Everyone in here makes resampling sound like some horrible thing
It is a bad thing...we all want to maintain the lineage of the original recording...hence why we use lossless compression programs, dont like MP3s, etc. Resampling has an effect on the signal that is not necessary, which is why it is avoided.
If you're paying $2000 more for the SD pre, I'm sure you can score something better for that price.
First, dont be so sure...there is a reason why everyone owns different rigs, because not everyone hears things the same. As for the $2000 more for the pre...no, I am paying the price for the 722 because (1) I want to get to a one box setup that is competitive with multi box setups and sounds fantastic to me, (2) sound devices has always been absolutely fantastic at product support and customer service to me...only Grace Designs and Oade are in that same league, (3) the box is in the field...the glitches are being fixed as identified and you can hear what it sounds like...unlike the R4, and (4) the SD box is well made, it is a metal enclosure, made for durability...though I have not seen the R4, I have heard it is plastic and as a result I have concerns over field durability.
Now this is not to say that the R4 will not be a solid box...it very well might be...or maybe another competitor will step in with a good box...oh yeah, the price for the 722 is sub $2500....and only speaking for myself, it replaced multiple boxes in my chain, and thus the cost was a wash in terms of $$ investment and the ability to get to a much smaller profile rig...but that is just me....ymmv
