Class D

To others that care about these forums.

All we have are manufacturers and their shills, with incessant agenda to get he ball rolling on their latest class-D products, and they use these forums to slyly advertise what they have coming up for sale, and will stop at nothing to counter anything that may effect those future sales.
See the immediate angst cause to them with the professionally ready made diy GaN Class-D kit I put up above, which is probably better than anything they could do.

One here especially put rubbish on the new GaN transistor technology way back when I showed it to all here, and he said it has no advantage over the Class-D technology used.

But now he’s has changed his tune and is actually pro GaN transistors, funny what the mighty $$$$ brings out in people. Like I said they are just here to slyly advertise their goods. You can’t believe them, especially the fusers!

At least companies that use GaN like Orchard Audio, AGD ect don’t come here behaving like them.

Cheers George

Here are some interesting developments....

1. Class D audio (under the Premium Audio name) will soon be releasing their "baby" GaN amp.......stereo, 150 watts a channel into 8 ohms, balanced and unbalanced inputs for a mere $699.  100K input impedance.  You will see a tiny bit of info here....wait for the second slider to load to see the pic

2. Orchard Audio is releasing a higher powered version of their GaN amp module.  You can buy the module fully loaded or you can just buy the board and buy all the parts and stuff it yourself.  This new 250 watt a channel module has higher input impedance (44K balanced) and higher gain then before so makes it more universal.  The unloaded boards can be bought for $100.  The stuffed boards can be purchased for less than $1000 the pair (till the early bird sale goes away).  This would be way better than the eval board put out by the GaN companies.....The Orchard amp measures and sounds very, very good.....800K switching and very very little phase shift.

The phase response and other measurements of the earlier less powerful module can be seen at the bottom of this page.

Look at that, no phase shift ...

The low frequence phase-shift is measurement artifact.

Folks,In the interest of staying on course, can we ignore george and move on? Would like to hear more on the new amps using either Purifi or GAN technology.

At least companies that use GaN like Orchard Audio, AGD ect don’t come here behaving like them.

George's complete lack of self awareness to his own behavior is astonishing. Absolutely one of the worst offenders. None of the others have the product they sell as their avatar. He promotes to sell with every single post.
