More Stax Measurements: SR-009; SR-007; SR-507; SR-404 Ltd; SR-404; and SR-003
Unfortunately, I just did a quick listen on each and didn't have time for listening tests, so other than a couple of notes here and there, I'll let the measurements speak for themselves.
We'll start with the round ear-piece; the rectangular ear-piece Stax will be on the next page.
Stax SR-009 New Out of Box (# SZ9-1278)
This is a brand new headphone of the second batch of SR-009 (shipped about mid-Sept '11), fresh out of the box. Compared with the first pair of SR-009s, which had some break-in time, the measurements are near identical with the exception of the THD+noise. It will be interesting to see if anything happens after they're used some, though it's just as likely an error in measurement. I'll be re-measuring these after RMAF.
