Deh-p800prs

Not that most care about it, but it also now supports the bluetooth and HD add-ons. The 880 didn't.

Yea I couldn't give two sh*ts about HD radio and BT.

I can't believe they include those two in a SQ-oriented head unit and not USB built-in... ugh.

USB isn't really SQ.

USB isn't really SQ.

With portable, USB-powered hard drives now reaching 320GB, you can compile your ENTIRE collection of CD's onto one hard drive as .wav's (lossless) and still take full advantage of all the processing and the DAC's.

Also, with 320Kbps MP3's ripped from my CD's, I hardly notice any difference at all as long as the original recording isn't extensively clipped. The USB input can be just as much SQ oriented as the CD-ROM.

So in short, USB can be SQ.

Talk about being out of the loop. I've been working out of state and haven't had internet access until this week and am seeing the 800prs for the first time. I must say that it is the sexiest head unit Pioneer has put out in the USA since the P9.

Very nicely done Pioneer.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

From a purist point of view the CD is superior. Mp3s are compressed and therefore inferior to CD. However, with a good rip in mp3 VBR you wouldn't notice much difference while driving down the road with background noise.

Could you guys please read what I say! lol... You can use an HDD to store 320GB's of .wav's (lossless) and play them through your head unit. You aren't restricted to MP3's and you can consolidate your entire CD collection to a hard drive.

Yes, but how is it interfaced with the deck? Probably with a cable. With a CD played right in the deck the signal can't be degraded by that. I know that is nitpicky but it is still true.

But yes, the idea of having than much music in high quality wave format does sound great.

Haha, yea you REALLY have to be picky to care about that lol...

But I see what you're saying.

I seriously doubt the SQ experience you could create within your vehicle would degrade due to digital data traveling over a short USB cable compaired to straight off a laser. It's pretty hard to cause interference to degrade data transmission.

Also, I don't believe it is transmitting the 'quality' of the audio. It is purely transmitting data (probably with a checksum or some form of data integrity check) that the head unit processes to create the 'quality'.

I really want this deck to hit the shelves soon looks to be my new deck.

Hey guys, since the data is transfered digitally from the hard drive, there would be no degradation from any length of USB cable. Actually, you'd benefit because it would be impossible for it to skip. Also, computer cd readers tend to have better error correction algorithms and so theoretically the wav file could be better than reading it directly from the cd via the deck. Of course, this is all theory... nobody would actually be able to tell the difference in an audio test.

Good point. I guess I was thinking more of someone running analog but that surely wouldn't be the case.

in fact CD-ROM drives do not have an error correction especially for audio cds, they only try to correct the bits itself e.g. using the CRC checksum.

audio-cd-players have an built in error correction for wav. that is how some copy protected CDs work, they have errors on it an audio-cd-drive corrects without much thinking, your computer cd-drive gives you an error because the cd seems to be damaged.

but nevertheless all new decks that can play MP3 do not have an audio-cd-drive and therefore do no more have this error correction. that is y some SQ-decks do not support mp3, like the clarion 9255 or pioneer P90.

but a good computer-drive is as good as an audio-drive as long as the CD is not badly scratched and damaged.

but with USB beeing a digital connection its better to have full-speed-ipod-interfaces, so that the D/A convertion takes place in the HU, not in the crappy ipod D/A converter.

Well if any of you were wondering the 800 PRS faceplate will work on an 880 unit.

Oh ya? You have both?
