Same here, diamond. Tearing usually happens when you don't have enough speed.

2389 is usually tweeter, 2354 is vented and better as full range.

Just open the other iem and copy it...

Has anybody noticed difference between ceramic and tantalum? Some people insist on using tantalum?

Direct out is cleanest (I did it before dminor). You do not need to unsolder anything with direct out, only cut the out pins connection to board. Adding caps will change sound slightly. Though you will need amp with caps on input.

Used dry rub-off decal paper. Will printed colours fade over time?

Got my DX50 in November 2013. At the end of last year left side started to loose signal. Month ago I had to open and resolder the socket. Now works as new.

What do you mean? GK is dual... http://www.knowles.com/eng/content/download/5920/103132/version/2/file/Receiver+Datasheet+GK-31732-000.pdf

  Use GK-31732

  It comes in several thicknesses. I will let you know how it goes.

  No, not expensive. Any material will do as long as it can stand a bit of heat and is not soft. Even the shell out of acrylic will do. The mold does not get heated, only Mylar. Only heat the mold gets is from hot Mylar once vacuuming.

Let me explain what I mean: At work we sometimes use Mylar for vacforming. It is BoPET. "BoPET (Biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability...

How about vacuum forming the shells? Brainfart?

No one?

I'm thinking of ordering Sonion drivers.. Still 5 drivers minimum of any type? 20 all together? If so, which ones are worth ordering? Planning to mix them with Knowles. Looking for that Sonion-only sound...

  @DMinor Are you going to tell us about your latest find? These mystery green super/ultracaps? 

Have tried about 20 different capacitors. Only 1 pair was supercaps. At the moment I use film caps. Mundorf silver/gold for lod cables. Are the green ones Ioxus?

What make are the green caps? Tried some supercaps (white) with no success... Gave up.  I got Objective 2 kit for Christmas. Took me half a day to put together - loving it. Happy Holidays

Planning to upgrade from Vsonic R07 MKII. What do you recommend?  I'm not a basshead but dont like total lack of it, like brainwavz b2 mentioned above. Previous page. For that reason I prefer dynamic. If there is a balanced, better in all aspects? Maybe? Budget around £300 / $500 Thank you

  Large mp3 collection? - go for imod.  If you plan to rip cd's in flac then there are better options: AK, iBasso etc. I have iBasso DX50 and few rockboxed imods. For mp3 imod is better imo. But when it comes to higher resolution files, it can't compete with iBasso. 80Mh vs 1000Mh cpu!

  Got some Mundorf silver/gold wire thinking... well, not much A few days later found: http://eandt.theiet.org/magazine/2011/11/believe-in-better.cfm

Thank you. Where did you find side exit connector? Qables don't to sell them any more. 

About 7 months ago bought: http://www.ebay.co.uk/itm/MUNDORF-Silver-Gold-LOD-for-IPOD-IPHONE-/281206005481?pt=UK_MP3_Player_Accessories_Cables_Adapters&hash=item41792f1ee9       Now I can make this (with Wima 4.7uF 63V 5% inside) for around (depending wire) £15 Probably less...
