  Thanks - but does it look "metallic" like in this photo? http://i58.tinypic.com/255o12c.jpg 
I know it is really silly to get one specific type of cable - but I've always thought that it looked amazing.

If you are willing to pay the price, then go for estron wires, that's what you are looking for.

The gold is the real deal. Silver and black are from eBay.

anyone can help soldering four wire cable to 2.5mm four pole jack for cayin n5 balanced? I just need to figure what cable goes where? I have occ silver plated four wire cable with 3.5 3 pole

Anyone know if this is a sealed chamber thereby doing away with the sticky inhibition layer?

From the pictures it does not look like a sealed chamber.
May I ask what the sticky inhibition layer is?

When you cure UV acrylic in open air, you get a greasy/sticky "inhibition" layer.  Some professional uv ovens like the Dreve unit a few posts up, remove oxygen so you don't get that.

I think there may be a misconception about how "removing oxygen" actually works.
To remove oxygen you need unit like Dreves Polylux 1000N or Eggers EL1+N - the "N" stands for Nitrous. Those units operate by injecting N into the curing chamber, replacing Oxygen as oxygen is responsible for inhibitation layer.
It's nowhere near what can be considered as DIY equipment. You need a licenced professional (at least in Europe) to connect the gas bottle to the curing unit. N bottles are 1. hugh and heavy 2. very very expensive. 3. could be deadly when mishandled.
Post curring solutions from Dreve/Egger will give you perfect results just as if the shell was curred in N atmosphere.
It's not worth risk or cost for small projects.

Also most dental polymerization chambers/ovens only direct uv light downwards, also with limited reflective interiors as most dental procedures will need solid polymerization or single layer polymerization. Not hollow meaning they do not us a uv blocking plate. Just food for thought, I too looked into dental cure units.

Lot of iems and ciem use DTEC but I dont find mention of it on Knowles pro audio website also legendary ED29689 is missing. Are these drivers now discontinued ?

Am I wrong in thinking that resistor polarity doesn't matter and capacitor polarity does?  Is so, does the positive end hook up the source/connector or to the BA?
 
Thanks

with ceramic cap it doesn't matter, for most tantals as well (i think).

Here is a pic of the Savant clone I've been working on!

May I ask what it consists of?

Knowles ED29689
1500Ω damper
20Ω resistor in series
2mm/3mm tubing length

Knowles ED30761
2200Ω damper
1.5mm/5.5mm tubing length

...could be wrong though.

I can't find any spec sheets for that ED30761 though.
The ED29689 does look kinda "bad" though. But I guess it is being used as woofer here so perhaps the region the datasheet don't show is good.
