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




After their unobtainable and unaffordable ground breaking 1.5mhz switching speed, Technics SE-R1 GaN Class-D power amp, this new offspring integrated has finally gotten an in depth review.

I had high hopes for Technics "fully optioned" SU-R1000 integrated, "looks" like my hopes could be founded, here is the The Absolute Sound’s 7 page!!! review on it, enjoy.

..and yet the reviewer didn't note:
1. What music he played.2. How the amp specifically performed with that music.
3. What the rest of the system was.
and the most important spec for George: switching speed!
This is a seriously lacking "review".
Finally, another Class-D amp that can't perform below 4-ohms and at $10K. Pathetic.


Don’t think I ever said it had 1.5mhz switching speed??, just it’s big bro the SE-R1, I seriously hope it does too. As 1.5mhz switching speed is far better than 600khz, as then there’s no 70 degrees phase shift (https://ibb.co/2thS6y2) then from 1khz to 20khz in the audio band.

And I’ve always maintained they (all Class-D’s) have a problem driving speakers like Wilson Alexia into very low impedance’s.

Yes, another nothing review.  "  It has notable competition at its price range"......then says nothing about its competition.....so, how do we know how it sounds without a reference.  Just another money making review.  Rave and do not compare......then the advertisers are happy. 

I am sure it is very good.....but how good?  you cannot tell a thing from this review.

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.
