Some RCA cables also have the shield connected only to one side of the cable.

post #21407 of 24765

In my Oppo 95 -> Realizer A8 -> PS Audio PWDII DAC -> Woo WES -> Stax SR-009 setup, on 2 occasions there was a clipped signal being fed to the SR-009s. Worried that this may have damaged the drivers in the SR-009.  Would it be audible if damaged?

 

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

still, something like 001 is much more suitable for portable use.

 

The only Stax amp with a regulated PSU is the SRM-300/310.  Even the T2 was just a rectifier and a cap.

This is true but they have to have a return wire or they won't function.  The XLR's do not need ground.

actually the new srm002 portable has a fully regulated power supply.

But not in the same way as the 300/310

Yes. See a neurologist as soon as possible!

Thanks for the worthless comment.
If ever I want to waste my time, I'll ask you for advice.
post #21412 of 24765

i think you've answered your own question, "they sound fine" In my experience I've had inappropriate levels set and experienced no damage.

scary moment huh?

post #21413 of 24765

Your SR-009 will be fine, don't worry about it. Digital clipping of the source will not damage the transducers. The transducers simply reproduced the distorted sound as they should.

Ahaha. Well, he may not have liked it, but I did.

 

EDIT: It was a joke dude, cool out.

but i can somewhat understand , if i were to spend 5K on SR009, and were in his shoes ( worried about them having permanent damage), i'd NOT like someone joking about it.

post #21416 of 24765

Eh, I get it...but this is the internet after all. I'd flip if I had thought my 009s were damaged too (when I had them). 

 

Now I'll flip if someone jokes about my speakers. :D

That both surprising and disappointing!
I was always wondering how stax managed to cram all those circuits into such small enclosures.. now it's all clear..

Thanks guys. It's not easy to joke online as it's hard to interpret. I know I'm somewhat "anal retentive" but after spending so much money, I'm being extra cautious I suppose.

Completely understandable.

Milosz, that's a very cool explanation! Thanks for taking the time.
