- Thread Starter
- #702
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
I can compare 3E Audio A7 monos with my NC400, NCx500 and Nilai500 and still prefer 3E. Of course only subjective opinion

@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.
I simply mean, if it can switch input based on signal input i.e., RCA vs XLR then many would appreciate the convenience.

I can't decide between a5 or a7... My floor-mounted speaker system is 4 ohms 89 Db

Both amps can handle loads down to 2 ohms.
Without knowing e.g. your room since, listening distance, desired average volume it's hard to tell if the A5 will be sufficient. It well might.
Remember that 250 W vs 150 W only buys you 2.2 dB of SPL headroom. That might be anything from irrelevant to exactly what you need.
Where this coupon works, on ali below?
When buying on Ali you send amp with SOYYIN, not 3e Audio brand?

They never had any branding on front face in previous batch.
indeed, I didn't pay attention to it before, here is no brand at all:
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.

@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
will setup some discussion in ASR soon.

Is the promo code no longer valid? I wanted to order, but now the price is not very encouraging.
even at "full" price these amps are more then a bargain...
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?

You can buy A7 Mono and Stereo with 48V 5A or without PSU, and 48V 10A PSU should available on another offer. (was yesterday)

correct! @dilu FYI...
- the reason we don't include 48V/10A is due to the whole package weight is too high which will increase the ship cost significantly.
- if run with 6/8ohm speaker i would recommand go with 48A/5A is enough for cost effetive.
- if run with 4ohm or even lower to 2ohm, then it make sense upgrade to higher current one 48V/10A
- A7,A7Mono and 48V/10A PSU now they can be ordered separately
so as is will run 4 Ohm speakers with it the 48V 10A power supply would be recommended. (Arendal 1723s Tower & Center - LCR)
But you dont sell the 48V 10A on your own right?
I checked the price when i buy the 48V 10A Aiyima power supply seperate, but then Audiophonics is cheaper the buying directly from you via Ali. They state to deliver with the 48V 10A power supply.
Do you have an information from which time on they will have the updated version? (the change in standby conditions is necessary for me)
