scary moment huh?

 

 

Well, I had some old Lambda's that sounded fine even with holes in the diaphragm... ;)

CALIBRATED  holes....  

 

I think Machina Dynamica sells them.

They are indeed funny those "sounded great to me" impressions... 

post #21425 of 24765

I've actually seen multiple instances of people talking about Stax drivers with holes sounding completely normal. Maybe there's more to it than we think... odd.

post #21426 of 24765

Who's going to be first to pop some holes into their drivers?  

post #21427 of 24765

All right, got that SR-Gamma today...

 

...and it's imbalanced. Damn. Not only is the right-side driver generally louder, but the left-side driver also rolls off in the bass significantly even after balancing the volume, especially at 100 Hz and below. I don't see anything immediately wrong with the left driver compared to the right, either...well, except that the left driver's inner dust guard layer seems to be roughed up in a particular spot. But that wouldn't explain the sheer imbalance I notice here...

 

Also, the earpads are much, much shallower than I was expecting, which means my ears (pinnae if you want to get pedantic) touch the inside of the cups. Quite detracting from a comfort standpoint.

 

Other than those flaws, first impressions are that it does sound pretty good, if more closed in than a Lambda (likely because of the shallow earcups). I just wish I knew of a way to fix that left driver so I don't have to fiddle with the balance knob on my receiver.

Uh, Oh..

My condolences. However I'm up for buying it for half the price bigsmile_face.gif

On a few occasions the Realizer A8 clipped and it sounded like distorted bass in the SR-009s.  It didn't last more than 1sec each time.  I had the volume on the A8 set too high and it clipped on movie scenes with loud explosions. They don't really tell you that the A8 is susceptible to this in the manual!

 

On a second occasion I fed the DAC unprocessed dolby digital sound, which caused loud clicking/beeping sounds.  I immediately shut off the source.

 

The SR-009 sound fine.  Should I worry about any damage?

 

Thanks

Anybody who says that has never heard a fully functional set.  The distortion caused by just one small hole is clearly audible.

Anyone interested in a MINT SRM-727II, let me know, I'll be listing it likely tomorrow. smile.gif

You lucky dog!

Congrats! Great find! atsmile.gif

Broken Lambda Pro driver...

 

So I was inspecting my Lambda Pros, since the right channel sounded off. Turns out the driver had come apart - the back stator was not secured to the rest of the driver.

 

 

The photo below shows the problem (btw, I've only kept the stator 'open' like this for a few seconds; very briefly when I realized it was broken, and again just long enough to take this photo and scan for dust on the membrane). There is no dust visible to my eyes on the membrane, and the back stator fits perfectly on the ring to which it is supposed to be glued; i.e. there are no gaps. 

 

Anyone else fixed their stators before?

My current thinking is to use some 2-part epoxy (LePage Marine Epoxy) around the edges to re-secure the stator, and leave some weight (an old textbook?) on top of the stator overnight while the glue settles. Thoughts?

 

 

 

On the same topic, the 5-pin connector seems a bit oxidized - any easy way to remove the oxide?

A brief dip in (nitric) acid?

Err, nitric acid is an oxidizing agent...

Thanks! Really enjoying it so far. smile.gif

Quick question. On the new Stax portables...are they more like earbuds (sit more on your ear canal) or IEM style headphones? 

 

I can't do in ears (due to wax impact problems), but ear buds are fine and I'm pretty interested in a pair.
