set up an audition where you can cue up the same track on both sources, and the remotely switch.    Do make very sure that the SPL output from each is the same (you will need to do better than matching them by ear).

 

 

The reason that I ask, is that it may be that the I2S implementation on either that is leading to the obvious sound difference.   From what I can read about the Holo DAC implementation, it would be especially sensitive to these things.   I2S can be incredibly shaky ground at the best of times for getting acceptable performance.

I showed Jae Hong Lee following pic that this is the I2s output I wanted which he has done.

Does it make any difference whether I2S or SPDIF?

Both SSR and Oppo using I2s have improved sound stage producing depth, image, air, decay and seperation of instruments.

Spdif has none these qualities.

Second mod I have done to the Oppo is replace the main board clock.

I2s uses the the from the source player so the better the clock the better the sound will be.

The sound before installing the clock was bright in upper mid and top end and had a bit of bite to it.

Once I removed the clock and putting in Oppomod TCOX it sound is the best my system has ever sounded.

I was quite excited so started  going through a lot of ripped cd's to hear how incredible they sounded now.
