Technics SU-R1000 a new Class-D GaN Technology integrated




Maybe one to look out for.

There’s a new approx $10K integrated Class-D from Technics called the SU-R1000 Integrated Amplifier around 22 kg, 150w-8ohm and 300w-4ohms, would have been nice to see what it could do into 2ohms
.
Said to have many of the GaN Class-D features of the far bigger SE-R1. But nowhere yet can I find if it uses the 1.5mhZ switching frequency that "makes" the SE-R1 what it is.

Also it uses smp power supplies, even though it’s 22kg, Unlike the SE-R1 at some 60Kg because of it linear supplies.
No reviews or measurement tests as yet for this one from Technics

Once I find a review and hopefully bench test done, I'll post them up.

This one really looks the affordable goods using GaN, if it also used 1.5mhz switching speed, like the SE-R1.
If anyone find more info on this please post it up.
I also found, I think it has a built-in DAC and MQA (not that mqa means anything to me) as well MC MM Phono

Based on a graph on Technics own website for the much cheaper SU-G30 that reads "1.5 MHz Operation", there is no reason to think this new $10,000 integrated is not operating at that speed (or faster?) IMHO.  

I will also be keeping an eye on this new integrated amp.




I think we already found that the SU-G30 it was not 1.5mhZ switching speed just after it was released, but around the 600khz that most uses today.
Can you put up a link to show the 1.5mhZ switching speed

PS: Sorry, you maybe right, that could have been the SU-G700 that wasn’t 1.5mhZ, maybe the SU-G30 is? And if so then the SU-R1000 would have to follow also, they’d be mad not to.

There is a graph at 
http://https//www.technics.com/us/products/grand-class-g30/network-audio-amplifier-su-g30.html
near the top in the JENO Engine section  The graph is labeled "Output of G30 JENO Engine".  And in the graph it says 1.5 MHZ operation.  I am not totally sure that is the switching speed though.  Technics just mentions "high speed switching" in other places without explicitly stating the actual number when talking about the SU-G30's GaN-fets.


Yes that it, when I queried Technics on it with the SE-R1, and one of the reviews also backed it up.
Wow that means the SU-R1000 should hopefully have the 1.5mhZ switching speed also, when it comes out in mid/Feb 2021

They must have listened to what Cyrill Hammer designer of Soulution Audio had to say about Class-D
"if you want to have your product performing at the cutting edge it is not possible with today’s known switching technologies. In order to come close to the performance of the best linear design we would need high-current semiconductors that provide switching frequencies of several MHz or even GHz."
