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

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."

I would be interested in this product.  Looking for a great integrated into retirement.  Hope it delivers.

I'm pretty sure the figure of 750 to 900 kHz, less than 1 MHz, was written somewhere in relation to the G30. I remember being disappointed that it's not the promised 1.5 MHz, but also thinking that maybe it was good enough. Recall that I used to own it. Now possibly it's 50W into 8 ohms wasn't enough to really get my ProAc D30Rs into the zone but I remember being left cold by the sound which I thought was sterile / boring. I also thought the MQA didn't really sound any different through it. It had an internet radio function which was cool. I also remember being disappointed by various problems the built-in UI had, but those were ultimately manageable. I'm sure it's been fixed by now.

I would like to hear the SE-R1 if I can find a dealer somewhere I can listen to it.

SU-R1000  might be just the ticket if the promise of 1.5 MHz bears fruit.


Here’s something interesting, they gone all out could be a good sign, it uses a clock that is battery powered, must be rechargeable with it own charging system..

  • Thorough noise countermeasures improve clock accuracy and reduce jitter.
"Battery Driven Clock Generator & Low Jitter"

"Battery Driven Clock Generator" is used for the power supply of the clock circuit to improve the accuracy of the clock, which is the standard of operation in a full digital amplifier. By using a battery as the power supply for the clock circuit, the adverse effects of power supply noise on the clock circuit have been eliminated, enabling highly clear sound image localization and clear spatial expression. Moreover, the clock itself has adopted a low phase noise type, and has been thoroughly improved in accuracy.


It also has balanced input for the phono stage, for the T/T lovers

And it can be used as a Pre-amp only or Power-amp only, or Integrated

And the dac has 6 digital inputs in 3 different configurations, using the (Asahi Kasei Electronics) aka AKM top D to A converter

This is a real "Swiss Army Knife" of Integrated Amplifiers
