I have to say sound is so subjective in many cases. We should all be able to pick out bad heads and poorly tuned drums, and a change of heads can really change the sound of any set.
So basically it seams a lot of people are trying to find newly made drums that sound like the vintage counterpart. I think in many cases just sitting behind a vintage set gives a different feeling then behind a new set. The same goes for other instruments and cars.
There is nothing like a 60's muscle car. It can't be duplicated in regards to the feel and over all affect a car like that has.
Drums to me are the same way. I have a 2004 set of Premiers that are so well built and sound amazing, but something draws me into sitting behind my 70's Slingerland and it is a different feeling all together.
If the music dictates a newer sound I would probably use newer drums to achieve that. If the music is from the 60's then I would use the drums for that. To try and get an old set to sound new and a new set to sound old, is it really worth it.
I guess also many people do not have the luxury to have more then one set so with that said I can understand trying to find the best balance between the styles of music you are playing.
In all cases I would probably find a local custom builder that can sit with you and show you the differences and what they can do to find that balance for the music you are playing. So much is available out there, just take your time and ask lots of questions. There are some really amazing builders that know their woods and the sounds they achieve.
Sorry, this is more of a general post and not necessarily for the topic currently being discussed.
