An update on my B&W Electrostatic speaker Repair.
Symptoms - One of the ESL Panels was not as loud as the other.
I switched the ESL panels and the problem moved over to the other side. This told me it was a panel problem. So I took the ESL Panel off and started the process of removing the ESL panel parts.
The way an ESL works is actually very simple when you break it down. There is a membrane - mylar that has spacers on each side of it. On either side of these spacers are the stators that take the voltage and conduct electricity < > making the membrane move / vibrate. This creates the sound.
In the top link the picture on the very right shows the stator on top, then the spacer and the membrane itself which underneath it one will find the other spacer and stator.
Much to my surprise when I removed the parts I found what is in the picture on the membrane.
Debris larger than dust. Maybe from a house project entered the ESL Panel when it was charged up. The bottom picture shows my attempt to clean it. The debris on the mylar was preventing full movement. Other than that the mylar was tight and no holes or damage from what I could see.
The speakers had been repaired prior to myself owning them. I remember when I initially set them up, I experimented with external tweeters. But I had the Quad 57 project going on at the same time so didn't get too detailed with them. These speakers do not need external tweeters. The one speaker was throwing the balance off.
The bass can be tuned easily by removing or adding cabinet stuffing.
CD player laser module replacement easy ?
The prevailing message in my system description is that. ... the "Gear" is just a means to the end. Blessed is the music lover that reaches the end point without spending thousands. If this person frequents Audiogon .......good luck to you. :^)
Some hindsight in reaching the end based on my personal experience.
Once you have a 2 channel stereo system "kit" that is at a point that sounds great to you in your room. Move that kit in whole including all cabling to 3 or 4 different rooms and see what happens.......:^)
The room ......is indeed the Elephant.
Quad 57 Room B Subwoofers Result
I found Two New Old Stock (NOS) - Dynaudio Acoustics BM12s in a recording studio. Never out of the boxes.On paper for my needs they are; 18hz - 60 hz with 4th order Linwitz- Riley crossovers.
So the Dynaudio BM12s crossovers have a flat response where cutoff is applied. This, plus being a sealed box design made them appear to be a really good match for my Wayne PK Quad 57's. Quick and no cone bass past 60 hz. They house 250 watt amps @4 ohms which from the size of the heat sinks I assume is Class A/B. Most of the other subs I looked at were high wattage Class D designs..
The numbers matched up, so I made the drive out there. I brought the two home and tried them out. I did find them very punchy, clean, and quick. They go really low and keep up with the 57's on kick drums and other low bass. A good ergonomic match (to my eyes) with my raised Wayne PK Quad 57's. The subs are placed under them with the woofer cones forward of the actual Quad 57 panels - for now. This sets the sub phase alignment at "0"
here is what the set up looks like.
I am not able to preview a post on the system thread. if the direct link doesn't work see the last bottom picture of my virtual system page - the one to the right of the Bengal kitty :^). .
The Dynaudio's use a thick credit card sized remote control for configuring them. ( don't lose it ).
A little strange how all this came about. This was a good 6 month plus search. The Dynaudio BM12s were a real dark horse that just appeared out of the blue toward the end. For those following, the other subs I was seriously considering were JL Audio, REL, Rhythmik and Seaton. Rhythmik and Seaton are very hard to find used in Canada, and I was not willing to pay 30 points on the Canada US dollar difference, plus shipping, customs and duties on them for new ones. I did manage to find a used Seaton Submersive for sale; but when I went to hear it, I found out it had issues with the original smaller Seaton amp it came with clipping. This was revealed to me by the owner who had the smaller amp exchanged for the larger Seaton amp. But this meant the condition of the driver's voice coil was suspect. I passed on it. The only REL sub I would buy are the older ones Made in the UK. This means their physical condition would be ?? and repairs would need to be made at a third party repair shop. So knowing the previous owner/s is important
The Recording Studio gave me a warranty on the two NOS Dynaudio BM12s. Room B is pretty much complete now as far as gear goes. Maybe I will I start finishing touches on the actual room.
Koaltar needs a pat on the head (if you can get to it), and a good scratch behind the ears
Will need more input on just how great the improvements are on the push-pull amp
Banquo363 - And those 2 large gauge looking wires that appear to be going to the rca inputs? Noise reduction mod? No idea.
Slaw - I recently purchased a three pack of Shunyata DF-SS risers to go under my interconnects leading from my preamp to my amp. I placed these on pieces of pavers I had left over from my sidewalk project. I felt the increase in height would help, along with additional isolation.
Banquo - I don't have a cd player hooked up to my system (there are not enough hours in the day for both vinyl and cd)
uh...could you pass this note along to your wife:
There is a guy in S. Cal. who will pay handsomely for the Holly Cole Trio's Girl Talk on vinyl. Please do 'search' and contact me once found.
It's a vinyl bargain hunter's paradise: I once found wagner's entire ring cycle (16 records) for $4.
Banquo363 Evidently many people only pretend to like opera because virtually every one I have bought has looked unplayed.
I didn't know you liked opera?!
I'd put the Mahler and the Beethoven piano sonatas first on the clean cue.
I can relate to what you say. I have 5 rooms each unique continuously enabled for good sound and 3 different headphone setups
Give Koaltar a big hug from me, I wish he could visit!
Thank you for your kindness.
I don't understand, why do you want to put the motor on a battery?
My husband never proposed this fitting , and more he did not want to let the turntable be put on battery.
This opportunity was the fact of one of our dealer in GB .
Please accept my best regards.
The Tannoy sub is the best match I've found yet for my HPD's.
It seems discussions about subs is almost a taboo subject, like a dirty little secret we won't discuss in public.
Halcro - If my wife is going visiting for a couple of days I plug the 57's in overnight.
If my wife is going visiting for a couple of days....I fill the bath with ice and call Susie to invite the gang over............
But hey....vive le difference....!?
even if they don't become obsessed with it.
So how does it sound ?
She might as well have sent it to me!
you're all over the top audio nuts.
You didn't state what the giant piece of wood is for, did I see something about a dock?
The DAC8 uses the same digital chips that are used in the Reference DAC. The REF DAC has a vacuum tube audio output instead of a solid state design.
Please see attached file for more information.

Did the big smoke yield rewards?
The TASCAM DA-3000 is an appealing product as it features BNC SDIF-3 inputs and outputs...one can pass native DSD signals if one prefers a different DSD DA converter than what is available on the DA-3000. It is DSD128.
DSD128 is very good...haven't listened to DSD256, yet.
Should you have the opportunity, audition the non-oversampling, i.e., NOS, DACs from Audio Note.
I probably listen to more CD's than vinyl, mainly due to not being in the mood to go through the motions required for vinyl. In other words, I'm lazy.
You state that on your Technics SP-10 set-up, that the spindle resonates at 5-7hz. Correct me if I'm misquoting you or if I'm totally wrong. How do you come up with this measurement?
I tried your test and I get no noise except a little buzzing from the tweeter--that's always been there, even when I had shielded cables.
Are your wires separate strands? Mine are twisted together.
Do you have time for a job?
2-17-14: IslandmandanLook forward to your impressions of the album Dan.
Chris, "Gravity" is on order from CD Universe. Getting ready for some finger-snapping and foot-stomping!
I don't believe that the B&W 801 with its low ohm lmpedance would be a good idea with a SET amplifier.
That Natalie Merchant has an unforgettable voice--except that I forgot all about it. That is, until I heard the first few notes from your link. Then the memories...
Of the artists you listed, please name your top 3 records.
When I bought my house 3 years ago, I hadn't caught the audio bug yet, so did not take it into account.
Banquo363 - and it tends to get louder as the evening wears on.

seriously contemplated acquiring some 800's -- they would complement the Bevs and DALI :-)
Banquo363 ... took 5 guys 9 hours to assemble the 800's!
800 Setup from Stereophile Review.
If you're the type of person who loves to tinker with your car every weekend, and don't mind having to remove half of the engine in order to change the plugs, you'll love deciphering the 800 owner's manual and assembling these monsters. But if you're like me, this could be a big pain. The 800 comes in six large crates, with no indication of which to unpack first or where anything is supposed to go. The manual is confusing, and often incorrect, which may make you question your ability to read English ("this screw just doesn't fit into that hole!"). Luckily, in my case, Victor Goldstein (consultant to B&W), Chris Browder (Executive Vice President of B&W Loudspeakers of America), as well as two members of our musicians' listening group (Al Merz, Ed Kelly) came to the rescue. Victor had set up several pairs of 800s before these, and knew pretty much what to do, while the rest of us looked on in utter disbelief. I recommend that at least two people be available when you assemble your 800s (lifting the midrange/tweeter and upper woofer modules into place requires a combination of brute strength and finesse); better yet, let your dealer do all the work. It took five of us the better part of a day (nine hours) to unpack, assemble, and position my review pair.

They're very funky looking.
We are proud to offer this unique warranty due to the virtual indestructible nature of Acoustat panels. Acoustat guarantees our electrostatic panels against defective materials and workmanship for the life of the product.It goes on to say the interface is warrantied for 10 years.
RichardKrebs - I wonder if the "Hi Fi" effect you describe is an artefact of the delay network used in the Spectra's. A lot of extra components are used to create this.
