"Electrostatic headphones, like electrostatic speakers, work on a push-pull arrangement. When one of the stators is going up in voltage, the other stator must decrease in voltage so that the diaphragm can move due to the static charge. " Kelvin Gilmore Unlike dynamic cans which have a signal and a return cable for each driver, electrostats have a additional bias conductor, which provides the power to "drive" the electrostatic drivers. As such, there are 3 conductors to each driver in electrostatic headphones. The difference btw pro and normal bias is the bias voltage (abt 230V for normal and 580V for pro) that drives the earspeakers. Normal bias earspeakers have 6 pins on the connector while the pro have 5. Stax didn't have pro bias earspeakers and amps until 1979-1981 with the introduction of the SRM-1 amplifier. Thereafter, most of the amps have both normal & pro bias jacks. The normal bias was removed from their amps with the advent of the SRM-717 in 2000, hence all (if I not wrong again) the newer Stax amps from them are all pro bias. However, it must be noted that different manufacturers have different bias settings for their headphones, which will affect performance and longevity of their products; eg, HE60 540V, Jade 600V, Koss ESP950 600V. Generally, more bias volt will better drive the headphone but over doing it will shorten the life or kill the headphone. Note: You can plug in a pro-bias earspeaker into a normal bias jack, no damage but just poorer performance from being under driven. Do not, however, plug a normal-bias earspeaker into a pro bias jack as that would effectively kill the normal-biased earspeaker. (Stax headphones are known as earspeakers). But then again, you wouldn't be able to plus the normal-bias earspeaker into the pro-bias slot because of the 6th pin on the earspeaker end. Any other pros please chime in if I made a mistake in the above.

SOURCE IS EVERYTHING!! Right now, you just need a good transport for your Xindak DAC and with your coming fire chicken, your quest is complete.

ical 0 Report post Posted November 3, 2009 (edited) At $30k, they're the flagship series and one of the best combo around. Obviously they've to be good to commend that price. You want to borrow my friend Clear Audio Statement? Bro, compare with something within your budget. No need for Reimyo. Just get a normal cdp and use it as a transport will exceed what you've now. ai, i saw something post your new toy pal Camera down.
