Differences between cd transports?

The drive circuit board may be proprietary as is the Cambridge CXC drive circuit board, but it sure looks like it has the Sanyo SF65 laser and mech in it.

SIMAUDIO MOON 260D-PCM1793-Sanyo SF-HD65

Can be ordered with or without dac section

Never found Vassili’s list to be wrong yet.

Please explain precisely what you mean when you say that audio wire is "directional."

>>>>>I mean that all wire and cable will *sound better* in one direction than the other direction. This is true whether the wire or cable is in a DC circuit 🔚 or an AC circuit. 🔛 The more wire and cables that are in the correct direction the better the system will sound. What wires and cables am I referring to? Speaker cables, digital cable, interconnects, transformer wire, internal wiring of electronics and speakers, fuses, capacitors, power cords, HDMI cables. All wire and cables.

" 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.

To geoffkait:
Ok.... so having directionality means that a cable will sound better when the signal is sent in one direction rather than the other.
Now.... what is the precise physical explanation for this behaviour?
