In Reply to: RE: Upsampling in cPlay posted by edward on October 18, 2009 at 14:48:05
Hi DeDe
Just to continue Edward's "it depends" answer... I run the output of cMP/cPlay from the Juli@ card via S/PDIF into a Benchmark DAC1. The DAC1 resamples ALL incoming datastreams to 110 KHz (this being the SR that the engineers feel is the sweet-spot of performance for the DAC chip they use). There is no user option to alter this behaviour - it's the internal architecture.
Curiously (or maybe not...) The change in upsampling with cPlay is readily apparent in my system, from no-upsampling, to 2x SR to 4x SR. Although the DAC1 converts it "down" to 110 KHz, I find setting cPlay to output at 192 KHz gives me the most pleasing (and seemingly accurate/ revealing sound).
Other's preference will certainly vary... so the "correct" way would be as Edward says - whatever you like best. Figure that out, and enjoy your music guilt-free !
That's not a Toy... IT'S A TOOL !!
I find this hard to understand. I too output to a dac1 digital aes3. the dac1 input is 24/96, how do you input at 192. When I output above 96 the dac does not input the signal, Lynx L22/Cplay advanced no power mods. T.
No worries!
@tsearay: I connect to DAC1 using S/PDIF. Though mine is original issue DAC1, it has been factory upgraded to full 192 KHz capability.
Does the Lynx22 send 192 KHz in single-wire AES mode, or dual-wire mode ? It must be single-wire AES for DAC1 to work at 192 KHz on XLR input.
Hope this helps.
Cheers,
Grant

AH. You dont output higher than 96k on the Lynx.The Juli@ though can do 192.
And have you tried the analog outs of your lynx? That WILL handle 192k.

What leads you to say this? My lynx aes shows an output setting of single wire 192 as well as dual wire 192. I have no way to test it presently, but it appears it is in its ken.
Yeah, for the AES, but we are talking about the L22.
Look at the spec sheet for the AES 16 it DOES have support for 192, but not the L22. Look under Digital I/O in the lynxs ( :) )below

and for the l22

Your right, I missed which Lynx you were talking about and hadn't realized they differed in this respect.
I wasn't sure myself!
Looks like the 16 came later and supports 192. Thats a great thing for those who have the cards.
Ah! Thank you! you are correct the digital out on the Lynx is limited to 96. I have tried the balanced out but prefer the digital to DAC. I have been struggling with "to upsample or not to upsample" to the dac, myself. I get a lower latency at 96 than 41 but really hard to tell if there is a benefit in SQ. AES/XLR throughput to balanced amplification. T.
No worries!
I thought it was worthy of a semi-celebration.
Heh-heh... Thank You Rick for the kind thought. Let us find a suitable container and pour a half-glass...
Cheers,
Grant
