Default Class D amp recommendation

Hi,

I am interested in getting a high quality class D amp. Played around with tripath stuff before.

What I am looking for is 20-50W of power. Maybe TPA3116 or 3118 or 3250. Good quality caps. Torrodial type inductors for the output. Possibly something like this, which features WIMA cap. No input buffer, do not wish to add an additional stage. Budget of <USD 200.

SG$ 23.13 32%OFF | AIYIMA Professional Mini Amplificador Audio Amplifiers Board TPA3116 2.0 Dual Chip Digital Power Amplifier 100W For Home Theater
AIYIMA Professional Mini Amplificador Audio Amplifiers Board TPA3116 2.0 Dual Chip Digital Power Amplifier 100W For Home Theater-in Amplifier from Consumer Electronics on Aliexpress.com | Alibaba Group

Thanking all in advance

Oon

This, if you want something to plug in and go:

Volt+ D (Double) 2x60W

Or this, if you are happy to source your own case, volume control etc and connect it all up:

TPA3251 2x140W 2Ch Class D Audio Amplifier | eBay

Yeah. I was looking everywhere for it. I wonder why?

Suppose to be a cut above the 3116 or 3118
