ExactAudioCopy ripping software

Isn't there some sort of loss in any compression/expansion scheme?

I don't think so. You can take a digital file like a picture or a music file or a spreadsheet or a Word document or whatever and compress it using a any of a wide variety of programs (like Zip) and when it is reconstructed it is exactly the same as the original file. Where is the loss?

Hi
I bought the 500 Gg HD separately,Sonos does not provide.
Sonos (current models)force you to their crappy DAC - giving only outputs for amp.
What I liked about Sonos over Sqeezebox is the incredible LCD remote.
What extra advantage does the SX-5000U2 USB Device Server that you recommended provide?

Does anyone else have an opinion of compressed VS uncompressed?
Thanks

Fatparrot: There is no loss when decoding an encrypted FLAC, Apple Lossless, or WMA lossless file. I'm sure there is some way to prove this mathematically, but empirically folks have encoded literally millions of music files in these formats and there has been no published instance that I know of where a file did not decode correctly when the software worked properly. That is certainly enough experimental evidence for me to believe the lossless claims.

Some folks claim to have heard differences between FLAC encoded and WAV (unencoded) files on some systems, but given the subjective nature of audio it's hard to know if this is a real or imagined difference. There is some thought that the processing required for decoding may effect the overall audio chain and introduce some difference if it sufficiently taxes the system, but all of the algorithms I mentioned require very little processing to decode. On a PC or Mac where computing power is in abundance, it's not likely that there would be any effect. On a Squeezebox or Airport Express unit where the processor is significantly smaller there may be a possibility, although it's hard to imagine how it might occur. I have a Squeezebox and have it set up to decode my FLAC files on the PC first and then stream PCM (WAV), and I hear no difference between the FLAC files and the original WAV files from the CD.

Note that none of the things I mentioned are due to incorrect decoding of the files. Lossless means just that and the only difference between an encoded file and the original WAV (or AIFF) image is size and the ability to store tags information.

Saffy, I looked at the Sonos website and it says their players do provide a digital output and that they can handle all manner of files. Perhaps you have an older model?

My opinion is that a USB DAC is the way to go. One of the weak links in digital playback has been the jitter introduced by the spdif interface and cables. USB supposedly takes care of this or at least greatly reduces it. The problem for now is that it can't go wireless. The USB device server I talked about has zero advantages because as I stated in the previous post it isn't compatible with USB DACs. Silex was telling me they hope to have a wireless server that can handle USB DACs very soon.

Herman: There are a number of folks providing mods for the Squeezebox 2 and 3 but the two I hear about most are by Boulder Cable and Red Wine Audio. Both of them have internal modifications for both the digital and analog outputs, plus an enhanced external power supply which is reputed to make a significant difference. Many folks have reported improvements by simply swapping out the stock switching PSU with an inexpensive linear one. If your interested in details, you might want to take a look at the Slim Devices audiophile forums. There have been many discussions about the various mods and their effects.
