Actually it's hard to tell what they are now and I've been using faust3d's Wikiphonia as a guide for finding vintage collectibles.

I originally purchased it with the SRD-X Pro adaptor's but I sold them off for cheap as I didn't need them. Then I managed to get another Gamma Pro from the same seller but without box, condition wasn't as good and the pads were the normal oval pads seen on most Gamma's.
 
Besides some flaking on the topside of the headband, mine is fairly NOS with foam intact and everything, no signs of previous tampering at all.
 
Pictures taken while ago as I was going to sell them to another buyer. I'm glad I didn't because it would be extremely hard for me to find a pair in this condition and the price I purchased them for.
 
I have done AB comparison against the other Gamma Pro with oval pads, this one sounded more forward but not bright at all, bass extension is superb makes my Lambda Pro's sound extremely laid back in comparison. All this attributing improvements could be due to the pads, which are soft and moulds right over your ears.

As for how it compares to the BHSE, the DIY is nice step up but it should be for the cost.  It's at least 5k$ in the parts alone if you can even get them.  Not everybody is sitting on a few hundred 2SC3675's like I am... 

 
Isn't that rather uncomfortable?  Is there a shortage of comfy chairs in Iceland?

 

[wink]

Solid state seating is very comfortable. Not like those hot tubes.

I was under the impression that the Alphas were identical to the Gammas, except for the pads - so what you have are a pair of Excellents, perhaps with the wrong logo printed on them  
 
Whatever you do, do not let anyone butcher those poor cans.  The Alpha/Gammas are wonderful headphones, and Spritzer is definitely going to hell for his role in encouraging so many people to cannibalize them for their drivers
 

 
Hey!!!!   I just sold one Alpha Pro Excellent that was completely untouched. 

  I did take the headband apart to fix the flaking though as black dandruff isn't too cool. 
 
The other Alpha Pro Excellent wasn't so fortunate though...

Poor Alpha Pro Excellent ~ R.I.P.

Probably a silly question but the pads that come with the sr007a now is black right? I don't really like how the brown pads look

i haven't been able to find a used pair and might end up buying one from pricejapan soon. 1k more for the us version is too much of a difference

brown pads are brown 
 
iirc yes, they're black.

Can you guys tell me if the black SR-007 are made of plastic or aluminum frame?

 

[padam]

Any kind of SR007 has an aluminium frame.

 

[TMRaven]

Ok, great.

I'm thinking of buying a SRM 727, whose voltage is set to 220.
I'm in UK and here Stax amps are sold with a 240 voltage. My current Stax amp is labelled as 240v (the 220v is clearly not checked so I assume the internals are different). Any problem?

 

[kevin gilmore]

so here are the thoughts on this
 
there are 2 sets of windings on the transformers, both labeled 0,100,120
 
for 120 vac (usa and others) the 0 and 120 sets of windings are in parallel
 
for 240vac (Germany and others) the 0 and 120 sets of windings are in series
 
for 100 vac (japan and others) the 0 and 100 sets of windings are in parallel
 
 
every time in the past I have seen units set for 220, they are actually set for 240v
 
but in theory you could wire 0 to to 100 to 0 to 120 and get 220v
but I have not seen that done yet.
 
you should open up your current unit and check.

 

[realmassy]

Thanks Mr Gilmore, much appreciated. I'll ask the seller to take a picture.

The old voltage selectors Stax used had a selection for 220V but I haven't seen it used in a long time.  Some of the amps from the 80's were setup this way before the EU raised the voltage to 230V. 

 

[shipsupt]

Now, if only the UK power company would follow the EU standard!  I'm still seeing over 240V at my mains at times.
