The real test will come with a Strereophile review and bench testing which will give the best insight into this very advanced designed Class-D amp that uses the newest GaN Technology.

Technics SU-R1000 a new Class-D GaN Technology integrated
Here’s another video review on the "GaN Technology" Technics SU-R1000 vs the NAD Master Series M33 (which uses the Hypex N-Core class-D modules) Seems they both prefer the Technics SU-R1000 in the upper mids highs range. This "could be" because of the 1.5mhz (3 x higher) switching frequency it’s said they use like in their flagship SE-R1 poweramp. Which takes class-d’s normally used 400-600khz switching frequencies output filter’s negative effects well away (by 3 x also) from the audio band, without having to use any other "alternative" fixes to cure the problem that "could" also have their own detrimental effects. https://www.youtube.com/watch?v=x2rzllFT6S4 Cheers George |
Technics SU-R1000 has hit the Stereophile headlines. Must be due soon for release in the US for the retail sector.. https://www.stereophile.com/content/technics-presents-discussion-their-reference-class-su-r1000-digi... Cheers George |
Interesting online comparison to pass some time. Recorded through some good flagship stand mount speakers Pass XP12 $5,800 pre with Bryston power 4B-SST3 $5,695 https://cloud2.alpha-it.nl/index.php/s/QNsykngkykBffN2 Technics SU-R1000 integrated $9,500 https://cloud2.alpha-it.nl/index.php/s/5rp6XMexDKetA59 He stuffed up the titles just play the middle one on each Cheers George |
Here something that was just released. The technics "white paper" on the SU-R1000 https://valueelectronics.com/wp-content/uploads/2021/04/Technics-SU-R1000-WhitePaper.pdf Cheers George |
Like I said take another drag. To others here that wish to follow this new what "could be" the new best buy integrated kid on the block. This could be good to follow for all the vinyl crew, with the phono stage analyzing system with calibration record that comes with it. https://www.youtube.com/watch?v=xd7as68ccFg Cheers George |
For someone who preaches peace/love/woodstock all the time, you sure know how to go totally sour and bitter with things that don't even deserve it yet at every opportunity you can. Chill bro take another drag. This "promises" to be a very good integrated and is way too young yet to be reviewed by anyone like Stereophile etc, it will soon. So lay off the aggro on it till things get done in due course |
jwcondo It does indeed use the 1.5 mhZ switching frequency WOW!! That’s the only confirmed one with "1.5mhz switching frequency" beside the mighty $20k+ Technics SE-R1 and they "say" also the SU-R1000 integrated has Can you reveal where you got this info? as I looked everywhere. Cheers George |
Here something from HiFi Blog on the new GaN technology Mytek Empire monoblocks, it’s got some get up and go into 8ohm and 4ohm. Would have been good to see the 2ohm figure though, to see if it starts "wheezing" into it, or if it goes up substantially again from the 1000w 4ohm figure. Mytek EMPIRE monoblock delivers no less than 1,000 watts of power to speaker systems with an impedance of 4 ohms. If the speaker systems have an impedance of 8 ohms, there is still a whopping 500 watts available. Cheers George |
It’s vinyl/stylus/cantilever/alignment/generator interaction channel cross talk on phono cartridges, nothing to do with differentially balanced circuit or wiring or not. https://sonicpurity.com.au/analogmagik-tutorial-3-how-to-set-azimuth-on-your-cartridge |
@trinitrond BTW, think you should start a new thread on this amp, it probably will deserve it. Some like "Mytek Empire power amps, with GaN based technology." Cheers George |
Hmm! interesting, could be a winner. They talk about transistor switching (hopefully frequency used) and "very gentle negative feedback" resulting in "silky tops". But don't give any details of the switching speed, feedback db's or what phase shifts are in the upper audio band "tops" The thing I don't like to see is it only has 10kohm input impedance, not good for preamps with small value capacitor coupling, passives or most tube preamps, yet they give the choice of two gain setting 23db or 29db latter being good for passives or unity gain preamps. Time will tell when one is bench tested. Cheers George |

Technics SU-R1000 GaN technology integrated getting closer. Looks like it’s on the way in limited numbers, as they ask for payment in Japan and it's made to order at the moment, around $8.5k. https://www.audiounion.jp/ct/detail/new/177765/ Haven’t found if it use the ground breaking 1.5mhz switching frequency that Technics use in the flagship SE-R1, but they do say on other sites it uses "very high" switching frequency?? What I did find though for the "vinyl crew" which could interest or disgust them, is it looks like you get a calibration record with this amp, to play your phono cartridge with and the SU-R1000 analyses these tones and then digitally equalizes it dead flat. (should sound just like cd then, but the channel separation will still only be 30db at best can’t fix that) Cheers George |
Here is Technics 45min!!🥴 propaganda video for the SU-R1000 integrated. Actually it's only 24mins, the rest is for a new server or something. Wait till you see the size of this thing on the table in front of the three boobies at 6.45 into this. It's a lot bigger than I thought it would be, no wonder it's 22kg https://www.youtube.com/watch?v=b-BJifbtjbI Cheers George |
Here is one in black. https://ibb.co/xhsfm4b You know it has an 8mm!!! thick front panel and 6mm sides and top! "it’s a swiss army tank" Also while not a review yet, a good deal of spiel on it here. https://www.hifi.blog/technics-su-r1000-integrated-amplifier-the-first-integrated-amplifier-of-the-r... And this is interesting for the T/T crew, all phono stages I know do their RIAA curve using passive componet filtering this thing does it using digital filtering, said to mimic much more accurately to the RIAA curve. and be less noisy, less distortion as well. Cheers George |
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.. SU-R1000
"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 https://jp.technics.com/products/r1000/images/ph.jpg 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 AmplifiersCheers George |
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."https://soulution-audio.com/series7/soulution-701-mono-amplifier/ Cheers George |
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. Cheers George |
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 Cheees George |
I know why now why there’s no reviews mentioned yet: "Scheduled to be released in mid-February 2021" Found some pics on a Japanese website, very impressive internals for a Class-D. And the outside looks good also. https://ibb.co/gPP3cwr https://ibb.co/Ldr5kWF https://ibb.co/VMf13gw https://ibb.co/WPpxynF https://ibb.co/RvrdbcC https://ibb.co/jRnN4jR https://ibb.co/gw2JwPL Cheers George |
