Default Help for MUSES 72320 DIY kit

Hi all,

I was planning and looking for a volume controller and I ran into the DIY module of MUSES72320 that you can find in the following link:
MUSES72320 電子ボリュームキット: 組み立てキット 秋月電子通商 電子部品 ネット通販

Unfortunately it's in Japanese and I only could read it through Google traslator.
However, looking at its characteristics, it seems:

- equipped with well regarded Muses 72320 and with volume controller through the installed PIC12F683SN and related incremental encoder;
- small and suitable for many DIY projects;
- well engineered and based on Muses' datasheet;
- it has possibility of changing the output opamp and of playing with it;
- quite cheap price: 4200Yen ==> 29.5E ==> 40.5USD.

I'm asking for the help of any member (Japanese ?! :-)) in order to understand if:
- Has anyone ever tested one of them? How does it sound?
- do I correctly interpret its characteristics?
- are all components I've mentioned included in the kit?
- is there any possibility to buy it outside Japan? I couldn't find any email I could write to in order to ask for some info ...

Any help would be appreciated
Thanks

I bought some with the very friendly help of a Canadian living in Japan.
It is a nice volume control!
I used it without the OPAmp. In this case you have to bridge some connections on the board and to short some others going from the Muse to the OpAmp to ground.
The sound is very good to my ears, much better than the DS1882.
Detailed and it has real slam in the bass!

Thanks for your info. I noticed the Opamp isn't included but it opens the possibility of many different tests.

I heard the Muses 72320 is a very good chip .. now I'd need some more help on how to buy that kit ...

The shop selling the kit has no Paypal, no credit card paying and no email contact possibility, it seems to be not so usual in Japan.

So your helper has to pay by his own bank account or cash on delivery.
