Topping has a long reputation for decent reliability, but it's extremely popular, so you might find a few complaints. SMSL? I'd avoid them. Other, new Chinese brands that almost no one has heard of? I'd be wary. There is a lot of cheap stuff out there. I have two Indeed t-amps (ebay only sales). That's a good brand for t-amps.
One way to learn more about good t-amp brands is to research in the DIYaudio
community. They examine the electronics and have a good idea of which brands are using good stuff (that's where I found out about Indeed)
