GaN based SU-R1000 Technics Integrated Class-D, review by TAS

George, you are aware that AGD's Audion first gen is "only" 400kHz and is considered to be an excellent product? Their second gen is up to 800kHz I believe.
So, let's stop touting 1.5MHz as the requirement for excellence. Perhaps it is for other designers but Alberto knows more about GaN's than others.

Well for those that know it’s not good to put all that wattage, current, signal etc etc through those tiny touch contact tube pins, they will be a problem after a while. Even the designer said the tube thing was a bit of advertising gimmick in an interview.

See even he knows that the higher is better.
As the SE-R1’s at 1.5mhz!!! is minimum, to have close to zero phase shift back in the audio band.
As this Hypex at 600khz shows has (red trace) https://ibb.co/2thS6y2 with 70 degrees!! phase shift at 10khz! and still 50degrees of of phase at 2khz!!!!!
>2mhz in the future will be the best.

I have a good friend who has listened to the Technics  in depth 
And it is very good but felt his Coda CSIB integrated was more complete in several areas ,in other systems they may like the more nimble Technics, the Coda uses The Latest Mosfets,
FETs, gan are the latest fastest FETs , and the Coda also uses 40 Bipolors on the outputs day Huge 3kva potted transformer , I myself bought the Coda and just installed IMO the world class Latest Jupiter waxed paper Copper foil 
capacitors for the Class A  preamplifier output section. It is very good it will compete with top separates in the $10 k+ range,which says a lot. 35+ years  in business ,10 year warranty,and           Made in USA 🇺🇸 

George you have been critical of many designers, engineers, builders and brands.  What amps, preamps, DACs have you designed built or what patients do you hold?  Just wondering before I invest in my next piece of audio equipment.
