Anthem STR preamp vs Integrated amp preamp section


Hi all, I'm having trouble really finding good info about this.

I currently have the Anthem STR Integrated Preamp.  But wondering if I should sell it and just get the STR preamp and use my PS Audio m700 amps.

My main question is, what are the main differences in the preamp sections?  Different dac?  Different processing?

I'm not totally comfortable understanding everything on their spec sheets.

Thanks

I agree, it should, I hope it does, but I can't be the first person to want to connect an iPhone/iPod/iPad. Odd getting a clear answer has been a challenge. I guess I'll know when I get my STR preamp in a week or so.

I just don't want to have multiple DA/AD/DA conversions.

Thanks.
I think the consensus would be that streaming anything straight from your iphone would be considered an inferior source in the first place.  If you can afford an Anthem STR product, why wouldn't you get a dedicated streamer like the Bluesound Node 2i or something?  
@dtximages, I have no interest in streaming?  I want a direct digital connection  via lightning to USB to the STR DAC.

Are you asking me a question?  You want a direct connection from your iPhone to your Anthem STR?
Op, did you ever end up making the switch? I'm sort of in a similar dilemma and I would love to hear if you noticed any sonic differences after you made the switch. 

Best,
