USB to SPDIF converters shoot-out : EMU 0404 USB vs. Musiland Monitor 01 USD vs. Teralink-x vs. M2Tech hiFace - Page 109  

post #1621 of 1712

The DIY discussion for the last few pages is like watching sharks attack each other.

post #1622 of 1712

Should I get the 6 and 10DB units together to try out or ignore the 6dB as recommended by JosephK

post #1623 of 1712

I agree, I began to read the posts and tried to concentrate and understand but I ended to be bored. You guys should go PM if you want to draw your artillery and fight each others rather than doing it here. Along with advanced technical DIY stuff which is, even if interesting for the guys who want to dig deeply the tech aspects of the HiFace mods, all that should be explored in another thread where all the technical aspects could be discussed in the long way.

Reading some posts of impressions and projects, then a load of pages of bickering plus advanced technical stuff is a bit rude for folks who are not familiar with that and didn't came to find this kind of feed back and information. I mean this is not the purpose of the thread. If the discussion is opened to evolution then why not talking about silver, then silver factories, then working conditions in these, then politics...

Come on...

As long as tech speaking is not miles away it's ok, but please nothing like the last pages again.

Off-hand, I can not think of a source for the barrels, used in those devices. You could buy some, cannibalize some BNCs, and make your own. I used to work at a very large, yet extremely cheap, company, that thought it was better to make them in-house. No way you could buy the parts for much less than $14. Add to that the cost of labor. But for DIY, sure, why not.

 

If I can locate a source for the barrels, I will link it.

Ok thanks! That's pretty cool.

By the way Pacha, did you get a chance to directly A/B the Teralink X vs. your Hiface?

post #1626 of 1712

All, I apologise for my participation in these post over the last number of pages but I felt I had to respond to ad hominem attacks on me - I know it must have been annoying & boring for all here to have to read this & I'm sorry if my answering these posts prolonged the agony.

 

I seem to be under attack from a number of quarters so I felt the need to reply. I seem to be being accused of hoarding info & selling surreptitiously. As I have said before I have posted all the details & annotated pictures of how to do these mods for those that want to do so themselves. And I have explained why I was holding back on posting the info about the attenuators.

 

Just to be clear I have no intention of selling these attenuators - I consider these an adjunct to the Hiface. I will post here any useful info that I have about them with the understanding that these are the results I have found & may not apply to your system.

 

That's all I can do. Please don't ask me if X attenuator will improve X DAC. Edit: remember, these attenuators only work with transports that are outputting SPDIF at a higher voltage. This means it will work on the STOCK Hiface but probably not on the Musiland - I don't remember it's output but I think it's low. Also, in my opinion this is a great way to somewhat ameliorate the unavoidable reflections on SPDIF lines.

 

EDIT: One other aspect - these attenuators may be a good way of  reducing the sonic penalty that using a BNC to RCA adaptor usually entails.

 

I have posted the link to the cheapest place I have found on the internet for these attenuators at $12 each - there are other places that will charge you $30 for eactly the same thing - I've even seen them for >€100 in RS which I thought must be a mistake!

 

I think this is cheap enough to allow experimenting yourself with the range of these. http://www.minicircuits.com/products/attenuators_coax_fixed.html Scroll down to the bottom of the page - it's the BNC 75ohm variety that you want. They come in 3, 6, 10, 15, 20dB versions - the 3 & 20dB ones could probably be ruled out as too low & too high an attenuation. As I said what we seem to want to aim for is enough attenuation to suppress signal reflections BUT not too much to reduce the signal voltage too low.

 

I will ask the other tester that I mentioned earlier to post here his impressions & his system so as you get another opinion. I bought the 10, 15 & 20 versions & had them delivered to his US address. I'll let him say what he found but there was a combination of them that stopped the DAC locking to the SPDIF signal - I'm not sure if it was 15dB on one end of the cable & 20dB on the other end?

 

Hope this helps & adds to the general knowledge base?

 

If you find my presence here detrimental, I will remove myself from the thread as I had done already before the personal attacks started.

I'm not posting this here to restart the whole thing again & I won't respond to an attack for the sake of the sanity of the majority of readers here.

anyway, I hope you would continue posting. without your info, certainly we wuld not have known such situation exists, earlier or later.

Thanks for sharing, jkeny, I hope you continue to post.

I did not start the conversations, I was merely mentioning that threads sometimes change and then change back especially when they are large threads.

I can try and start another thread to be a positive forum member but that is not to say anybody will bother posting there instead of here.
 

Edit,

Here is another thread for ideas and theory related to the last few pages, if anybody is interested in keeping with the flow-> LINK

Thanks for the link of the thread. It was indeed an excellent subject that needed a separate thread. I just posted a reply there.

I quickly compared the modded HiFace in KS to the Teralink-X in A4A with the RCA/RCA male adapter with each one, not yet with the Oyaide. Things has gotten better, but I need more testing though. Maybe the FUN isn't revealing all the differences that could be heard. The usb extension cable I'm using is also brand new. Anyway, more airiness, a bit better bass regarding bass definition, and larger soundstage, and I don't hear as much the sibilance and treble peak as with the Teralink-X with the T1, I'm almost done with it, it's way better now.

I don't know if there is some kind of burn-in to the mod also, I guess there shouldn't be as the HiFace was already burned-in and the new components mayn't be prone to burn-in effects on the sound. I will give more input later but I'm a bit running out of time at the moment. Maybe we could also quickly compare both on the DAC19DSP/C2 on monday so that I see how they sound like on another setup? Did you tried to compare them on both the FUN and the DAC19 before by the way?

Personally, I have found that moving from the Teralink X to the modified hiface affected the FUN and the DAC19 in 2 different ways:

- I would rate the Teralink X + FUN as bad while the modified Hiface + FUN as good

- I would rate the Teralink X + dac19 as very good and the modified Hiface + dac19 as excellent

 

While the change in the FUN might be smaller in scale, it prevents it from sounding bad (to my ears).

But I have to admit, that since I got the Teralink X2, I rarely listened to the X1 (except when I was writing the modified hiface review). As for the X2, I only use it when I forget to recharge my modified hiface.

 

Regarding the "burn-in", I noticed an improvement after the first cycle of use (discharge/recharge). But it was small enough that I suspected that my ears were being burned-in and not the component ... Some people have noticed burn-in with the stock hiface while I didn't notice a big difference. At the same time I found that both the Teralink X and X2 changed significantly during the first few days.

post #1633 of 1712

I must say that the Teralink-X with the FUN don't sound very good. But also I never got used to it after having tried the DAC19DSP/C2 with modded HiFace at your place since the last time, everything sounded totally anemic after having listened to your setup. I have no interest in buying the DAC19DSP/C2 right now as I'm leaving soon until mid august but as soon as I come back I will place an order on the couple, listening to the FUN is such a pain when you know how the DAC19DSP/C2 sound.

Hopefully we won't torture ourselves in the same way if we could listen to the Ref1 with Phoenix, as it is hard to find. Good thing for our wallets, at least for the near future

@slim.a

 

Just to be clear, your talking about jkeny's HiFace and not a stock model.

 

USG

post #1635 of 1712

Eh? He made it very clear - "modified Hiface". Besides, it's not going to take much to find out only jkeny does the mods, at least for now. Not sure if you're affiliated with jkeny by any chance? lol
