Can somebody provide some info on how the ESP9, when driven by an E9 box, compares with a Stax electrect such as SR-40/80 driven by a transformer box like SRD-4? sound quality wise.
Birgir? Edstrelow? ericj? Anybody?
I had both of these at one point and felt both were fine phones. The big plus with the ESP 9 , which I still have, is that it provides a great deal of attentuation of external sounds. It has good bass and dynamics which depends somewhat on the supporting amplifier.
The electrets, which I did not keep, were decent but with no noise attenuation and not such solid bass. They are very light compared to the ESP9.
I personally think that these electrets, and many Stax phones have a somewhat honky mid/upper midrange which I really notice when I compare them to the Koss ESP9.
One other plus with the electret is that it should be able to be run off a Stax amp as well as the transformer. So far the ESP 9 eludes my ability to get it to sound good on an amp.
