Lossless is better because it is just that, lossless. AAC 256kbps is compressed, where as lossless compresses it to the point where there is just all the needed data for untouched audio reproduction (from the standpoint of what was on the CD).

And the HD650 would not be ideal for portable ipod use and as you mentioned an amp, you would need one for sure

would an ipod dock + 1/8 to rca work? (theres a line out on the back of the dock)

I haven't played with AAC before, I usually use ogg or mp3 or ma or flac.

Here's an interesting take on AAC at 128 kbps..

Try 192 AAC VBR. I find that sounds as good as lossless at a fraction of the file size.

See ya

iPod can be a decent enough source if you use variable compression lossy format. VBR MP3 is quite OK

Best suggestion that I can make is to try a few different compressions and see which level you find acceptable.

I also support the line-out option ($20 is plenty good enough quality from Turbo etc, but not a store bought one).

I would suggest that for portable use, the AAC file is "better" because it will most likely sound indistinguishable to the lossless file at a fraction of the size.

a couple people have mentioned buying docks from 'turbo', what would be different form this dock and the apple ipod dock (that comes in the ipod box)

I've put together a very decent portable (around the house) rig: iPod 4G+Hornet M+HD600+ALO Cryo Dock. From my limited experience (I am not a techie) I understand, that the weakest link in my rig is AAC encoding and I've ripped a few good quality CDs in lossless just to see how it is. The difference in quality is there, however I am having a hard time justifying the file size. Is it, like 5mgb vs 25 mgb per song, if I am not mistaken? I listen to classical mostly and I will have to make a decision, whether it is wortwile to re-rip my collection in lossless (about 500 CDs). What is your perception of a difference in SQ, AAC vs lossless? Thanks.

The "turbo" dock, only uses the audio pins, all the other pins are by passed and in theory should give you a cleaner sound.

Unless you're listening to uncompressed wav files (which is completely pointless), they shouldn't be anything like that big. Three minutes odd in flac or alac should be about ten meg.

No-one else's perception matters - only yours. Personally I can't tell the difference between high-bitrate AAC and lossless, but how does that help you? Trust your own ears!

3 minutes in FLAC is more like 16megs on the low end, 25 megs on the high end. ALAC doesn't encode as efficiently either.


256kbps AAC for a portable iPod should be plenty sufficient. It's already very hard to tell the difference between the two with a nice source, let alone with a portable source.

 

[Dutchess of York]

Ok.....finished finding as many cds as possible, now converting to lossless

 

[n4k33n]

I just started hitting up the peer to peer networks for flac files.

 

[jaredy]

Agreed. An Ipod for the source doesn't necessitate the use of lossless unless you really want to. And, indeed, the size can greatly very depending on how the song needs it.
