In Reply to: Any sound card for PC that does AES/EBU dgital out? posted by Triodeuser on October 8, 2006 at 20:58:25:
Keep in mind there is nothing particularly stellar about the Lynx's digital outputs (this card is designed primarily for mixing on the PC, which is why it has so many digital inputs, which is also why it costs so much).Here is a review that compared the digital outputs on the Lynx to a $99 card (they key part being "In digital output tests Juli@ is equal to LynxTwo.":
http://www.digit-life.com/articles2/esi-julia/index.htmlAlso, I've read that AES/EBU is just S/PDIF with a different connector, and that, often, the process used to support AES/EBU ends up being worse than just using S/PDIF via a coax connection (based on comments from the PS Audio site describing how most components implement AES/EBU output).
Follow Ups:
You are right about AES. Most manufacturers dont design it correctly and the impedance is usually wrong. I have to fix most of these. Some even connect the S/PDIF to the AES.
The review is amusing.First this seems to be a promotion for ESI; with $200 speakers used for testing $185 and $400 cards!
Second, there is a lot of techno spec for the ESI cards that is just wool over ones eyes; all card manufacturers claim magnificent performance.
Third, the RMAA tests are very suspect. We have s/n of 150 dB and dynamic range of 133 dB for all cards!! There is sonmething very wrong and when you compare RMAA results with real and proper measurement results, the former does not add up. Do a web search as to why.
I would urge people not to judge hardware on the basis of this sort of publicity.
Publicity? This is well-known, independent web site. I guess their earlier review of the LynxTwo is just shameless publicity for the greedy developers at Lynx?
http://www.digit-life.com/articles2/lynxtwo/index.htmlCan you point us to a comparison between the digital outputs of the Lynx and other sounds cards that you think is better?
Basically the review is rubbish, from the electronics and acoustics viewpoints. It is just marketing hype and illustrates how naive some pc audio testers are.If you believe this review, you will believe that the sound cards tested were immersed in liquid nitrogen to get -150dB signal to noise ratio.
Again, please point us to a review of the Lynx that meets your standards. Nothing is as worthless as criticism without reference.
I have tried to explain to you the lack of science in the review. If you cannot accept this, there is no motre I can do. Sorry but end of any further on this.
