Grace has discontinued that tuner but the Grace Mondo+ looks like an interesting alternative. It's not exactly a component tuner, more like an Internet radio, but it has RCA jacks to connect to an amp.
The problem with the standalone Internet tuners and Internet radios is they all lack support for at least one streaming service or another. The Mondo+ is about the most full-featured one I've seen with native support for a whole bunch of services, plus Chromecast and Bluetooth which provide workarounds for getting to the services that aren't natively supported.
Using a laptop lets you punch up any station or aggregator you want, though. And you can easily use a VPN on a real computer to connect to servers in countries where the stations you want to hear are geographically restricted (CBC Music in Canada, for example). Bluetooth digitally compresses the audio so there is some degradation in sound quality but the codec is pretty good so you may not be able to tell. You could always connect the headphone output of the laptop directly to the amp and see if you can hear the difference.
Speaking of CBC Music, there's another workaround that doesn't require VPN outside of Canada if you own an Amazon Echo device. You can say, "Alexa, ask CBC to play CBC Music," which invokes the CBC skill bypassing the geographic restriction. You can always plug an Amazon Dot, Amazon Input or the pricey Echo Link into your amp and use that to stream music too.
There's just a ton of different ways to do this now, and it seems like more devices are coming out all the time.
