Lucid or RME ADI

[frist44]

I currently have an RME multiset and I'm looking to add 2 channels of really good a/d conversion. The budget is about $1000. I woudln't mind picking up something like that ADI-pro or DS to use all 8 channels, but how would that setup compare with my current multiset along with a lucid AD9624.

So just based on the converter along, what do you think would sound better, the RME ADI-DS or the lucid AD924?

Thanks,
Brandon
