Technics SU-R1000 a new Class-D GaN Technology integrated
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 |
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 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 |
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."https://soulution-audio.com/series7/soulution-701-mono-amplifier/ Cheers George |
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.. 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 |

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 |
@georgehifi, "Here’s something interesting, they gone all out could be a good sign" ... the 'Battery Driven Clock Generator' reference on the site is used in all three Class Divisions (Premium, Grand, and Reference) and is not new nor only found at the Reference Level Class of products. From Technics Site: "Technics has extensive experience in circuits using battery isolation, having used them to create ultra-low-noise pre-amplifier stages in past analogue amplifiers." Jitter Reduction (as a theme) is also found throughout the full range of models. " JENO Engine (Jitter Elimination and Noise-shaping Optimization) " The SU-R1000 features newly introduced Tech Innovation apart from previous models in ' ADCT (Active Distortion Cancelling Technology) ', 'Advanced Speed Silent Power Supply', and 'Intelligent Phono EQ' consisting of: 1) 'Accurate EQ Curve' 2) 'Crosstalk Canceller' 3) 'Phono Response Optimizer https://www.technics.com/us/products/reference-class/integrated-amplifier-su-r1000.html#specs |
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 |

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 |
Two part review up below, thank Google for translating this. Seems promising. https://av.watch.impress.co.jp/docs/topic/special/1298192.html https://av.watch.impress.co.jp/docs/topic/special/1300097.html |
trinitrond1 posts02-28-2021 6:57am Two part review up below, thank Google for translating this. Good catch, that second part is even more informative, could be a realgood unit especially for the vinyl brigadeCheers George |
Another review that tells us very little. He liked it, that is for sure. However, he did not compare the $10K Technics to his $26K Pass mono amps or any other amp or integrated amp. So, what do we know?: It sounds better via digital in than analog in using a Manhattan II that uses an ESS dac chip and ordinary op amps. Whoopie! I could have told you that it would sound better than a decent DAC and interconnect via analog before even listening. However, how does the analog input sound driven by a serious DAC.....say the MSB select or the big DCS Vivaldi? How does the analog input compare with a Pass or other $10K+ amp? We will have to wait and see. For sure, there is a lot of cool technology here in this digital integrated amp. The LAPC feature cannot be done without it being a digital integrated amp. The future looks good. This really cannot be compared to a normal class D amp as there is so much more going on here. We will have to wait for someone else to more fully review this product. Some serious A/Bs are necessary. |

I would also like to learn more about this integrated, hoping for more reviews, particularly with comparisons to other equipment. A lot makes sense regarding the technology, and for someone like me that streams only for audio, and wants a HT bypass this is another nice option. Looks great also. I am hoping Music Direct gets a few in as they list it. Assuming their return policy would be good with this I would like to try it (with the intent of keeping it if I loved it). I've always liked Class D for bass, but I do like a big soundstage and do not want a treble forward unit. |

https://www.whatsbestforum.com/threads/a-new-wave-of-class-d-integrated-amplifiers.31281/page-4 "....It sounds very clean, clear and smooth like nice breeze in summer mountain with high resolution. However mid and bass are thin and light. I recalled the sound of Magnepan. Digital input from fidata sounds better than analog input, as its resolution and tonality. In my view it is the best except phono input I didn't listen this time." |
More GAN incoming, now from Mytek. https://mytek.audio/shop/empire-monoblocks-2#attr=11 https://www.hifi.blog/mytek-empire-monoblock-immense-power/ |
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 |
@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 |
Will do! I have owned a Manhattan II and really appreciate what Mytek is doing for audio in general. We will probably see more and more GaN based amplifiers in the coming months and years. Below article from Infineon gives a interesting perspective on the switching characteristics of GaN, though their switching speed seem to be lower than Technics. https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.infineon.com/dgdl/Infin... It really struck my how far ahead of the curve Panasonic/Technics where with their r&d, you can appreciate what they do for vinyl, but their amps should be wider recognized. SU-G30 and SE-R1 is now 5-6 years old but still relevant. I currently work in the IT industry for a TW company but worked in partnership with Sony for 10+ years, appreciate their history and innovations(the ability to commercialise ideas out of Universities), browsing thevintageknob you realize how the audio innovations of Sony, Panasonic etc is not that widely recognised in hifi circles. (One of my best experiences with Sony in audio was to try at home the TA-N1/TA-E1/SCD-1 combos with my difficult to drive Martin Logan Ascents, magical music experience, leads you to listen to albums instead of just testing different tracks) Maybe because they create too many budget solutions with their logo on, that their PR department focus is less on the high end products so the devices is not seeded to KOL, leading to less reviews and less recognition outside Japan or maybe due to less partnership with hifi retailers in the west. I just bought a SU-G30 and the sound is really fluid, with a glass like high end which is really 3 dimensional, with a powerful class-d bass performance. It's " only" 50w but my speakers are rated at 87db/1w and I feel 95db+ is a bit to loud at home anyway.. Though the streaming app feature leaves a lot to be desired (also a culprit of Japanese companies to treat the software as a afterthought) but it works really well with Audirvana over DLNA with DSD 128, Flac 192 and Tidal. Support innovations where it's at, if it is a boutique creator or a corporate giant, r&d budgets and marketing budgets is often function of your sales revenue. |
Here more info on this new Technics Integrated amp and they are also coming out with a new "all in one system" called the Ottava F SC-C70MK2 that has much of the technology found in their top of the line high priced Reference R1 Series too ! https://www.youtube.com/watch?v=b-BJifbtjbI&t |
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 |
https://www.av.de/print/audio-test/audio-test-3-2021-die-neuen-verstaerker/ SU-R1000 receives 9/10(Referenzklass 98%) sehr gut from Audio Test. Der R1000 ist ein Diamant unter den Verstkärken. |
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 |
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 |
Hi George, I searched and can't find that source, it was a late night. But I did just receive more pre-arrival information from Technics. Now this is on the Jeno engine Low Jitter section so not sure if it what you are looking for, my rep says he will contact the factory for me if not. From Technics... JENO stands for Jitter Elimination and Noise Shaping Optimization Digital signals of various music sources come in with various sampling frequencies such as 36KHz/44.1KHz/48KHz/96KHz/192KHz. Therefore, before processing, these signals have to be upsampled to a sampling frequency that is the least common multiple of the input/output sampling frequency, and then decimated at the output sampling rate again. Since this oversampling signal processing accuracy determines the performance and sound quality of the entire amplifier, it is necessary to ensure maximum accuracy. The digital audio signal input signal is first input to the “Low Jitter Sample Rate Converter”, and the sampling frequency of the sound source input at various sampling frequencies is converted to a single PWM drive frequency (768KHz). In order to perform PWM drive with high accuracy, the signal must have no time fluctuation. Therefore, a PWM signal is generated from a highly accurate clock signal obtained by the crystal oscillator. On the other hand, the input signal contains jitter due to the influence of the transfer path, etc., and is asynchronous with the output. In order to synchronize the input signal clock with the internal processing clock of the amplifier, a highly precise Sample Rate Converter is required to have the function of converting the sampling frequency(“over”-sampling) while removing the input jitter.

"The Technics SU-R1000 is one of the most unique we have seen and heard in the High-End CLASS" !.. https://www.lbtechreviews.com/test/hi-fi/technics-su-r1000 |
The Technics SU-R1000 is Reviewer Francisco's new Reference Amp, and all other amps will be judged by now ! https://www.youtube.com/watch?v=1w-ADkMSwfM&t |
the lbtech review does not even compare the amp to anything except to say it is not as powerful as the Mac or Hegel.....so what does that tell?....nothing. The Spanish review says what? Most of use don't understand spanish and there seems to be some pointing to a page that shows? a Mac and Pass labs integrated rated? better? He has his JBL speakers (that don't don't image that great stock) right up against the wall......what kind of soundstage can he get? Not very good. These are not serious reviews. We need a serious review by a seriously tweaky high end person....that actually describes the EXACT differences between this amp and other amps in its price range (both integrated or not) and the all out state of the art amps.....then we will maybe....know something. |
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 |
I am not sour or bitter. Just calling it as I read it. What do you gleem from the reviews so far? I WANT this thing to beat everything. This is why I am not pleased with ALL the reviews, so far. What I read is that it is a great $10K integrated amp......but not a world beater in any way. I hope more and better reviews can shed some light. It is very clear that it is a very good integrated amp. However, the technology is so far out there that I had hoped that this amp would beat everything. I bet the AGD Audion’s are much better....then we have the $6K Mytek GaN amp coming in a few months, modded Purifi, modded IceEdge, $3K Wally GaN amp (the "waiting for Godot" amp), etc.............time will tell. The LKS 005 DAC is superb......that DAC driving a pair of AGD Audion’s is the same price as the Technics......if the LKS/AGD combo is better....well....the Technics would be history. Of course, some people will prefer a single box and if you have a modest turntable system, then the phono in the Technics looks interesting. |
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 |
