Title: Do you have an iPod Classic?
Post by: Antigen on 2012-06-17 21:15:05
Hi,

my question is very simple, do you have an iPod classic? Do you use with an HIFI?

And the most important question:

- what is the audio format that you use with it? MP3 by LAME? AAC by iTunes (Plus)? Or another formats?

Actually I think that I will but an iPod classic, but I will continue to use with MP3 LAME, i'm not convicend from Apple to use iTunes to rip my CD, I have heard diferent versione, but all tell me that AAC from iTunes are not of high quality, and is better MP3 by Lame


Thanks!

Have you verified this subjective impression about sound quality using a double-blind ABX test? If not, it is in violation of #8 of the terms of service (http://www.hydrogenaudio.org/forums/index.php?showtopic=3974) and is unwelcome here, not to mention completely useless.

I’d have asked if perhaps you instead meant, by “all tell me”, that people on other sites have told you that AAC is bad – in which case I’d advise you to stop forming cemented impressions based upon the first thing you ‘hear’ about any given topic, especially if woo-preventing measures such as TOS #8 are not in place – but I know that you recently asked here which was better of 256 kbps AAC and 320 kbps MP3, and were no doubt assured at least once that both are likely to be perceptually equivalent but that AAC is technically more able, in theory, to provide transparency at any given identical bitrate (which only begins to matter as the rate decreases).

So, why are you doubtful?

Wait!

I don't comment the quality of an AAC vs MP3.

I know, by hearing test that an AAC made from iTunes is different from a Nero AAC encoder, and for this the quality is better that i Tunes.

My doubt about iTunes AAC or Nero AAC is simple:

- is less compatibile

My Car Stereo don't read it for example and I think that is not a good idea link an iPod to the AUX IN, the battery of the player at "high volume" will be fried in some month.

I'm only curios to know what users use for RIP their CD audio for the iPod Classic, only this.

That’s funny, because I don’t see any mention in your previous post about Nero’s encoder: rather, this seems like a failed attempt at shifting the goalposts, which instead simply transposes your invalid subjective comparison from AAC vs. MP3 to iTunes AAC vs. Nero AAC.

Regardless of the specifics, yet again: Unless you have objective evidence for your claimed detection of a difference in quality, it’s not wanted on Hydrogenaudio.

For Apple (and everything else) I use dbPowerAMP CD ripper (FLAC) and encode to AAC (.m4a) using Nero AAC encoder and dbPowerAMP Music Converter. Then I use iTunes to sync the music to the Apple device.

Works good for me.

I use only Nero AAC in last two years, because I mostly listen music on iPod Touch. Ripping it with either EAC or CueRipper... and encoding to v0.43, which gives me roughly 140-something bitrate. Enough for me.

This is nonsense. The aux in on your car stereo presents a very tiny load.

Actually everybody tell you contrary. http://www.hydrogenaudio.org/forums/index....st&p=764539 (http://www.hydrogenaudio.org/forums/index.php?s=&showtopic=89949&view=findpost&p=764539)
And You just open the new topic again and again.

Please refer yourself to last public test http://listening-tests.hydrogenaudio.org/i...-a/results.html (http://listening-tests.hydrogenaudio.org/igorc/aac-96-a/results.html) and some particular test http://d.hatena.ne.jp/kamedo2/20111029 (http://d.hatena.ne.jp/kamedo2/20111029)

Sorry, this and your other topics should be closed because it's spam and clearly violates TOS8 at this point.

Anyway, as not to appear to "stonewall"...
I have an iPod 3G 40GB, not an iPod classic, but probably qualifies as a classic in the spirit of the discussion. On it are tracks primarily encoded by Lame using a setting that works best for me based on personal ABX testing. The player has probably spent the majority of its life feeding a "HIFI" either through the line out via dock connector at home or in my car, or through the headphone out when connected to a system without a dock connector.

Hopefully this will keep the cycle of redundant questions at bay, but I somehow doubt it.

More to the point, this…

…is in direct conflict with this:
Public AAC Listening Test @ ~96 kbps [July 2011]: Results and post-test discussion (http://www.hydrogenaudio.org/forums/index.php?showtopic=90403)

Seeing as you’ve closed the latest single-question thread about iTunes Match, that saves me from having to worry whether it’d be worthwhile to merge that, and its predecessors, with previous discussion(s) on the service. To reiterate what you said in your post to that thread, users are somewhat expected to have searched before posting and to use a suitable dedicated/official/gigantic/whatever thread if one is available and their question is not radical enough to warrant a podium of its own.

Yes. I purchased an iPod Classic earlier this year and upgraded my car stereos (2 vehicles) so that I could connect an iPod (digitally).    I only use it in the car...  I've never even tried the supplied ear buds, although I have briefly plugged-in a pair of headphones once or twice. 

The iPod is the most popular player, so it's the device most-likely to "nicely" digitally-interface with a car stereo.  The Classic is the only model that can hold my collection of 14,000 MP3s.

I rip to MP3 with EAC/LAME and then use iTunes to "sync" the iPod.  Otherwise, I don't generally use iTunes.  For listening on the computer, I use Winamp.

I rip to LAME 'V0' and I just don't worry about sound quality...  Whenever I've heard a defect and gone-back to the CD, it's turned-out the defect was also on the original CD.    I'm sure a more-compressed option would also be fine, but I've got plenty of disk space for V0 MP3s so I've never bothered with a more-compressed format.    If I had chosen AAC, I'd do the same thing...  I'd just rip to a high-quality setting, and wouldn't worry about it. 

I would have no hesitation connecting the iPod to my hi-fi/home theater system, but I've already got a laptop (and a CD player) hooked-up in the living room.

I rip CDs with Apple Lossless.
I buy audio in MP3/320, MP3/256, AAC/320, AAC/256, AAC/192.
To save space on the iPod Classic, all music with bitrate higher than 128kbit will be transcoded to AAC/128 during the sync.
I never had any bad experience with the result.

Is it? I hooked up my Cowon iAudio D2 to the AUX of a rental car recently. I had to set the volume way higher than I have to with my in-ears (volume setting '40-50' versus '10'), and the battery was draining much faster. At least, that was my impression.
Title: Do you have an iPod Classic?
Post by: greynol on 2012-06-19 16:33:33
Yes, it is!

What do you think the input impedance is on the Aux? What is the output impedance of the player? What is its topology? How much current do you think is being supplied?  How much power do you think is being transferred as well as being dissipated within the player?

Do you expect the battery to drain quickly with the volume cranked but with the output disconnected?

Unless the input impedance is small (<10kohms), the output is something like class-a, or matching transformers are involved (refer back to the input impedance), we're talking about a very small amount of current being expended.

Yeah, line out is just pushing microamps, so basically no power at all.  Should be similar to running the player with no headphones at all.

At 10k ohms I was being extremely generous.

For some reason, high output level does seem to take its toll on battery life, even with high-impedance loads - but that's on tiny-battery devices like a Clip+ and would be expected to be much less pronounced in devices that are more power hungry to begin with. I'm not exactly sure why this is; maybe feedback resistors are smallish in value, or the headphone amp even is a Class-G/H affair. No idea what sort of amplifier topologies they're using in CMOS ICs these days.

To answer the original questions, I have two. An 80GB purchased in 2007 and a 120GB purchased in 2008. Both get used on my Yamaha A/V receiver via a Belkin ipod dock. I encode using LAME at the V2 setting from the FLAC files stored on my hard drives using foobar2000, although I have been thinking about using AAC.

I don't have one of the models currently being sold as the "iPod Classic", however I do have a 3rd-generation iPod Nano, which has been in heavy usage since I got it in 2007ish. It wouldn't have been my choice to buy an iPod, I would have chose some other player by a less loathsome company. But I won it in a contest, and I've yet to replace it, since it's been holding up so far.

I have listened to it with headphones, through car stereos, and full-sized home stereo systems, and it's performed well under all those circumstances. The only beef I had was that the iPod's equalizer was terrible - it'd create internal clipping, it doesn't let you actually change any bands but only select useless presets like "rock", "dance", "acoustic" ... bleh. But in terms of just straightforward, flat audio output - it's worked great.

Since my model is only 4 GB, I've recently started compressing everything on it to 128 kb/s AAC with the QuickTime encoder, to save space.

Same with the Classic. It's inexcusable and uncharacteristic of Apple's attention to detail, IMO. It can be worked around by running mp3gain/aacgain on your files (they get attenuated enough that the EQ presets no longer clip).

To answer the OP, I installed Rockbox on my Classic (latest model), which I use with headphones. I transcode my FLACs to Musepack --insane, which is probably overkill but sounds great (transparent). I find Rockbox's 10 band EQ much more useful than Apple's presets.

That's not necessary. You can select the option to re-encode everything to AAC/128 during the sync. So you can keep all you stuff in best quality while your iPod receives only the re-encoded stuff.

I have a 6th gen 160 GB Classic, and I quite like it, although I do prefer the scroll wheel on my previous 5th gen "Classic". (feel/tactile response)

Almost 14,000 songs, in my preferred/tested format of Lame V2 MP3. (I've got 10X that much, but have been lazy choosing what I want to sync over haha)

I rip my CDs with EAC in secure test & copy mode, to FLAC (for my archive library), and do any conversions with foobar2000 (for my MP3 library - ipod). I edit tags with MP3Tag. Foobar + foo_dop for ipod syncing. (now, if only I could figure this (http://www.hydrogenaudio.org/forums/index.php?s=&showtopic=45160&view=findpost&p=796433) out...)

I listen to it in my car via the headphone jack > AUX IN. (the cable was a gift & I haven't replaced it with a line-out cable yet - I actually like how it sits nicely in my cup holder this way) It works fine tho. (and that may be the setup some people use RE: battery life discussion)

It gets plugged into other people's hifi's at parties sometimes - works great. (i love portable players for that kind of aspect) I also use it camping etc. with an Ion Tailgater - great stuff.

At work, it's like this for my entire 10 hour shift: iPod > line out > Fiio E11 > Denon AH-D2000 headphones. Heaven!

They fixed the EQ clipping on iOS5, IIRC, but, at the same time, they completely borked Sound Check, it gets disabled when you skip a song. Crossing fingers for iOS6!

^Which means that they're aware of the problem, but can't be bothered to fix it on previous iPods.
