I'm using the Sangean HDT-1X and it works well. Many tuners have noise which, ironically, is caused by the HD signal. The Sangean is so quiet it made me notice a low-level hum issue in my system which I had missed before. I've used the TOSLINK output into a Logitech Transporter with good results, but the analog output from the Sangean sounds quite similar. The format is not "CD Quality" as they claim but very quiet. HD stands for Hybrid Digital, not High Definition, but they keep that quiet! If you have reception problems or no way to access stations to your stereo by internet, it's a good choice. I'm using a full-size attic antenna but the reviews say the Sangean is very sensitive. See http://tech.groups.yahoo.com/group/FMtuners/ or http://www.fmtunerinfo.com/ for more.
