Hope you day was great...Happy birthday...just got back in town and saw this.

It is trying to come to American in a Big way....and probably will; sooner than later. Won't that be a surprise to the world.

I did a quick google search on "ES-1" "headphone inventory" and URL limited to head-fi.org and get 15 returns with 7 noted being in the members profiles. This is a neat why to search head-fi by the way.

Spritzer...you are correct in that I have been confusing these values. This extra that you gave me helped me a lot. One is the Power Supply swing the other is the output voltage swing. I was not getting this distinction before. Thanks

justin..thanks for jumping in and helping clear up my understanding... where is the peak to peak of 1200 voltage measured? This obviously is not the stator to stator measurement that you noted as being +/- 350volts. So if it were to run all the way to the rails it would be the spec'ed ~425volts RMS? So in the PR literature we have specs noted as being RMS and Peak to Peak and in your discussion above rail to rail. It is noted that Stax amps are spec'ed as having outputs anywhere from of 280 to 450 volts RMS depending on the amp except for the T2 which is 600 volts RMS. Are these measured at the same location as well?

I got it wrong in my post for the KGSS from Headamp per that spec. It is +/- 600 volts since it is 1200v PP. It is 425V RMS as noted in the first of my posts on this subject for the KGSS as spec'ed on the Headamp listing for Justin's KGSS. I would think the KGBH would be more like +/- 530 volts RMS being spec'ed at something like 1500v peak to peak (PP) or 750+/- volts. So to summarize hopefully correctly this time. Headamp KGBH --1500vpp (+/- 750v) or ~530v RMS Stax 727 -- ~1250vpp (+/- 625v) or ~450v RMS Headamp KGSS-- 1200 vpp or ~425v RMS Another interesting note is that on some of the Stax amps they are spec'ed having either 500x gain or 1000x gain. The 727 is noted as having a gain of 500x not the 1000x gain that is suggested as being needed for the SR-007MkII somewhere around here. I now am interested in the relationship between the gain and the voltage swing if anyone can provide additional insight I would appreciate it. My take, which is completely conjecture at this time, is that for the KGSS being a constant current amp is different from the Stax amps which may be constant voltage amps. Therefore the relationship between gain and voltage may not be consistent comparing these with each of these amps. Help from KG would be appreciated here. I am out of my depth but attempting to learn.

No, it apparently is not +/- 350 volts but something like +/-425volts for the stock KGSS.

For the KGSS design I would guess it would depend on how the builder set the PP voltage. On the Headamp site Justin specs a pp voltage of 1200 volts. It could be higher if he wanted to stress the components more I would assume by design. As you noted it could be as high as 495v RMS but it would appear to be set lower at about 425 volts for conservatism. Thanks for everyone's input.

Question for the gallery: When a spec states that an amp has 450v RMS how does that compare with 1200 volt Peak to Peak? Is it 1200 divided by 2 times 0.707 which approximates 425 volts RMS? So 450 volts RMS > 1200 volts PP, right?

The Ultrasone Edition 9s sound very good that way..I always say these make anything sound good out of them.

The standard XP operating system will see 4 GB of address space. If you have 4 GB of memory that will take up 4 GB of address space BUT..the operating system uses some space. The video uses some space. Other things use address space. That these things other than memory uses address space from the top of the 4GB down. Memory is given from the bottom up. Where these meet is how much memory is available to you. If your other things take up 0.75 GB of address off the top, all the memory that will be seen is 3.25 GB because that is all of address space available. Now there are extensions available in XP that allow address space of 12 GB and of course the 64 bit version which allows the operating system to see 64 GB of address space. That is the sum of it.

It is not flashy like the Yamamoto HA-02.

Went to work, then to cardio rehab then home for supper, checked in here then chilled. Now I am headed to bed for a 4 am alarm for tomorrow hoping the SR-007 that is scheduled shows up.

Is there an easy method of cleaning out that debris?

Does this sound continue like a roar or a buzz? Or is it simply a quick sound like a crack? I have heard noses with my SR-001 and SR-003 both and don't know if this sound is a fault or a "fart". Thanks

More great work reconstructing an old headphone. You should get a great price for those.

I watched it and enjoyed it as well.

Congrats! You will enjoy them.

I am not sure which forum to put this question, whether the headphone or amp section. Which electrostatic headphone works best with the SRM-T1S? I now have the KGSS and the SR-007 for it is coming. I also have the T1S and want to optimize it's musical presentation at a second location. I really don't what the time or money to play around with all the combination of these headphones. I am inclined toward the SR-404, any comments. This is after reviewing lots of threads and personal rankings. I prefer the sound of the SR-Gamma Pro to the SRX-001 Mk3 normal bias. thanks

The little box on the left is the Lavry DA10 and Squeezebox that is feeding my KGSS.

I don't know what others think about the Gamma Pro but I think they sound beautiful. They like power and with both the SRD-7 Pro/Icon and the KGSS they sound great. They did not sound as good out of the T1S.

The KGSS is in the house:

The KGSS is coming, the KGSS is coming; it is at my PO today. I will get it most likely Monday or Tuesday. Good news after a group miss-up on shipping. The SR-007MkII is coming as well and should be here maybe by the end of this week.
