Default Stepping up from the TPA3116 - amplifier recommendations to fit my new chassis?

Hi all

It has been a while since I modded/built an amplifier so I'm out of the loop. Could I have some recommendations please?
I have the following chassis:
Single large VU amplifier chassis
New Aluminum VU meter amplifier Enclosure chassis case/amp box for DIY YA53 | eBay
Internal dimensions:
Width = 210mm
Height = 83 mm
Depth = 295mm

I wish to keep everything within the chassis (however would entertain using a large external laptop brick etc) and the sound quality should be as good as TPA3116 however more powerful. I'm not looking to spend silly amounts and am a fan of the class D amps and cheap boards.
My speakers are usually 6-8 ohms.

What chip/board would you suggest?

Also; the chassis has two rotary dials on the front and would like at least remote on/off volume and input selection. I have seen these on ebay but no reviews:
9V Infrared Remote Control Volume Control Board ALPS Pre AMP Motor Potentiometer
9V Infrared Remote Control Volume Control Board ALPS Pre AMP Motor Potentiometer | eBay

4 Way Input Source Selector For Audio Preamp Amplifier DIY Kit / 4 In 1 Out
4 Way Input Source Selector For Audio Preamp Amplifier DIY Kit / 4 In 1 Out | eBay

or an all in one version:
Remote ALPS motor Volume control preamplifier board + Standby board R112
Remote ALPS motor Volume control preamplifier board + Standby board R112 | eBay

TDA7498 or TAS5630 spring to mind.
