I have an uncle with an extensive classical record collection, I've digitised part of his library, in the process cleaning up the sound - eliminating all the record noises etc. He still prefers to listen to the record. The digital music is "too clean."
I think emulation can be that way, emulation is too clean, too pure for the retro feel. My MacPro is rock solid, it can run rings around an Amiga, but some might find E-UAE running on it too pure, it isn't the 80's feel.
Me I just want to reminisce about old games I used to play, but it's not the old push your equipment to the limit feel, E-UAE almost makes the Amiga look too easy. The E-UAE process barely shows up on my system usage while running faster than any Amiga ever made.
In a way the Amiga experience was about doing a lot with a little. Pushing technology almost to the breaking point. I don't do that with m MacPro, video, high resolution images, 3D rendering, nothing even gets the machine "warm." In some ways it's like cheating compared to the Amiga.
Retro has it's appeal, I was once an amateur radio operator, I used to make contacts with people using 5 watts and an antenna thrown over a tree branch. The morse code was barely distinguishable over the noise. Now I use Skype and talk with people half a world away by clicking a button. It's better but it's not the same. India, the US, somewhere else in Oz, it's all the same. There's no thrill in it. This is why there will always be classic equipment lovers.
