Thanks for the advice purrin and everyone else.  I went to Radio Shack and got a bag of 3A 250V sloblo fuses, and my GES is working great again!  I wonder why the fuse went, as all the other audio stuff on the transformer is powering on and working fine.
 
jaycalgary: I found the 009s fatiguing to listen to over time on my GES, but I'm definitely in the minority.  The detail and speed are exceptional on the 009s, but it doesn't sound as musical as the 007s to me.  I have a hunch that I might be mentally dialed into my 007s, and if I lived with the 009 for a few months it might change?
 
The 009 is a tough one for me because it excels at all the subjects, but the overall composite isn't a winner for me.  Maybe the BHSE will change things.

 
I just got the 009 and the 727II yesterday. At first I thought they were missing some of the bass I heard when I audiotioned them with a RSA A-10 but after couple of hours they settledown and the bass response increased. Last night I listen to them for about 3 hours with no fatiguing at all.
 
I love the detail and soundstage presentation. The music comes from a very dark background like form nowhere and has a lot of air and separation beween instruments and voices.
 
What power cord and interconnects are you using? What is your source?
 
I listened to the 009/BHSE combo together with a very knwledgable fellow Headfier and both agree that the 009 sounded very detailed but on the lean side. IMO the BHSE is a better match with the 007 and the WES or A10 with the 009.

New headphones, or ones that have been sitting a month need
a day or two to charge. Fact of life.

Thanks Kevin. I am new with electrostatic headphones so it is good to know.

A better approach is maybe a warmer source and keep the BHSE in the chain. The BHSE is not necessarily a bright amp.

Might be but then I guess Justin selected the wrong source or cables in his setup at RMAF becuase that's where I listened to that combination. The only thing I am saying is that IMO and to my taste it did not sounded as full and rounded as the other two. Granted the source of the A-10 was a Boulder CD player and I don't remember the source of the WES but it was not as High-End as the Boulder.

I've been discharging my headphones after I finish listening, should I not be doing this? (I use them every day or close to)
 
I always assumed dust is more attracted to a charged membrane.

Bingo.  x3

He didn't say that I don't think, he said lean.  The Accuphase certainly isn't bright or lean.

Could you please provide technical explanation why? I read not long time ago that ones you plug headphones the stators  become charged instantly. thanks

Kevin or someone else can do the technical reply but I can say that is NOT true for the ESP950.  We plugged them in to the T2 the other day and they sounded completely incoherent  from power on.  After about 15-20 minutes, all was fine.  We actually thought something was wrong.

Was the amp just turned on? Class A monsters do sound better after some warm up. I experienced it with my Blue Hawaii, KGSS and other class A speaker amps.

Good question, I don't recall.  I'll have to recheck.  T2 does have a few bits in the signal path.  Thought I did notice a smaller effect w/ the E9 but it could just be the amp which makes sense.

"Stax ESTA4u speakers spotted on ebay"
I asked about these speakers before and seems either nobody really knows about them or really could care less about them. Maybe they are just to small. Last pair on ebay sold for less then what these ones are at now.

It is a 5 meg charging resistor on the stax headphones. 10M on the he90's.
The space charge takes a long time to distribute over the entire diaphram.
On new headphones it really can take a few days. On very old phones
it can take longer than a few days. The resistivity of the diaphram is
on the order of 100's of megohms per square.
 
If you charge them up, and then unplug the headphones from the
amp and don't touch the pins, they will stay charged for quite some time.
 
esl63's take a week to charge, as evidenced by the speed at which
the neon lightbulb blinks.

Hi Kevin, So is it OK to leave stax headphone constantly charged since I never turn off the stax 323s amp as it is a S state amp, unlike valves.. That way the 507 will sound its best at all times. However as  J Pak questioned... what about dust attraction? Any good advice? thanks. BTW.. The 323s and 507 is great. The 323s sounded even cleaner with greater dynamics than the srm1 mk2 pro. Also, the improvement from stax lambda pro to 507 is very audible., more bdy ,bass n transients dynamics all round.
