Raulirurgas,
to answer your post to mapman if I may be so bold. People are synthesising these old pieces of kit because they have a sound. A sound which is familiar and much loved by many. Yes equipment is way better now as you mentioned but it has no character due to its transparency.
So some want the character. In a recording studio this is very important. It brings a statement to a guitar or vocal or drum sound etc.
