I came across this, this morning:

2022 Golden Ear: Technics SU-R1000 Reference Class Integrated Amplifier

• by Anthony Cordesman

Technics SU-R1000 Reference Class Integrated Amplifier

$9499

Having said this, my final selection is the Technics SU-R100. Its phono cartridge optimizer is another demonstration of what digital correction and processing can do—even to the front-end component that most audiophiles treat as anti-digital. I think it does a very good job of getting the best out of a given cartridge, even though its “English” instructions have their limits. More broadly, it has one of the best-sounding digital amplifiers I’ve encountered and a very-good-sounding set of digital coax and optical inputs. Neutral rather than warm, it has lots of detail and really good dynamics for a unit of 150Wpc (8 ohms) to 300Wpc (4 ohms) output power. Also, it is a compact solution that offers the capabilities that normally require three separate components—no need to invest in interconnects between such components—and it is priced at a very affordable level for a design this advanced. 

Maybe this can help narrow down any decisions.

All the best,

Japan is 110V, 60 Hz west of the Fujigawa river and 110V, 50Hz, east of the river. Go figure. You can basically operate anything made in the US over in Japan without dire consequences but the same doesn't hold for the other way 'round. 

Having said that, any decent step down transformer should be able to handle something like the Technics SU-R1000. I wish johnsonwu the best of luck with his new Technics, and I envy the discount he got. 😄

All the best,

I have the Technics SU-G700M2 and would love to be able to upgrade to the SR-U1000 but I can't afford to. There's something wonderful with the sound Technics is getting these days. For me, it would be no contest, get the Technics.

All the best,
