gonefishing999 Posted August 3, 2018 Posted August 3, 2018 (edited) 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. @ghost4man @djb @jamesg11 @evil c @buddyev @Addicted to music @scumbag @maxdc @Black Orange Edited August 3, 2018 by gonefishing999 4

gonefishing999 Posted August 3, 2018 Author Posted August 3, 2018 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 . 1
davewantsmoore Posted August 3, 2018 Posted August 3, 2018 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.

Both SSR and Oppo using I2s have improved sound stage producing depth, image, air, decay and seperation of instruments. Spdif has none these qualities. Edited August 3, 2018 by gonefishing999 1
gonefishing999 Posted August 3, 2018 Author Posted August 3, 2018 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. 2

gonefishing999 Posted August 7, 2018 Author Posted August 7, 2018 @TLL I have not seen this board that's on ebay. This is easy way to get I2s out of the Oppo any model. I prefer the Oppomod board as it takes the I2s before any conversion by hdmi no limits on pcm or dsd , so this is the purest way of audio.
TLL Posted August 9, 2018 Posted August 9, 2018 The oppomod board should be a better implementation to extract the dsd data out, I'm going to buy one as well 1
Addicted to music Posted August 9, 2018 Posted August 9, 2018 I’d like to experiment but at this point in time I do not have i2s devices.
gonefishing999 Posted August 9, 2018 Author Posted August 9, 2018 @TLL You will not be disappointed the SSR was $4400 landed and it betters that. To use the I2s board the main clock needs changing ,I will be making my own tcxo clock board cheaper than Oppomod if you are interested.
TLL Posted August 9, 2018 Posted August 9, 2018 Yes, this is my plan to change the clock as well. I have good results in modding my dac with the crystek cchd-957 series clock which you may like to consider. You can buy from mouser. For the PS, I have some TPS7A4700 module from ebay https://m.ebay.com.au/itm/TPS7A4700-Low-Noise-RF-Power-Supply-Module-DC-3V-3-3V-5V-12V-15V-1A-Adjustable/332444010447?hash=item4d673507cf%3Ag%3Am94AAOSwyi1a0ckW&_nkw=TPS7A4700&_from=R40&rt=nc&_trksid=m4084.l1313 Need to buy the 25MHz and 27MHz clock, if Im just using hdmi 2 for audio, do I need to replace both clock? The clock is surface Mount, have you source any SM board/adaptor to mount the clock?
TLL Posted August 9, 2018 Posted August 9, 2018 Oh, just check the mouser catalog, crystek do not have 25 or 27MHz clock

gonefishing999 Posted August 12, 2018 Author Posted August 12, 2018 @TLL I can get 27 the same as oppomod uses in tcxo and ocxo . I need to order 10 pieces to get ocxo if anyone wants to make this. 10 12 weeks for delivery. I wii be ordering this week. I will design circuit boards this week to fit both clocks.
gonefishing999 Posted January 12, 2019 Author Posted January 12, 2019 (edited) A few people have PM me as to how I use Oppo as a streamer. First I was using a Qnap nas with Minimsrever , Bubbleupnp server , Ipad with Linn Kazoo. Kazzo looks for Rooms "openhome" servers so bubbleupnp will find Upnp Oppo when selected you can select to make it Openhome so Kazoo can find Oppo. Kazoo can play Tidal . I found Qnap and bubbleupnp very flaky, so I have an Intel Nuc Win 10 with Minimsrever , Bubbleupnp server installed work like a dream no more problems. Hookup Nuc Wifi cat6 to Oppo or Wifi will do. The Intel Nuc was chosen as it has a 12v dc supply so linear power supply can be used an no internal PS. Nuc I use is an I5 4 Gen 4Gb ram 120 Gb msolt and 2.5 3Tb. NO usb as this will degrade sound. My option only many might think differently. @ghost4man is using same setup as me his Nuc is a Celeron 7Gen 1 min to boot thats all other wise no difference to my I5. Nuc can boot with Minimsrever , Bubbleupnp server if these are added to start menu. Just hit power button no monitor required to start streaming. You can use Roon but have not tried it.

Spdif has none these qualities. I use the VanityHD with an Oppo 103 to feed a DAC via Coax, but am very interested in adding Dr. Lee’s I2S board if possible. I wonder if the mods are mutually exclusive, or if they can both be implemented in the same unit.
gonefishing999 Posted January 23, 2019 Author Posted January 23, 2019 @Mjay Yes it will work fine, the ribbon cable out of Oppo main board goes to I2s board then another ribbon cable runs to VanityHD board. Peter 1
