After the HR review in Stereopile, I'm surprised that the LKV Veros hasn't attracted more attention. No measly switching power supplies there--one main toroidal and two subsidiaries. No wonder it's so heavy (and costly)!
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
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 |
I own an A/B 105lb. amp. I love it, but I don’t have zip against class D newer technology. There are just too many good reviews now saying the sound quality is superb with the tone, color weight, and dynamics, and over-the-top musical. Class D is not the class D from 10 years or so ago, this is like saying Vinyl stills sound like they did in the 1930s, turntables still looked the same, CD still sounds like it did in the early ’80s, no everything new technology improves and digital bashing is no longer justified. As I age my next amp will be Class D, I no longer want to pick up a 105lb amp at some point. Time marches on and new technologies continue to move forward, soon most cars will be battery-powered, can sit and look back but that will not stop where audio is going, and those making Class a or Class A/B amp will soon be making class D amps that sound good, Jeff Rowland for one saw the benefits many years ago. Now Technics, Mola Mola, are making 1st class, class D amps that may take our systems up to a level we never imaged possible. These products are not cheap either and well made. |

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 |
