I think, given that there are differences, it shows three things
- That you can make good recordings with modest gear
- That (arguably) that little difference between good and great (which none of these were IMO, but in principle at least) can be achieved with the top hardware
- Its an illustration (by what can be done with modest stuff) of when to go for the top gear - theres a lot to be done with lesser stuff if you know how, and the top stuff is likely useless to you if you dont know what youre doing.
