Thanks! Same colours?

There should be no problem. But remember that a 3.5 watt amp driving a SRD will probably only provide a max of 150 volts to the stats. Most SRM's can deliver between 300-400 volts. Some of the aftermarket direct drive amps can deliver as high as 1500 volts. Your little amp may clip easily. If you hear any clipping back off on the volume.

With the 5 pin standard both diaphragms are connected to the right bias pin. The extension cord is a flat 6 core cable and there is no color coding. Stax doesn't use double insulation like Sennheiser did with their stat line. It's best to use a continuity meter to check what wire is what and reuse the crimp connectors that connect too the drivers. You can solder but you have to be very careful with excess flux and castoff.

That looks a whole lot like a Dynaco ST-70, with a small gain stage (preamp) added upfront. Interesting...

WoW

i am like forever indebted to you guys

i've recently been getting into classical music - symphonies and orchestral suites.

after getting my first electrostat rig and upgrading my dynamic rig

the electrostat rig is simply mind bogglingly worlds ahead of the dynamic system for clarity, detail and definition in classical music. i simply cannot listen to classical on my dynamics without feeling like i am in my car listening to its stock speakers losing ever last glimmer of detail and finesse that is embodied by well produced/recorded classical

listening barber's adagio for strings, mahler's symphony #5 and rodrigo's concerto aranjeuz are like a completely different experience to me, in particular is string instruments and complex passages is where the stats truly shine, effortless in presenting the detail

my appreciation for the skills of of the musicians is greatly increased as i can hear that much more of their performance that it astounds me, dynamics sounded nice but amalgamated the sounds all together so much i really couldn't hear each strut of the violin strings and pause taken before each trumpet blow, just incredible. my respect for musos has gone up 1000%

i think for piano, in particularly beethoven's moonlight sonata i think the dynamics have a bit more impact and visceral thud and warmth...

argh, and don't even get my started on vocal/operatics...

There are so many variants of Stax energizers & amps around. Just curious if the improvements of the 006t or the 006tII are significant over the older T1, T1s variants.

Welcome back!
May you have a more enjoying stay this time...

Nice find!
I sure would be interested in more information about this amplifier. Especially if someone have ever listened to one.

Looks like a great versatile amplifier.
I think its 2 x 3.5 watts might be a bit on the low side for powering a pair of Stax phones through an SRD-7 Pro. Keep us posted when you have listened to it..

Stax non pro Sigmas and the Stax Intergrated Amp 125

Well, going to the NYC show in Bayside, NY got me going a little bit. You see, like all of you out there, I am also interested in great sound and may be a little to willing to pay $ too much to get it. So the next day, I went down to Lyric Hi Fi on Madison Avenue and saw a used Stax Intergrated Amp 125. I previously had been using a Stax SRM1/MK2 to run my two pair of Stax Sigma Low Bias headphones. I thought I was completely happy with this set up. I ask the Salesman, Bob, what he was asking for the used Stax 125 amp. He responded a certain number $ and I negotiated $50 off of that price. We both were happy. So when I got home and hooked them up to my headphones and my favorite internet radio program, Hearts of Space, I was completely flawed by the sound produced by the used Stax 125 amp. To put it mildly, the Stax 125 amp running both of my Stax Low Bias Sigmas were an significant improvement of the SRM1/mk2s. Dare I say that they sounded better than my Stax Omega 2s with my SRM007t tubed amp. Oh my god; is this allowed to be said on Headfi.org. Well, that was totally my impression.
So, if you happen to have a old pair of non pro sigmas around- try using the 125 amp as see if you agree. I will state that I am of sound mind and body when I say this. Enjoy the day. Scottsmrnyc

I take it that your talking about a SRA-12s Stax amp? I love my 12s. I prefer it to my SRM-1 mkII pro on the low bias Lambda, SRX-III and SR-5. The 12s has a mellower tonal balance than the SRM. The bass is more pronounced and seems deeper. The midrange is a little more laid back. The 12s is also well designed and made. All the separate circuits are on plug in cards with gold contacts. It can also be used as a passive or active line stage with pre outs. It has a good MM phono stage and a tape loop. I have a Behringer EQ in the loop. It gets quite hot so I have a low speed fan on top of it. The SRA-12s was the preamp to drive the DA-80 and DA-300 class A amps back in the late 70's. The owners manual shows the whole system including the big Stax full range ESL loudspeakers. If you ever want to sell it I have a friend that would buy it. Enjoy!

If you want a decent little amp with more bass output, either the Trends t-amp @ $100 or the Firestone Audio Big Joe @ $210should do the trick as neither have the rolloff in the bass that the SI t-am does. I imagine the bass increase will still be small doe to the phones limited response down there.

Correction- Stax Intergrated Amp 12S not 125

I just didn't have my glasses on to see the numbers on the unit. Enjoy Scottsmrnyc

Carl Doubtful! What is doubtful?? I just bought one at

At Lyric HiFi on Madison Ave and E83 in Manhattan, nyc. They were on the used equipment shelf tagged at $300. I negotiated the price to $250. I guess I was in the right place at the right time. Enjoy Scottsmrnnyc.

He was talking about the Masters Stax amp pictured above.
Nice find for both of you though.
