In my restoration of 103.3 I read up quite a bit on the newer Chinese Amps and Preamps and dipped a toe in.

I bought Aiyma A07 Class D amp for $72 with 32V 5A psu. It does the job well and sounds clean but for the target of 50-200W at 4ohms it leaves some to be desired on the upper volume end. 2Ch at 4ohm is about 75W. My Yamaha RX-V2095 at 220W at 4ohm is in much greater control. Perhaps a 48V 7/10A PSU might do the KEF 103.3 more justice.

I also wanted a USB DAC and Preamp at Bought the Aiyima T8 Tube Preamp/Dac for $125. 3 Digital inputs, spdif, coaxial and USB, BT 50 apTX HD, and 1 analog line in.
My Kube set between amp and preamp. The Tube gives a good warm sound. I'm no purist and like the useability and functions it provides. It streams well from BT and USB PC.

Really interesting that these chip amps are coming into their own.

I myself have been driving my 105.4 with a Tripath-based amp, the Amptastic Mini-1. It's never going to give seismic bass but it actually works very well in most respcts!
