Nigel,
I can see how you feel left behind by the 'digital take over', and if you were new to recording, and had no equiptment, i'd definatly say go digital. But you have a full, working setup.
Both digital and analogue have their advantages. So before you consider swiching you should ask yourself;
Do you just want a digital setup because its newer and you feel behind everyone else?
If so definatly don't go digital, this would be the worst reason. Also recording is compleatly different to graphic design, alot of the best equiptment is that 'old stuff'; almost everyone here probobly wishes they owned vintage microphones, or top of the line Otari 2" 24 track recorder. You may not own the top of the line analogue equiptment, but you wouldn't be moving to the top of the line digital equiptment either.
Do you feel limited by what you currently own?
If what you have is all you need, then why change.
Would you really use all the extra features you would gain from going digital?
It's nice to dream of owning all the extra features, channels etc. but in reality if you arn't going to use them, their useless.
If you were to get a new digital setup you would have to spend a large amount of time familiarising your self with it, even though you do know computers, and it definatly doesn't mean the quality of your recordings would go up.
"I really do love my equipment"
If you are happy with your recordings and equiptment, then why change. If it aint broke, don't fix it.
Hope this helps you with your quest,
omni...
