Need help upgrading/choosing 2.1 system for everyday use (Hypex NCore/IcePower?)

[lmaobrah]

Hi everyone,
I'm currently use 2.1 system for my everyday use in my living room (Games, YouTube, Movies, etc).
Current System
Using PC -> Borizonic Dac/Amp and TV (RCA) to the same Dac. (Link for Dac/Amp <<Link>>)
Dac/Amp to a pair of 6.5" Bookshelf Speakers and using Dac's Headphone out to an active Subwoofer.

Next step
I would like to upgrade the amp/dac, (preferably class D) for better sound quality. (keeping the budget under $700-$1000)
Reading about the Hypex Ncore/IcePower, seems like a good choice. But most of them is 2 channel power amp.
Not sure how to integrate the Sub without sacrificing much sound quality.

So my possible choices are:
1. FxAudio X6 Dac (Or other dac) ---> Hypex Ncore 252 Amp (Using RCA splitter for Subwoofer) ($700) Still not sure how to connect the TV.
2. Aiyima Preamp Dac <<Link>> ---> Hypex Ncore 252 Amp (Using RCA splitter for Subwoofer) ($750) Aiyima is with aux/rca in so I can also connect TV, but I don't prefer tube though.
3. SMSL A8 (Icepower) Using Dac out for sub woofer ($600) Easiest one stop solution
4. Dac ---> NAD C368 ($900) NAD offers massive connection

Or any other better choice, please recommend. Thanks very much!

What's the wattage required? Does the subwoofer have it's own crossover? Do you run the 2-way speakers full range or do you trim out the excess bass? How efficient are the speakers, and what is the placement in the room like?

- Wattage required
My current speakers are 87db, and my current 100W@4Ohm Class D amp seems to be enough.

- Sub Woofer
Yes, active subwoofer is with it's own crossover

- Speakers
It's bookshelf speaker, placing 1.6Meters from each other and around 1.8m from listening spot (Sofa).
The speakers run full-range.

Nad C368 is my personal suggestion. If money is the issue I suggest these folks: https://www.safeandsoundhq.com

I've bought from them in the past. They currently have a refurbished unit at around $600.

Have you considered the WXA-50 Yamaha, the power into 4 ohms is close to the per you have now. I compared it to the NAD D3020 V2, and I liked it better however not by a huge margin. The NAD sounded good also.
