Hi,

Aren't these the people that used only "natural" insulators?
It was reported to be a fine interconnect made of OFC.
I wouldn't know what to suggest to you unless you could point to some consistent sonic flaws.

Razaw,

If I've got the right URl:

http://www.hewtech.co.jp/pdf/cable_do_3839.pdf

It says the inner insulation is "poriechiren", which I guess is probably polyethelene.

John,

I can't make much out of the pdf file but it looks suspiciously similar to a bog standard RG58 cable:solid central copper core,polyethylene insulator,copper shield and pvc sheet.
Impedance,I'm guessing,75Ohm.

Cheers,

Frank,

It says in English that it's available in both 50 and 75 ohm versions.
Probably isn't anything special.
I'll probably get a hiding for this; but what difference will 50mm of cable make?

John,

I missed that part.
50mm inside the player,you mean?
If it's in the digital section it should not be 50 Ohm,and I wouldn't loose sleep over it if its terminated correctly.
If it's in the analogue section and the user has ultrasonic hearing,err...he won't be listening to CD then,would he?

Cheers,

The Hirakawa cable has written on it TC-C I wonder if it means teflon coated. I wonder if replacing it with teflon coated silver military cable will make sens.

Razaw,

It doesn't say anything about teflon on the data sheet, just polyethelene.

Personally I am a cable sceptic. I just answered this one because I know a little Japanese.

Cheers,
