In search of info from the technical guys

So, they probably buy the chip and make their own power supply for it I guess.

Here's something I found on the 'net about the Class D amps in Golden Ear speakers:

Lots of different class D and OEM's, and always someone around who tries making a new one.
Pascal, Hypex and ICEPower are among the most common, but Crown, Yamaha and NuForce make their own. Texas Instruments makes a variety of IC's to fascilitate their construction, now ICE is getting into the IC market too. I think for NAD, Hypex created a special hybrid I haven't seen elsewhere.

With all such products, but especially with Golden Ear, I would not focus too much on the tech but the results.  Always fun to talk about technology but in the end it's the implementation and our enjoyment that matter.

Best,

Thank you for that, it was exactly what I was looking for!!

The chip used isn’t terribly important for a subwoofer. The problems with Class D show up in the treble and normally its most obvious to those with younger ears.
