GaN Class-D feature packed amplifier from GaN USA themselves limited supply!!!



I started this thread again, because of what the the old one turned into

Hi, here for $995 USD  is an integrated GaN Class-D amp with DAC!!!! all made by GaN USA, so you know it "should" be good. 🤞
(Could very well be the best of all GaN amps)🙏
(single private purchase only for $995 USD!!!, not available for multi purchase for commercial Class-D manufactures)

But you’ll have to put it in a box, comes with all you need, the amp and power supply, and dac??!!!
(if you can build simple kits you can build this, would it quite simple to make up)

You have with it:
1: Volume control
2: 3 x switchable inputs
3: 2 x Analog stereo inputs rca & mini jack
4: 2 x digital spdif inputs, optical and coax (yes it has a dac in it too)
5: And this is real neat, user variable negative feedback!!! for those that don’t like too much for the sake of "better" measurements" and want a more organic sound, all for just $1.3K
6: Laptop configurable "Audio Canvas III" plugin software via the DSP Scamp connection for many configurations

Doesn't matter now, as Gan are out of stock of these now for 36 weeks.

I'll re-introduce then.
Just simply stating fact.
"twisting", is the word that comes to mind, because of ulterior commercial motives.

You aren't serious are you?
Deadly, sunshine, to someone that says this
" Class D amps can sound good, you just have to put a tube dac and tube preamp in front of them."😂

The thread derailers are out yet again.

Ok I’ll bite, let see what your Class-D can do tested by Amirm,
and if it can maintain full power into 4ohm continuously when it comes.



For those that wish to know these are the specs from Gan themselves, on this Class-D
Evaluation Board Test and Validation
The initial Evaluation Boards were tested and validated using industry-standard measurements, with recognized techniques and equipment. The standard set of industry performance and validation tests were run using this Test Bench. Performance Specification Testing
Power Output (200W into 8 ohms)
Power Output (400W into 4 ohms)

Following are the results of both the initial Characterization that was performed on the Class-D Amplifier platforms. Unless otherwise noted, the Characterization was performed under the Power Supply conditions that allow for the specified Target Market specification of 200W/8-ohms. This requirement resulted in Power Supply Voltage rails of +/-32VDC. This selected Power Supply definition provides up to 200W of clean power into 8 ohms, (as captured in Figure 5.1 below).
Figure 5.1 https://ibb.co/Jm9vbG5 with user switchable low or high feedback
The owner gave it to Amirm for testing set at low, high would have measured far better in the tests.

Amirm: "his focus was to keep the level of feedback low to show the advantage of the GaN transistors not needing much. He was not aiming to produce the best performance possible. Personally I wish he had targeted that, given that is what we like to see here."



And yes one thing the detractors got correct, more power can be obtained with added heatsinks and a higher voltage smp later if an owner needed more (I believe this has more than enough).

But I’ll still say like any Class-D, it/they are not for the 0.9ohm EPDR load that Wilson Alexia’s and others present especially in the bass.

Also they still need what Technics did with their SE-R1, and raise the switching frequency from 600khz to 1.5mhz so the output filter can do it’s job of filtering it out so this sort of 70 degrees of phase shift is not in the audio band. https://ibb.co/LpMkm8Y

There are other retailers they were sent to though, even cheaper at $940!!!! at bottom of this page.

For those wanting one, here’s a place (subsidiary of Arrow Electronics) that has 5 of them, and they’re cheaper here too, only $940!!!

There must be others as GaN has about 50 outlets world wide on the GaN where to buy page, bottom of this page. https://gansystems.com/where-to-buy/
