AV setup with LS50

I just bought a pair of LS50 and need some help with finding a nice but good value home theatre setup. As I am based in Japan, I have easy access to Japanese amps, etc. I will be using it in a small apartment, in a 2 channel setup. Source will be PC and TV.

How does the following options look?
Marantz NR1609:http://us.marantz.com/us/Products/Pages/ProductDetails.aspx?CatId=avreceivers&ProductId=NR1609
Number of Poweramps 7
Power Output (8 ohm, 20 Hz - 20 kHz, 0.08% 2ch Drive) 50 W
Power Output (8 ohm, 20 Hz - 20 kHz, 0.05% 2ch Drive)
Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive)70 WPower Output (6 ohm, 1 kHz, 10% 1ch Drive)100 W

Onkyo TX-NR686 https://www.onkyousa.com/Products/model.php?m=TX-NR686&class=Receiver&source=prodClass
240 W (3 Ohms, Front)
210 W (4 Ohms, Front)
120 W (8 Ohms, Front)

Yamaha RX-A880
https://jp.yamaha.com/products/audio_visual/av_receivers_amps/rx-a880/specs.html#product-tabs
20Hz-20kHz、2ch: 100W/ch（6Ω、0.06％THD）

Open to suggestions/feedbacks thanks.

Thanks for the feedback AJ.

To give more information, the apartment is only 40square meters, and the lounge area where this is used is around 15 square meters. For now I will only be using it in a 2 channel setup, though this may change later on if I see a need to upgrade to 5 channel (or if I move to a bigger place)

Any thoughts on the Onkyo TX NR686? It claims to do 100W per channel in a 2 channel setup.

All Channels:
100 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven, FTC)
210 W/Ch (6 Ohms, 1 kHz, 10% THD, 1 Channel Driven)

Dynamic power:
240 W (3 Ohms, Front)
210 W (4 Ohms, Front)
120 W (8 Ohms, Front)

AJ, Thanks for your comments. It does make sense that if I just need something to power the speakers for now, all I need is a solid 2 channel amplifier, without all the bells and whistles of a cinema AV box. I will take a closer look at this area. A quick check of the Marantz PM8005 shows it is "Rated at 70 watts per channel into 8 ohms, the PM8005 features a robust power supply along with high current capability to deliver 100 watts per channel into 4 ohms" 70W per channel at 8Ohm sounds a bit low?

The Yamaha A-S801 looks interesting:
Standard: 100W+100W/8Ω（20Hz～20kHz、0.019％THD）、120W+120W/6Ω （20Hz～20kHz、0.038％THD）

Dynamic power（IHF）140W/8Ω、170W/6Ω、220W/4Ω、290W/2Ω

Rotel has 2 products that has the power to drive the LS50 - 1570 & 1582
http://www.rotel.co.jp/products.html
Seems to be about $2k USD.

Came across this interesting article and it looks like the Rotel A10 is a very good pairing amp for the LS50:
https://darko.audio/2017/07/happy-accidents-will-happen-rotels-ra-10-integrated-amplifier/
The reviewer recommends a combination of Aries Mini + Rotel RA-10.
How would it work if I need to have multiple sources, like PC, TV?

Went to the shop and demo'd the Yamaha A-S801 and Marantz PM8006 amp on the LS50 The sound from the Marantz amp had more bass and seemed smoother than the Yamaha. Would have loved to listen to the Rotel RA-10 as well, but this model is not sold in Japan. Price of the Marantz is higher than I would have liked but this sounds the best from what I have heard on the LS50 so far.

On the DAC side of things, I did more research on the weekend and the Raspberry Pi based Allo Katana DAC just got released recently with the latest chipset looks to be the one to get.
