You have got to be kidding.

 

OH wait, you probably mean the 007 MKI. The MKII and III are total fart machines, the MKI is not...

Fart machines? Is it their diet or....?

It's their ports.

The orifice that vents air from between your cheeks and their transducers.

Yep, I mean the mk1 wink.gif

Ugh, after years of owning the o2mk1 I feel like I'm starting to get the Stax bug.  Last week I think I came away preferring 407 to the esp950  out of a 007tii and I've always loved the Koss.  I'm trying to sell the Stax amp and maybe find a SS solution instead for my secondary rig.  Also ordered some 507 pads to see if it makes the 407 moar betters.  The Stax pads are adhered really crappily it seems, my OCD sense is killing me.

 

What is this I see about the 207 being the favored set of the modern line?  I don't get it!

I think the implication is that the new models all have common drivers, so it becomes an issue of the frame introducing mechanical resonances which affect the sound. A few people have heard all the x07s and concluded that the 207 is the most neutral of the lot.

Been messing around with sinegen and electri-q with my sigma NB. Anyone interested in a healthy discussion? It really made a big difference bringing down the boom-ish mid-high bass and up the sub-bass, along with adding a little in the presence region.

 

I am on the fence about what to do with 1 kHz - 5 kHz and also the treble region, which is largely in line with 200-1000 Hz with just a little extra volume past 15 kHz.

Is there anyone that can give a full description of the Airbow SC21?  It would be helpful if there could be a comparison to the Stax SR507.  I've read that the SC21 rivals the Stax 009 but I'm very skeptical of this claim.  Its very rare to get even a small amount of information about the Airbow except some blurb in Japanese from the manufacturer.  If this post belongs in the Stax forums, let me know.

I think the choice is clear

Apparantly according to spritzer the SC21 and 507 are identical minus the cryo'd bs Airbow puts on all there stuff.

I gather that this forum requires 'self-responsibility'.

...

 

 

I'll post some 'scope pictures if I get around to it. Square waves even as low as 1 kHz don't really look all that great from the output of a T1 driving an 007 at ~90 dB SPL, while the DIY T2 is close to flawless.  

 

Why not use Vrms, as in this system it is the only variable, and is listed on all the available amps?

 

Also, it should be possible to calculate and plot the spectral response of an amp at a given loudness. You could also calculate the SPL at which the amp becomes non-linear, and predict square wave form.

How is Vrms the only variable of an electrostatic system? It is one of the least important characteristics of an amp in my opinion. Obviously you have to have enough, but any electrostatic amp does (otherwise it's just a pointless design). There are tons of other characteristics that will affect the sound way more than max Vrms swing.

post #1905 of 3374

Loaded slew rate at 20 kHz defines the maximum output of the system, and as frequency and capacitance are fixed, the peak voltage is the only value that needs to be examined.

 

Or perhaps you disagree. I am not an electronics student; I am just a good customer.
