Stax SR-404 Signature used to be the top of the (Lambda framed based) line headphones, now topped by newest Lambda family member SR-507.

SR-404 are based on Lambda Nova Signature and feature a few technical improvements such as new thin diaphragm of only 1.35 micron in thickness. Lambda Nova Signature had 1.5 micron diaphragm but old Signature model had 1 micron diaphragm which was, supposedly, made from a different material. The coating of the diaphragm and plastic used for housing might have changed, as well the tension of the diaphragm itself.

These small differences all attribute to very audible differences in sound between various Lambda signature models.

In April of 2009 a special Limited edition of SR-404 should be released. The price for this new model will be ￥63,000. New special 6N OFC Silver plated hybrid cable and real leather earpads will be used. Top of the headband will feature "Λ SERIES 30th ANNIVERSARY" writing, earcup will have "SR-404 LIMITED" writing and color of the headphones is matte black. An early release picture can be fond on the right.

General Description of the Sound

SR-404 Limited Edition

SR-404 featured Lambda family signature sound with a slightly aggressive (hot) upper mids and excellent bass response.

The level of details is excellent across the entire sound spectrum and tonal balance is very lifelike and accurate. Overall all it seems to be a side step and not an improvement coming from Lambda Nova Signature.
