Default So why are Heatsinks so bloddy expensive???

Just feels like a scam to me. I mean Heatsinks can run in the hundreds of dollars for a pair, yet you can buy a $70 car stereo amp from the pawnshop thats not too much different in size, and the whole blooming top of the case is a heatsink. So why so much? I mean it's extrueded aluminum isnt it? I know some are machined, but I mean come on!!!!

He can't buy that $70,- amp because a chipamp has (practically) no heatsinks...

Go for an amp from Passlabs.
Most of them have adequate heatsinking.

Who's selling heatsinks for hundreds of dollars for a pair?

How 'bout $120 for a pair of these?

Click the image to open in full size.

Minus the amplifier of course.

Machined and anodized and subject to availability.

Well, I guess thats my problem is that to me even $120 a pair is too much, since I cannot believe they cost that much to manufacture and package. I'm probably way off base, but I just dont think they're worth it. And it sux, cause you have to pay to play, and you cant skimp on the sinks.

BTW those sinks do look extra sexy, LOL

Well the thing is that the companies that actually produce the extrusions haven't much interest in chopping them up and selling them as generic blanks, except for some of the small stuff intended to be used on a single device.

And they don't want to take a 10 foot bar and chop off a couple of pieces. They want to sell the 10 foot bar. And some of the bigger suppliers have higher minimums than that.

Lemme see what I can do for just a raw, cut and deburred sink.
