Hi Jambro,
Nice digital setup!
You may want to check if the Lynx is capable of the 2-wire AES/EBU format. I think the dCS Elgar do not accept a single wire AES/EBU format above 24/96. They only do 2-wire for 24/176.4 and 192. If the Lynx can output in 2-wire format , then you'll have to set that up accordingly. The dCS manual provide info on which channel, 1 or 2, (A or B), is left and which is right,
I did consider using Lynx and a few other pro-audio format conversion options, but I decided on using the Weiss DACs because they accept a direct Firewire out from the PC and have single wire capability up to 24/176.4 and 192. Simpler, cleaner interface and the processing is done outside of the noisy PC environment.
But, whichever hardware you use, I think the PC OS is still not very simple or friendly yet. I think you may have to fiddle with the control panel settings, Media Monkey settings, Lynx settings, etc for the 24/176.4 to be seen at the Elgar.... I'm still learning myself! But, when I got it right, the sound is quite an experience!
Regards,
