If I’m reading this correctly, the best way to make GaN-based amplification to sound more tube-like is to build the components into a tube???

BTW, again no rating into 2 ohms.


Given the target market, you can't fault someone for making it look like a tube amplifier. Can't comment on the 2 ohms, or the sound, but fairly sure that clear acrylic cover would not cut it as a required fire barrier required for AC products in North America.

I think George was referring to me when he said a member here who changes the Mosfets for Bi-polar transistors.  I agree with George on what he is hearing in sound differences between the designs.  This came about as I repair Counterpoint power amps which used mosfets and then Mike Elliott redesigned the amps because he could not find the Mosfet replacements and then changed the design switching to bi-polar transistors.  For the Counterpoint amps you can almost swap out the mosfets and install bi-polar transistors with a few changes and bias adjustments.  Since we repair so many of the amps, I can compare the sound to one another.  We now build our own amps after the new design that we implemented when we completely rebuild the Counterpoint power amps point-to-point wired basically using the chassis and the transformer so they are no longer Counterpoint amplifiers.

You really do  have to have a trained ear to hear the differences especially when you compare them side-by-side.

Happy Listening.
