Using iPod Classic as music server

I finally decided to organize my music on a "server" using an iPod Classic that I got as a hand-me-down from one of my grandsons. In order to replicate music as accurately as possible I'm ripping CDs using Apples lossless CODEC. My understanding of these formats like FLAC and ALAC is that accuracy of replication is 100% and I'm finding that playback using earphones or good buds at least, seems that that is so.

However, when playing through my system, although good, playback using the iPod is not the same as when the source is the CD player. The information seems complete and obviously better than compressed versions I've heard but resolution and detail in the upper frequencies seems to have been softened.

My ability to compare these two sources is straightforward because I can have the same track playing on both sources and A/B using the source selector on the preamp. Now il get to my question.

First I need to say that the present system performs extremely well for my listening tastes so I'm not questioning the existing components. However, there are at least the 2 new issues of concern; one is the quality of the CD transport in the computer and the other is the quality of the iPod playback. I don't mean to imply that the playback from the iPod is terrible. As a matter of fact, it sounds quite good but a little softer/warmer than I prefer for critical listening.

There must be a reason why dedicated music servers are expensive and I'm assuming it has to do with reproduction quality as with other components in a system. I've never seen one so don't even know the process(es) for downloading music to them but, for several reasons, I want to pursue the use of a digital server of some kind. I'm, therefore, asking for corrections of my assumptions as well as some guidance toward making an intelligent choice.

My present system is: Shanling S-100 CD player, Peachtree Audio Nova as a preamp, Peachtree Audio 220 amp and Martin Logan Odyssey speakers.

The iPod dock will definitely be better. You can also reclock it with Synchro-Mesh to make it even better:

Power supply and coax cable both make a big difference here.

Steve,

If you have an Off-Ramp, is there any benefit to using the Synchro-Mesh, or does the Off-Ramp reclock just the same?

AppleTV IIRC resamples the audio to 48kHz.

If you want to use this route, I'd recommend getting an Airport Express which will send out 44.1kHz

Both will work with Airplay from your iTunes server

I appreciate the input and if I understand the full meaning, it looks like the only way to experience CD quality sound is to use a CD. That being the case, I'll suspend further experimentation and replace my 60GB iPod with a model that will work with the Pure i20; I'll still use that or the Apple TV for background listening.

On e you have an iPod that will work with your dock you should be very close to CD capability. If you had a CD player that also had a digital input you would, in theory, be using the same DAC with different transports. I don't know how much difference there would be between your lossless iPod files and Redbook CD, but it should be negligible for anyone willing to use an iPod in the first place (not intending any judgement with this statement just suggesting that using an iPod is likely an indicator that your gear isn't likely the elite extreme high end). I don't know if I could tell a difference in my system or not.

I have heard computer audio that I preferred to the $30k Clear Audio turntable that had been playing seconds earlier and I have also preferred a similar turntable over CD in a direct A to B comparison. Bottom line is that CD, computer audio, and vinyl can all be great!
