[Any thoughts regarding playing ripped CDs from a hard drive and how that compares to different levels of transports?]
Glad you asked.
A good well built ROM drive will yield better rips. And also store those rips into SSD instead of spin disks.
I can recommend this Pioneer ROM:
I have the older S11j (non X version). The good thing about this Pioneer is that they have a software/utility that allows you to slow down the spin speed. From my experience, the slower speed you use to rip, the better the SQ. Less vibration and less read errors. The X version has more rubber/silicon to damp vibrations. Really good stuff!
I have older rips from Plextor, LiteOn and Asus ROM drives but this Pioneer takes the crown. And yes, I sepnd many many hours ripping and re-ripping the same CDs using different ROM drives for many years.
Of course if you buy a very expensive CD/SACD transport with much better damping and much lesser read errors (Esoteric VRDS), it is going to sound better than CD rips.
Even though CD music is just 1s & 0s, but the amount of errors play an important part. That’s why in the golden era of ROM drives, there are many websites reporting read and write errors of different brands and models.
If record companies were to re-digitise their master analog tape into hi-rez files and you can buy them direct (DSD or 32/768 wav), think there won’t be a need for transport, but more on the higher end interface instead (eg. USB or I2S ports)
Hope this answer your question.
