The cable between my Tyros 2 and the TRS-MS02 optional monitor speakers got damaged. This is a proprietary cable (combo 8 pin din and 1/4" to RCA).

I called yamaha parts for a replacement and they said that
1) The part was backordered for two weeks (that I can forgive).
2) The cost is $46 plus shipping and handling and tax.

That is price gouging to the extreme!! For a cable that costs them around a buck to manufacture.
I used to work for a car audio company. And we did not rip existing customers off like that. A replacement cable was generally around $6.

I am absolutely disgusted. I hung up the phone without ordering the part and will try using a standard 8 pin din serial cable available on Amazon for $2 (apparently mac computers use this connector). Hopefully they are wired the same way.

I'm sorry, but Yamaha is being very greedy here.
