Topic: V3 vs 722/44 A/D (comments from SD)

[trajhip2000]

here are some comments from the SD folks on the A/D chip in the V3 vs the 722/744T, taken from the SD support forum. Of course, the A/D chip itself is only part of the story, implementation has a lot to do with how things eventually sound, but I thought it was interesting:

>The V3 uses a PCM1804 from TI, and the 744 uses a CS5361. As a side note - we started this design with the 1804, but it turned out to be such a poor chip in almost every regard, we sold them all back to TI and switched to the much better, cleaner 5361. It is quieter, lower distortion, lower group delay, draws less current, has MUCH better anti-aliasing at higher sample rates, and has no idle tones, and most importantly, sounds much better.<

FWIW.

So why dont they use the new chip in the v3 or are they.

[MattD]

Said chip may not have existed when the V3 was designed.

mytek uses the CS5396 in their x96 products.  not sure which one in the stereo192

[wboswell]

now there's undisputable proof it sounds better!

[scb]

the stereo192 might use the 5381, which seems to be a 61 with better specs

now there's undisputable proof it sounds better!

I'm sure bean will agree 

[F.O.Bean]

I'm sure bean will agree

 

[JackoRoses]

so who is going to mod the v3 with this newer chip and report the results back?

+T for saying exactly what I was thinking.

Only when run akg's are involved

Sounds like this could just be SD fluff?

huh?  they are telling why what chip they used and why....you would be lucky to have most companies give you the manufacturer of the chip they use much less the model.....at the most it is insight into how they designed the product...

I think this is the part that would be the fluff:

and most importantly, sounds much better.<

isnt that a given though...what are they going to do, develop a product, say why thy use a specific chip, and then say it sounds like shit?...thats not fluff, thats called advertising
