King Sound Emperor: New Electrostatic Headphones! - Page 7

post #91 of 658

Pre-ordered them.

 

Will let them say hello to a KGSSHV, and rip them apart when they arrive.

Always willing to take one for the team. Thanks!

Eagerly awaiting your impressions guys.

Are you gonna use the HV's 580V bias or modify it to accommodate the lower King Sound bias voltage?

I'll modify it of course, but I'll test it on 580V too, for science!

And I don't know why they did not use the current standard pro-bias 580v. The only amp's I have on hand atm excluding the SRM 1 MK2 that is on it's way here are all pro-bias.

I'm moving to Europe to enjoy higher voltage?

Let me know how that higher voltage is doing ya...

+1, going to anticipate on Birgir's findings once he rips the King's apart.

Don't smoke them....and measure them stators for me if the sound from these turn out to be worthwhile.

Maybe to prevent head to head comparisons with cheaper lamdbas out of the same production stax amp?

And/ or to have better chances to sell their amps?

And/or because their profit margins are such they're better off selling amp and cans as a package?

And/or because their amps are voiced / designed for these particular cans and they might not sound as good out of other amps?

In practice, keeping a reasonable volume level, isn't ok to plug into pro bias plus anyway? (I.e, you just got a more sensitive phone that while arc at lower output level on the amp). It's not like the current non-stax stax amps don't already have sufficient voltage swing to smake sparcs between the stators anyway smily_headphones1.gif.

Good points, but plugging in a low bias stat into pro-bias will damage the stators. Plugging in a pro-bias into normal bias is ok just lower volume.

I don't think that the stators or diaphragm will be damaged. It's more likely that you'll hear some unwanted noise or the diaphragm collapses to one of the stators.

Bias is a fixed voltage level on the diaphragm.  Music signal does not drive the diaphragm, it drives the stators (outer plates).  So bias level is independent of volume level setting.  You can arc the diaphragm with excess voltage without ever having played music or any signal through the headphones.

 

Their bias level likely has nothing to do with Stax, or amp capability.  Having proper materials and manufacturing controls for higher voltage levels is harder.  Chances are they are limited to the bias they have due to practical limitations and have set it based on tests.  likely going higher in bias gave them problems.  But there are many inter-related design issues.  Closer stator spacing would increase output but could require lower bias to prevent arcing.  So it would be hard to look at one item, bias, out of many parameters (stator spacing, diaphragm material, diaphragm coating resistance, thickness of diaphragm material, diaphragm tension, bias level, stator signal voltage) and conclude anything at all.

Well things aren't that simple as the bias voltage is inherently linked to the size of the diaphragm/stator air gap so use a higher bias for the given gap you will have noise issues and the risk of damage becomes greater.  The only way to say what is a safe operating range is to take the drivers apart and measure them.

Any idea on when these are expected to ship? Sold my LCD2, and don't have a main can atm. frown.gif

Drew Baird, P.E. and his first impressions of the NEW KingSound Headphone 1 (or Emperor as it was called at CES 2013 in Las Vegas) are: the Headphone 1 by KingSound is extremely detailed, fast, transparent and detailed like all electrostatic phones. But, here is the kicker, they actually have one of the best bottom ends I have heard from an electrostatic headphone. Drew has no doubt that this new headphone will be one of the hottest products for 2013 and Moon Audio will be selling them right here Moon-Audio.com.
