A transport DOES NOT send out "1's and 0's"! It sends out an analog AC signal just like a phono pre-amp, tape deck, amp, DAC, etc. This analog signal is a representation of the digital stream of "1's and 0's". The way the signal is handled with the power supply, circuit elements, transistors and shielding ultimately determines the sound of the transport the way it would in any other component. (The only difference is the transport's signal combines both the L/R channels.)
Therefore, the things that affect DACs, amps, etc applies to transports with respect to power cords, IC's, vibration control etc, etc, etc.
If all they did was to spin the disk and send out digital bits, then they all would pretty much sound the same. Howerver, the build quality, engineering and design of transports varies and is directly related to price - and why the more expensive ones generally sound much better.
