If the SU-1 is sitting on top of the Holo Spring by itself, would this cable have the flexibility to go out of the SU-1 into the Holo Spring?

 

Yes, it works but the cable has to be twisted to make it work and ends up putting a slight torque on the HDMI ports.  It's probably okay, but I'm not entirely happy about it.

I ordered one of the 1 ft ones just to test against my go-to (Nordost Silver Screen 1M).  I wonder how the DH Labs ones would do...they have/had a model that had swivel (up and down, not 180 degrees) connectors so the pressure would be less.  I have one on one of my video connections, I may try and report back.

This one has flexible connectors but only comes in 1 meter and up lengths.

Another question I have is the cable length.  The SU-1 has to be pulled forward to allow enough room for the ISO REGEN connected with the 90-degree USPCB to rest on the Spring DAC chassis.  I think a 0.3m cable could work if the HDMI ports of the DAC and the SU-1 are vertically aligned to minimize the reach, but the cable would have to be flexible enough to avoid putting too much strain on the HDMI ports.  @Superdad, do you have any thoughts on this?

 

 

I am having a little trouble visualizing this.  Instead of pulling the SU-1 forward why not push it as far back as possible so that the rear of the SU-1 and Spring DAC are aligned.  Then use something like a small block of wood to support the IsoRegen?  I use a 0.3m Wireworld Ultraviolet cable and aligned  the HDMI ports.  There is nothing directly below the SU-1 USB input port so there should be no interference with the IsoRegen.

I've toyed with the idea of getting two 90 degree HDMI adapters.  That would allow the hdmi cable to connect vertically to the SU-1 and Spring DAC without the need for any sort of bend anywhere.  This would also allow someone to perhaps make a super short HDMI cable.

 

Here is what I am thinking:

LVDS I2S transmission is different from HDMI transmission, it just happens to use an HDMI cable.  LVDS !2S transmission is perfectly symmetrical differential signaling, and as such going to extreme short cable lengths is very unlikely to give any benefits.  I would advise that component placement should be prioritized over I2S cable lengths. You do not want your components so close together that the fields from their power supplies could couple with each other.

So, first, arrange your components such that they have reasonable distance from each other, then second choose the shortest I2S cable which works reasonably with this arrangement.  As to cable quality and using high end cables, some high end cables will indeed improve performance, but this will not be true across the board because all of these cables are engineered to make HDMI signaling improved, so some of them may have "features" which do not apply to the LVDS i2S signal.  I would emphasize two priorities when looking for the right LVDS i2S cable: first speed of transmission, and second equal propagation delay across all signal lines (keeping the balanced signal perfectly balanced), things like shielding (extremely important for HDMI due to the embedded nature of video and digital audio signals on the same cable) are not nearly as important for LVDS I2S.  In fact, an unshielded cable with better square wave response might be better in some system environments (shields add capacitance, which blurs square wave edges).

Bad idea, adapters will introduce much more signal distortion than a single normal length cable.  In almost every case, connectors are the weak point of any cable, adding additional connections its a bad idea.

You've shattered my dream of a 2" HDMI cable...

 Supra makes this in 0.5M and up actually... and what I use in my own setup. Check Ebay. Some resellers do not carry the shorter length for whatever reason. Just look around.

I use a Supra 0.5M HDMI cable too.  The "angled shell" isn't standard.  You can purchase it as an option and remove the standard "shell" and replace it with an angled kit.

That is what I worry most about my wonderful sounding (up til now) Nordost Silver Screen HDMI.  It's speed spec is nearly 7 years old, and although built very well, is shielded very well too.  Does anyone know if there is a ultra fast modern HDMi unshileded?

 

P.S  Searched for HD5 .5M on ebay, nothing so far.

Hey Ted, I doubt anyone would really make an unshielded HDMI cable (maybe Mapleshade?)  I just brought it up as an idea really.  Nordost has new, made in US high speed HDMI cables.  I have not tried them, but theoretically their construction should (monofilament wrap equalling mostly air dielectric) result in very fast propagation speeds and good square wave response.  If I was using LVDS/I2S I would experiment with those.

Is the better clock the only benefit of the SU-1 over the Spring's USB input?  If so, are we better off upgrading the USB clock?  @scan80269, you talked about removing the USB clock temporarily.  Do you plan to upgrade it, and perhaps compare it to your final modded SU-1?

The Spring DAC uses crystals, not oscillators, and has its own oscillation circuitry.  An effective upgrade of Spring clocks involves the use of replacement crystals with better performance than the stock crystals.  As hardly any crystal manufacturer provides phase noise plots with their products, it is impossible to guarantee any off-the-shelf crystals being superior to the stock ones.

 

What I did experimentally on my Spring was to remove one of the audio reference crystals, specifically the 22.5792MHz crystal used for 44.1/88.2/176.4/352.8K sampling rates.  This was only intended to determine how the Spring utilizes its internal audio clocks.  I did not mess with the Spring's USB clock (24MHz).  The two audio clocks (22.5792MHz and 24.576MHz) happen to be used by the Spring DAC only in conjunction with its USB input.

 

For Spring users, using a modified SU-1 to drive I2S (with very good clocks) into the Spring is a relatively straightforward upgrade over the Spring's USB input, without needing to modify the Spring itself.

I measured mine with the USB input, and given the pretty good results I would be interested to see some real world measurements as proof of external clocks actually improving the situation... ;)  At least I don't feel like having a pressing need to get one.

Are you talking about Holo Spring or SU-1?

Have you guys played around with different HDMI cables? I'm just using a really cheap generic HDMI cable I use for my DVD player and is wondering if it makes sense to invest in one of those short run cables from Kitsune.

I have tried 3 different ones including the $10 one from Kitsune.  I felt the Wireworld Ultraviolet sounded best.  I am now curious if moving up the chain a bit to the Starlight would improve things further.

Unfortunately I have not though I still want to.  I have just had more pressing priorities for my system.  I am hopeful I can refocus and try out the Starlight during this summer.
