Differences between cd transports?

Zimmerma rather than more useless and redendant posts on wire directionality from Don Quixote, ie Mr. Kait, polluting this thread and the Audiogon site in general, here is a reference that explains his position, not that it really matters:

Nothing new to report ......the story remains the same. That same horse has been beaten solo by Mr. Kait here 100s, maybe thousands of times. I guess when you are in the business and have little to offer of value beside Teleportation Tweaks, Clever Clocks, Brilliant Pebbles, and Dark Matter, any publicity is good publicity.

" I mean that all wire and cable will *sound better* in one direction than the other direction."

Rather than expensive hifis with all those wires (not to mention all the other integrated electrical components some lazy engineer stuck in there haphazardly with consequences unknown), a true purist might consider dumping all that and listening to two tin cans with a single wire connecting them to have an very good chance of getting it all right.

I’m sure rebbi is grateful for all relevant advice regarding CD transport differences including Geoffkait’s wire warnings and is considering it all appropriately for what it is worth while rolling his eyes and maybe even heading for saner turf elsewhere.

Hey Reb, hope all is well.

Many things might account for one digital source sounding different than another. Jitter is probably the most common culprit. Some DACs can correct for that, others not.

Assuming transports are working properly, there is also often errors in reading optical discs in real time as CD players must do, especially with poor quality, defective, or damaged discs that can affect results differently from transport to transport. Ripping to storage first using good ripping software that can assure high quality rips by detecting errors and rereading as needed.   Streaming  then tends to produce more consistent high quality results compared to reading an optical CD in real time in order to play it. 

Note that just because a CD is or looks new does not mean it is of high quality. You find when ripping CDs to disk that the speed at which the disc can be ripped varies with disc quality and disc quality cannot be determined with visual inspection alone.

Can you elaborate on what the sound differences were and to what extent? Differences in dynamics, detail, sound stage and imaging I am guessing?

Also what is the DAC?

Thanks.
