I can select Internet radio stations from anywhere in the world and the sound quality is very good. Internet stations can be selected by country or music type (classical, blues, jazz, new ages, etc).
My Internet media tuner (MD807t) allows me to create and organize my favorite list of stations via an Internet Radio Portal website. This feature allows me to have a full list of the stations I listen to regularly on one page instead of having to search each time. Some stations come in sounding better than other stations. I try to select Internet stations that are using 128k or higher. Stations using lower numbers (such as 48k, 64k, etc) do not sound as good.
As per Magnum Dynalab instructions, I setup the Frontier Silicon radio portal for this capability. It is free and very easy to use. The portal provides an excellent search capability to help you identify the Internet stations you want to listen to. You build your list on the computer and select the stations you want to listen to on your Internet tuner. This is an excellent feature and makes the Internet radio selection process much easier. New stations can be easily added or deleted using the Frontier Silicon radio portal. See www.wifiradio-frontier
Linn Classical has an Internet station I like very much.
