Very Nice.. thanks for sharing that. I believe from what I am told that the 604 was the studio standard for monitoring speakers for many years.. and the same person that told me that said that when you find an original recording that was made using the 604 series and you play it back on 604's.. it really sounds fantastic. I've come across a bunch of recordings from the late 50's into the late 60's that just seem to sound especially good on my 604C's..
I wish someone could come up with a list of either recording studios or albums that were made using the 604. It would be a real treat to start tracking down as many as I could
