The Truth about Modern Class D

I’m not talking about wattage Ralph, and you know that very well, give up and try not to go into product protection mode, when ever GaN is mentioned.

This comment does not make sense when compared to

The ones around now using GaN’s are either dinky little office type class-D’s or expensive ones that haven’t utilized the technology as far as Technics did.

'Dinky' in this part of the world means 'small'.

And since you chose to make the usual ad hominem attack, can you get it that we've been working with GaNFETs in most of our prototypes except the very early ones? Why not, they're quite inexpensive!

Like I said you know exactly what I mean, and yes it means the same in Au. I’m talking about dinky ones the size of cigarette packet, some that can do 120w sometimes with external wall wart smp supplies, some that are shilled on these Audiogon pages. I would bet the 54kg Technics SE-R1 would eat them alive same wattage. at 8ohm

Maybe something you don't understand is that the size of a class D circuit board says little about its power. They have to be small in order to keep radiated noise down. So traces are short (less inductance), there are usually at least 4 layers in the board and so on. So a board that is the size of a pack of cigarettes is that way even if it can make more power. Most circuit boards (modules) employ ICs to do most of the class D functions- comparator, drivers for the outputs, high side switches and so on. This helps them be more compact and so less noisy. Our prototype boards make 100 watts and despite being relatively discreet (no dedicated chips) its smaller than a pack of cigarettes too. That's just common sense on the engineering side. I'm sure the actual Technics amplifier circuit is quite compact as well- my guess is that because of its very high switching speed, its even more compact!

Ralph you've been in the sun too long mate.
I understand fully Ralph what you are saying to me, two GaN amps below the same 8ohm wattage.

You are saying this 0.9kg 150w Gan amp

Will not be shamed by this Technics SE-R1 54kg 150w GaN amp

Sorry Ralph pull the other one it plays jingle bells🤦‍♂️

"....it plays jingle bells."  Damn....how tragic.
Hope your voice survived....

Well, until someone somewhere puts these two competing amps between a pair of quality speakers with ditto level cables....and source up to par to the task....

It remains conjecture, and opinion.  The 'referee' has already rang the bell once, with a warning to the combatants....

It's still summer in AU...right?
