Cool, curious minds want to know.

I'm thinking of getting Jkeny's very special USB cable and sell my Oyaide DB-510.
 


I saw a guy using the modded HiFace with this type of connector in his system and has was pretty happy with it.  I've never tried it but it seems that a short signal is a possible way to go for.

 

Is your DB-510 the BNC cable?  Why do you want to buy the USB cable?  According to Jkeny, the improvement will not be very big as 95% of the improvement has already be done.

DB-510 (BNC connectors)

DR-510 (RCA connectors)

I have the one with BNC connectors (DB-510) and I want to sell it to save big bucks on future upgrades. I read somewhere in the forum that USB cables especially with async transports and modded to seperate the AC from the data is less detrimental to SQ than coaxial cables.

If that is the case, I'd like to save some money and obtain better SQ by plugging the modded HiFace directly to my DAC with some sort of BNC male to BNC male adapter and use jkeny's very special USB cable as the extension.

 

Does that sound like a good idea? I'm open to comments, better ideas and suggestions.

I never said my batteries were better than any other LiFePO4 batteries - I just wanted to correct your mistaken view that every LiFePO4 battery comes from one manufacturer which is a nonsense.

 

Once you recognise this you will be better able to begin to test which battery you prefer because believe me they are not all the same.

 

I also told you that you will find a range of battery tests on RC forums which use them extensively.

Hey,Jkeny!

 

Which do you think is less detrimental to SQ with the Hiface?

A USB cable or a coax cable?

post #1446 of 1712

I've been off-air for a while.

 

My take on all this is that the digital cable would seem to be more important sonically than the USB cable. Obtaining the best SPDIF signal quality is important to sonics & this is best achieved by avoiding or minimising the effect of signal reflections. I went through a debate with Dan Lavry on this & I finally came down on his side in the argument over short versus long SPDIF cables. I believe a good quality back to back BNC adaptor of the sort mentioned here will probably be the best solution as it should provide a true 75 ohm impedance in as short a connection as possible thus minimising reflections & their effects.

 

This is not something that the cable vendors are going to want to hear (or will probably admit to) but from my level of technical knowledge at the moment, I believe this is the best solution.

 

Long SPDIF cables will also work but there are more variables to get right in this scenario.

 

slim.a, remind me again of the details, did you use a 5V supply on my modded USB cable & found no advantage to this configuration versus a stock extension cable with the 5V power coming from the PC? I always said that this was a 5% improvement (if that) & was dependent on the quality of the PC PS Vs the quality of the external 5V supply used. Can you give some details of both sides of this equation in your set-up?

Ok my flashlight gurus are wrong,  but I'm just doing a cheap mod and shared my info.  I suspect in about 12 months there will be chines USB transports with all the construction we desire for cheap.

 

Also I believe there is a burn in period for this stock Hiface,  it doesn't seem as harsh as it was,  anyone else notice a burn-in period (I'm a recoveryingt non believer in burn in.)

just wonder I am using Canare 75ohm cable. Can I know the best length (with the canare bnc plug)

As short as possible for SQ.

post #1450 of 1712

How short is short, is it can I start with 150mm or 300mm or even 50mm long. What I am trying to do is hear out the short canare BNC cable first before investing in other cables such as stereovox or black cat.

Surely physical limitations must dictate to you what is the shortest cable you can use? Go with that! 

post #1452 of 1712

to make it short, someone has posted this before and even in so other usb-spdif product. It is cheap and costs 6 USD. The specs is its VSWR is 17.7 dB with brass and nickel plating and gold contact.

 

wonder if this is good ?

I just picked up a male to male BNC adapter from ebay for less than $2 lol, I'm going to try this out when it gets here with a generic USB extension cable (as short as possible of course) - it makes sense to me to just remove the Coaxial cable all together if you can.

It makes incredible sense to me too. Which adapter is that and is it 100% 75ohms?

I'll try and ask some DIYer if he can swap the female BNC for a male one instead but I have to find someone who can do it for a reasonable price.

Oh really? Well that's just too bad for them! They can get out of the snake oil business and start engineering better stuff instead! I've had it with pricey S/PDIF cables!

I hope this is the best solution and I'll be able to put my money on better cans and better hardware. Cables are eating too much of my budget.
