It's ridiculous to say that if I buy an 8 channel preamp / sound interface, it's going to be obsolete in 3 years. What would be the point in buying it?
That was the point of the post.
Eg. I could buy a line only interface and use my half decent preamps, or buy an 8 channel adat mic pre-amp and use it for as long as adat is around on interfaces.
There are ways of future-proofing your recording equipment - it's picking the right road.
Recording starts with having a half-decent mic and pre-amp (if you don't just record line in sources).
Maybe a line only interface is the way to go.......
Jack of all trades, master of some.
