3e Audio A7 [TPA3255 PFFB Stereo] Finished Amplifier - User Impressions | Owner's Thread

[pieterv1]

we may only focus on pure amp this year and combo amp next year if every going well.

With "pure amp" do you mean a poweramp (no volume control) with integrated PSU? And 12v trigger please

If so, it'll probably be my next purchase.

Hi, 3eaudio

I just ordered the A7 from AliExpress (with a separate GaN PS), and checked with Rel about connecting their high-level capable subwoofers high-level. They say it's ok, so long as the black wire is connected to a rear chassis screw.

I understand the A7 is dual-mono design? WIll this cause any problems with my Rel (S/812), do you think?

Thanks

i am not able to find the senstivity of high level input but as it can accept that should work, just not sure whether has the correct gain for your case.

I'm using REL SW as well. red and yellow wires connected to positive speaker-out terminals, black not connected in my case since I don't have any type of ground loop

The A7 stereo is a dual mono design (except for shared power supply)

This is a good point... I'm remembering all the debate about the Fosi V3 Monos coming with a single power supply option, with many saying really two power supplies were better. And then the A5 seems to have better channel separation than the A7 stereo for some reason. I went for the A5 - sounds just as powerful - probably more dynamic even than the V3 Monos, but without the enormous power supply (or supplies).

I would expect the two modules (dual mono) being in the same housing will use the clock sync functionality. In which case the problems fosi had with the V3 mono won't apply.

Just received my A7 & unfortunately the right channel is not working correctly. Return initiated. It arrived fast, hoping the return & replacment is as fast.

@3eaudio I’ve recently upgraded to the Wiim Ultra streamer and am now encountering an issue where my A5 amplifier, from the original batch, automatically turns off at low volume levels. I’ve tried disabling volume bypass and setting the volume to 95%, but that hasn’t resolved the problem. My subwoofer, connected from the Wiim to the SVS, remains active at low volumes, yet the A5 continues to shut off. Could you please help me find a solution for my A5 amplifier from the first batch, where this issue was addressed in subsequent batches?
