Hi till five months ago I used these batteries (see the attached photo), but, at the moment I use the Baku BK-1502D+ power supply with great satisfaction. Best Regards

Hi Frankly, I don't remember how did the original baby stax sound ( I bought them from Japan in 2012), but, after modding, they sound very, very detailed with good bass. I compare them to my Massdrop Hifiman 4EXX with JDL Labs amplifier.

Hi Previously, I used rechargeable four batteries to power my Sr-001 MKII Stax headphones but five months ago I purchased a Baku stabilized power supply with variable output voltage that I use with extreme satisfaction. Best Regards

Hi I have modified the Stax SRM 001 as follows: C1>>> Solen MKP-FC C2, C27 and C28>>> Elna Silmic II C3>>> Elna Silmic II C17 and C18>>>Nichicon Muse Elna Silmic II 470uF 50 V between DC input and ground C7 and C8>> Amphon PF-XAL-AL 0,01 uF 630V I left the original NJM062L opamps...

AudioCats thank you for your reply. What do you think about the use of Ampohm Paper in Oil Aluminium Foil 0,01 uF 630v in C7-C8? I don't have problem of space, given that I'll put the amplifier in a new case. Thank you Regards

Hi AudioCats At last I have solved the problem of my Stax sr-001 MKII; I sent it to Joynetcafe (Japan) and Stax changed the Earspeakers unit under warranty. Now, it sounds good but I want to modify it as SuperFatCat ( I have put the PCB in a new case, so there aren’t problems of space)...

Hi On March 2010 I bought a Stax SR-001 MKII Earspeaker system from Joynetcafè (Japan) at 200€; very soon I heard a great signal distortion from right channel. So I sent the headphone to the Japan (48€); after twenty days I received from Joynetcafè my Stax under warranty (I had to pay further...

AudiCats I changed output Fets and Transistors but unfortunately I didn't solve the problem; after three minutes I hear an annoying distortion on the right channel. Do you think the replacement of the output Opamp could solve the problem? Thank you Ecodoppler

AudioCats thank you for your explanation. And If I change the output FETs? At this point I cannot to ship again to Japan and I could give a try to this amplifier. What you propose? Thank you Ecodoppler

Hi AudioCats I read with great interest your threads on Stax SRM-001headphones and I wish to modify mine but there's a problem; I bought my Stax from Japan one years ago but soon I noted a great distortion on the right channel. So I decided to send the headphone to Japan  to repair it; after...
