Audio Interface for DSP systems

I am just about to buy me a pair of 8250s.
My current setup with 8040s is completely analog, so I want to buy a new Audio Interface as well in order to have a fully digital setup, using AES/EBU to get audio to the loudspeakers. The problem is, I have a 27" iMac, so I can't use PCI-E soundcards, I have to buy either a USB or a Firewire soundcard - now you find AES/EBU ports only in the upper price section (RME for example hast it only in the Fireface UFX).
I don't mind spending more money for an audio interface, but I just want to be sure it's worth the penny.

Now I would be grateful for some help, I read through the threads here but I am still a bit confused..

1.) Will there be a difference in sound quality if I use a soundcard that has only S/PDIF outputs, putting a S/PDIF to AES/EBU converter after it or is it absolutely the same?

2.) Do audio interfaces vary in quality as far as the digital audio signal is concerned? I understand that Jitter affects sound quality and mostly occurs during the D/A-process, but can this happen within the digital chain as well?
Some people say there's no difference as long as the audio interface just delivers a digital signal and does not convert to analog.
Are there any recommendations for audio interfaces connected to a Genelec DSP system?

Thanks a lot!

Hi Philipp,

1. Please see this: viewtopic.php?f=4&t=59

2. I would say there is no clear audible difference.
