I just buy it at last month, the sound really good. If l want my dream sound with this setting , maybe l need to change new speakers. I am sure will be a another new level.
I own a ShengYa S10 CDP and ShengYa SA-T3 Pre Amp into ShengYa SP-T300 and SP-333 amps driving Aurum Cantus Music Goddess loudspeakers, beautiful sound.
Sorry, thank you for your good feedback, and now we have the latest version A-75 class A amplifier: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DpNG07FsfEs.htmlsi=ARN0VUsUiO5xlImt
When I lived in Beijing back in the 1990's I bought a big mosfet power amp with a tube preamp. It was made by Kones. I believe they are defunct now. Have you heard of them? The amp and preamp was pretty good but their speakers were so so.
Oh, you come Beijing so long ago, Yes, you are right, the Kones brand is disappeared, I have never heard them too, but therer is some excellent amplifiers brand in China, it is very good indeed, because of the moreden testing instrument have made great progress, it can help us to do the audio products better.

@@alanrogs3990 Oh, we will build sales network in US and Canada for our tube amplifiers, and I know Opera brand don't like to sale on line, so we didn't contact them.
This looks like a quality amp, I wonder if it has a 12v trigger port... as well as how much does it cost & how much is shipping? I would be interested in this product, what is the warranty like & who takes care of the warranty claims in the USA? Nice video, thanks!
Hi, thank you for follow our production, we can make a 12V trigger port for you, recently we only sale it by single one to wordwide, of course, this is a testing /experiential sale on cheap price, because we feel it is very good. Now international shipping from China is very quick and easy, so we can send all repair parts to buyer as a warranty, not 1-2 years, but 5-10 years. of course, the buyers must tell me what parts they want, so those buyers must know where the amplifier problem come from when they need service aftersale. this is the sales link: 000080huang.en.alibaba.com/product/1600268066025-820373597/N_051_Class_A_power_amplifier_fully_balanced_low_noise_study_clone_Auccphase_A_70_RMS_100W_2_8ohms_200W_4ohm_400W_2ohm_800W_1ohm.html?spm=a2700.shop_plgr.41413.8.1e785d933gphnE

Nothing wrong with the sound, but I think you should use another kind of music to showcase this beautiful amplifier. You could use free stock music; something that most people can identify with. In any case, you are aiming at a market that don't understand the inflections of Chinese language. Is that mandarin?
@@quanyhuang3178 sorry you mean the amp? I am looking more for a line preamp clone I see many on aliexpress but i know nothing about their sound I have already a decent power amp and i need very few Watts
Sad but evident. This is a fake video. Sound meters do something else while an original recording is embedding. This no sound reproduction via the Amp in the video.
