Beginner Looking For Set Up Advice!

Hi Everyone, thanks again for the help! This has been fun and informative.  

I've narrowed down to these options, in no particular order: 
Peachtree 125 SKY $600
Yamaha S301/S501 + Bluesound Node $1k - $1,250
Marantz PM7007 $1k 

I like the idea of separates, but couple questions:
1. With the Yamaha/Node setup, the sound when playing movies/tv etc won't be as good as the other two setups as they won't be taking advantage of the Bluesound DAC, correct?
2. Would there be any major difference between the S301 & S501 for me? Apartment living room is roughly 400sqft

Personally, I can’t recommend the Yamaha. It was my dissatisfaction with my Yamaha integrated that led to my latest foray into hi fi gear. Can’t imagine their entry level stuff is any better. As far as an external streaming solution goes, have you looked into the RPi stuff? Reviews are good and very budget friendly.

btw... not trying to be THAT guy, but...“separates” refers to separate preamplifier/power amplifier.

Your going to be driving the tv sound through whatever 2ch set up you decide on, the streamer will have no bearing. To clarify what I mentioned earlier, IF you have a separate streaming device(Node2i) connected to an integrated such as the ones your looking at, you always have the option to use the Node dac via analog, the integrated dac via ditigal out from Node OR to put a DAC of your choice between them and utilize the integrated as an amp only. IE flexibility. I do this with a Peachtree Nova 300/Node2i system with any of the dacs I have on the shelf for a change if I choose. That’s what I meant by separate.
If any of the three choices you mentioned has an trial period, or large return window, make a choice, order, listen and if you don’t like the results send it back within the time window and try the next one.
The Yamahas are essentially the same with the 501 having better connectors and 25 wpc more than the 301

I am a little concerned about the power requirement given your speakers and room size. I could be wrong depending on loudness levels desired. If going with the Yamaha line I would consider the 701 or 801(USB needs?). One can stream via iphone or computer via USB.

Do you currently have a CD or LP collection? How about the TT or CD player? It would be good to know more as to where you might go here.

One thing going for the Peachtree  unit is that it can be used as a stand alone or as a preamp (having preamp outputs)  allowing for the use of a separate amplifier if one find more power is needed. Seems like a good deal at the reduced price. I would look further into streaming devices that could work with it.  

Thanks - still haven’t made any final decision - I don’t have a large cd collection and doubt it will ever grow just due to the emergence of lossless streaming. 
Would the Yamaha/marantz or something similar sound better than the peachtree as they’re class AB rather than D or is it just a different sound? In terms of power I’m hearing different things so not exactly sure what I need. 
I’m sure all the choices will sound great so looking to make a decision this week. Thanks!
