Gu Sensei's post of measurements of the SR-009s from a Japanese Stax thread raised some interesting discussion. While the measurements he posted are interesting as a conversation piece, there are questions about the quality of the data and methodology of the testing. The measurements are not nearly as useful as the type of through headphone measurements that our very own Tyll Hertsens has been making and posing over on the Inner Fidelity site.
In the want for more objective data on stats, Tyll has graciously agreed to measure electrostats if we can send them out to him in Montana.
The plan will be to coordinate people sending in their gear so that Tyll can measure the electrostatic lineup we are able to get to him off of a single electrostatic amplifier. As Tyll does not presently have an electrostat amp, we are going to have to send one. Voltron has volunteered his 007t, but if anyone has a higher end amp they'd like to send we can use that instead.
I'll be sending along my 009s as well as helping coordinate the effort. As Tyll is only able to measure a few headphones at a time, we will be assigning shipping dates via PM and the spreadsheet..
If this sounds like a good idea, and if you are willing to send in some electrostat gear to Tyll for measurement, please leave your information in the spreadsheet here. It will be great to have some quality measurements for the Stax range.
