So I've been waiting patiently to purchase a new tuner. I have two component systems without FM radio right now, and I'm listening mostly to CD's/LP's. My thought was to wait for a decent HD radio tuner. I tried the Boston Acoustics HD tuner several months ago and walked away rather unimpressed. Besides, what I really want is a component to add to my system, and not a clock radio. So where is the technology now? Specifically, for those of you who have a tuner:

- What other tuner options are out there besides the Boston system? Are the components from Cambridge Audio & Rotel available with HD radio yet?

- What stations are available in the LA area?

- What is the sound quality really like? 64K-mp3? 128K-mp3? CD-quality? How does the sound compare to XM/Sirius?

- Do the sub-stations offer any content yet? If so, is it better/worse?

- Did you have to get a new or better antenna from what you were using for plain FM?

- Any other thoughts, recommendations?
