- auto-off disabled is under review by FW engineer.
I can compare 3E Audio A7 monos with my NC400, NCx500 and Nilai500 and still prefer 3E. Of course only subjective opinionNow I'm wondering, whether to take 3E AUDIO A7 or Audiophonics Hypex NC252MP...
What do you guys think?
@3eaudio I would add something on auto-sense here. Currently it only powers ON/standby the amplifier but another great option would be to add input switching as well.we had made some change base on user feedback and suggestion from ASR member, thanks again for all of your advice and help us keep improve.

- Auto power off time set to 20 mins
- Increase audio detection sensitivity RCA: 200uVrms; XLR: 400uVrms,this significantly meet some user listening in very very low volume.
- Auto audio sensing power on/off can be disable/enable by user,appreciate @Bushellj
Both amps can handle loads down to 2 ohms.I can't decide between a5 or a7... My floor-mounted speaker system is 4 ohms 89 Db

They never had any branding on front face in previous batch.When buying on Ali you send amp with SOYYIN, not 3e Audio brand?

3E AUDIO A7 Amplifier
3E Audio, a recognized player in the DIY world, now offers a Class D Stereo amplifier incorporating audiophile Hi-Fi components. The A7 amplifier is based on two TI TPA3255 chips in PBTL configuration, and two dual OPA1612A OPAs.www.audiophonics.fr
@3eaudio So this batch won't have any branding too, or have Soyyin?
yes, in progress and prototype build will be in June, launch plan is end of 2025.@3eaudio slightly off-topic... Are you still planning to launch new versions with integrated PSU? I remember that this was in the road map if the current generation of amps was a commercial success and, from what I can read here and there, it seems to be the case![]()
Is the promo code no longer valid? I wanted to order, but now the price is not very encouraging.btw, they are available again and would like to share coupon to ASR member : ASRDIS15
even at "full" price these amps are more then a bargain...Is the promo code no longer valid? I wanted to order, but now the price is not very encouraging.
You can buy A7 Mono and Stereo with 48V 5A or without PSU, and 48V 10A PSU should available on another offer. (was yesterday)the A7 mono is just available with a 48V 5A power supply or without a power supply.
As in see in earlier posts you sold it with a 48V 10A power supply. Why dont you sell it with the bigger power supply anymore?
Is the 48V 5A enough to get the full potential out of the amp?
correct! @dilu FYI...You can buy A7 Mono and Stereo with 48V 5A or without PSU, and 48V 10A PSU should available on another offer. (was yesterday)
48V/10A PSU is no longer available on
