    The Headcase Stax thread

    Can the volume of the two channels be adjusted separately? Not 100% sure but I think this is the first machine made by stax which has a 4-way VR, not even for srm-monitor which also has a balanced input

    Stax SRM-T2

    Just bought a japanese hifi magazine issued back in 1995. It has the great omega+T2 combo on its cover with four pages of technical info of the t2. A nice collector's item under $20.

    Stax SRM-T2

    Wow...... The pics is back......true gem in head-fi history, thank you for uploading them again after years btw the t2 is much smaller than I thought with a headphone stand at the side for comparison and the way they put all the relay at the back as well as the way they put two sands in a single heatsink is funny

    black-anodized CNC aluminium case, sheep skin with memory foam earpad, copper electrode with 25% more open area than typical stax models, carbon fiber skeleton on the electrode and plastic parts made of industrial grade 3D-printed nylon. The electrode design is similar to the omega driver I posted eariler in this thread. Regarding the diaphragm and the coating, I can't speak too much but the coating is nothing similar to what you can buy in Walmart or Amazon. the diaphragm's active area is 90mm. The sensitivity is similar to 007 but lower than that of 009. Its sound quality is very interesting. its tonality is similar to 007mk1 and less darker but the clone's detail revival ability and soundstage size surpasses 009. The only weakness I noticed is the bass. 007 gets more punchy bass and some people might prefer how the bass is presented on 009 more. IMO stax sacrifice quite a lot of other aspects of sound quality to produce a better bass on its top model.

    I have just made a prototype of my O1 clone. Now I am working on standardizing the procedure of making this headphone as well as its headphone box so that it doesn't look DIY

    Speaking of T1, I noticed that some of the earliest T1s have two transformers replacing the voltage divider in most other later T1s. Will this lead to sonic improvement?

    srm-1/mk2 is good, but t1 is better, in terms of colouring of sound and texture. But since 207 is just an entry model so it doesn't matter much.

    Could the problem be the grounding of the amp?

    ESTA 4u inside

    Wow I haven't seen anyone owning two pairs of them before.Wiring them two speaker per channel makes them comparable with floor standing electrostatic panels. There was an offical accessory called JS-2 , a speaker stand for esta-4u. Although I couldn't find one for sale but I diyed one.

    Few days ago I bought two pairs of stax esta-4u Extra speaker and I am planning to play them two speakers per channel. I heard that Stax ESL speakers are amp-picky. Do anyone have any experience with stax ESL speaker ? I think my firstwatt f6 doesn't have enough power for even one pair of them......

    By hitting the headphone imbalance may go away by a chance of 50% . But the imbalance will 100% come back in the next ten days.

    Its hard to find wires that are thicker than the stock ones. And you may want to keep the stock wires after replacement because you need to put them back before you send the 007 back to Japan for service.

    Replace the tiny wire conneting the driver and the cable with bigger ones and with a more secure solder point.
