Stumbling towards enlightenment
(Formerly known as kayandjohn.)
Just to be clear, the title of this thread is erroneous, the Bushmills are not closed, they're vented. Also, there are 4 different kinds of Grado earpads.
1) - The S-cush, a.k.a. comfies,
2) - The L-cush,
3) - The G-cush.
All of the above come as standard equipment on the current Grado line.
4) - The Flats, wich used to come stock on vintage Grados. The limited edition HP1000, and if I'm not mistaking, the RS1 also used to come with Flats.
From what I've read, TTVJ (Todd The Vinyl Junkie) has bought the remaining Flats that were left in Grado's inventory. They have a tendency to boost bass responce, and reduce treble extension.
Hope this helps.
Question... what is the difference between #1 S cushion ("comfies") and #4 Flats?
Answer (partial)... one has a hole in the middle, as used on the HP1000 and RS1 with buttons; one does not have a hole in the middle, as used on the current SR60e, SR80e, and SR125e.
