TDK BA200 - Appreciation Thread - Page 93

post #1381 of 1388
You might be able to contact Minerva and In-Earz--I think they've used the Sonion. I think there's another (Phonak?) that might also.

You might be able to check those and see if they have any.

I've read that many are quite successful in using the Knowles dampers to replace and to experiment. The only problem is that they are quite hard to get: I've got to pay 20€ shipping for a 1€ item, thats rough.

 

Here is the article where Rin tested different Knowles dampers, I'm sure it has already been posted some pages downwards in this thread.

I think the conclusion was to use the orange Knowles (3300 Ohms) with the right tips.

 

The filter on the BA200 is quite easy to remove. It's only a thin membrane that is attached to the red ring you see when you remove the dust filter. Just remove the membrane first and then the red plastic capsule with tweezers and you're done.

 

 

The Knowles are also used when experimenting with damping on the Shure SE535, there people claim that the Knowles filter themselves produce a clearer sound than the stock filters even when using the same impedance.

I got my TDK BA200 swapped for a pair of UM2 from fellow head-fier two years ago. I found the TDKs very delicate and sweet but the soundstage felt too remote for my liking. Not like UM3X at all as some suggested. Moreover, it requires bi-fiange tips for best sounding but those were too uncomfortable for me to hear over long period. I haven't seen them for a while in Hong Kong market it doesn't surprise me they could be discontiuned/out of production. 

 

EDIT: reading pages of the thread, I wonder if universals will always be an experience of YMMV

I had no problem removing the clogged damper and placing in the Shure SE530 damper which looks far more robust...but as i just had one SE530 damper the left iem still keeps the red Sonion damper and i'd rather have the same damper in each monitor (even if i don't seem to hear anything strange on the overal sound).

Hence where could i buy some Knowles damper?

Thanks in advance

You can actually just take a look at the Knowles site, they have a list of distributors for each region.

 

Mouser seems to be one option, you can choose between different dampers labeled as "Plug, 2.08 dia." from this list:

 

http://www.mouser.sg/Search/Refine.aspx?Keyword=dampers

 

This is the one to replace the original 2200 Ohms damper:

 

http://www.mouser.sg/ProductDetail/Knowles/BF-1921-000/?qs=sGAEpiMZZMuTkJYgZlQcSS8HGd2QVsfvts8N8qjTdbw%3d

 

They do look different on the small picture, but don't worry: if you look at the spec sheet you'll see that they resemble the form of the original filter, only that the outer shell is made out of metal. And you'll have to select the right Mouser site first, this is the Singapur version but there should be one for Europe/Spain as well.

 

Here's the list on the original Knowles site:

 Thanks a lot for the info.

 

I'll take this misfortune to try out filter moddings.

 

But i was thinking in starting with the  Etymotic kit of green (1500) filters & extraction tool (mostly for getting a cheap extraction tool).

 

FTR back in the day i took out quite easily the Shure SE530 dampers with the provided wax cleaning tool but in order to take out the clogged Sonion damper of the TDK BA200 i could only succeed with an allen wrench (after trying out every thin and long object i found at home). Needless to say the red damper came out absolutely destroyed.

 

On a side note recently i got a westone w30 and they use a red damper (where westone 3 one looked white). Wonder if that explains why Westone W30 puts out a little less volume than the old Westone 3 (Drivers being the same)...

The BA200 damper was quite easy to extract using the cleaning tool and a pair of tweezers for me, but mileage may vary.

The Knowles dampers will be far easier to remove because the metal casing is bent, giving any tool you use a lever to pull on.

 

Here is a very detailed description of the SE535 sound changes with all the different damper sets that are available from Knowles:

Also take a look at this chart from Rin's blog, you can see exactly how the sound signature changes:

Based on the experiences of one user in this thread the combination of the orange dampers (3300 Ohms) and either the Etymotic ER6i-18C or the Shure EABKF1-10S (Shure Olives) tips was recommended for the best technical sound characteristics.
