As the replies state, no HDD/flash memory to rip audio files to. I know the following solution is a hassle but let's face it, CD's are dead! I specifically had to order my Summit (Dec delivery) to NOT get the CD unit. Too bad your dealer boned you on that one.
No auto ripping HDD is actually a very good thing especially since you have the awesome surround sound Harmon Kardon system. Here's why. That stereo is so friggin' good that it exposes the HUGE quality differences between audio CD's (60-100MB per song) and .MP3 files (2-14MB per song). First, any HDD would be outdated (ie undersized) the second it is installed. Second, the software ripper the mfr would use would almost assuredly not maximize sound quality as it rips to the HDD and the playback would be noticeably inferior to the original CD. Sooo, what I am in the process of doing is ripping my 400 CD's to .MP3 files using the highest quality free ripper I could find tuned to the highest quality output. I have tested the output and it's pretty darned good. Certainly blows away the playback quality of any .MP3 file I have ever heard or downloaded. It's pretty fast too. I can rip 30 CD's in about 45 minutes counting all the in/out/create directory, etc... stuff. I have chosen to place them all on a high speed (Class 10) 64GB SD card. Should fill about 50GB.
The download can be found here:
It's totally free, no begging for donations (although I did when I used and loved it), no shareware, etc.....
If you or anyone else is interested I can give some tips on tuning it to max the quality. Also have some tips on output format after I tested the menu system on the 8.4AN.
