Hi Indra, welcome back. I wouldn't fret too much about spending a ton of $$ on a replacement cable for the 600s. I'd order a stock HD650 cable (assuming you still can) and use that. It's a nice, decent qualitiy cable terminated with a 1/4" plug and easily adapted to balanced drive if you really want to. The best thing is that it is non-microphonic unlike most of the aftermarket/DIY options. Actually, I just looked at the 650 cable is still available and a meager $14 + shipping. If you can't order it internationally just shoot me a message and I'll get you one and forward it along.
