Apollon 1ET6525SA ST Purifi-based class D amplifier an Q Acoustics 3050i?

[josef119]

Hello everyone,

I was very impressed by the test of the Apollon 1ET6525SA ST Purifi-based class D amplifier (https://www.audiosciencereview.com/forum/index.php?threads/apollon-1et6525sa-st-amplifier-review. 68779/) – not only by the measurement results (thank you very much for those!), but also by the apparent solidity of the construction. In the future, I would like to replace my Wiim Amp Pro (which I really like) with a higher-quality amplifier. Does it make sense to use such a powerful amplifier as the Apollon in a room measuring around 30 square metres with Q Acoustics 3050i speakers? Or would it be completely oversized for the speakers, for which the manufacturer recommends 25–100 watts? Could the amplifier even damage the speakers? And finally, the question of how to find the right gain settings, which I have not yet been able to set on any of my devices.

Many thanks in advance for your answers to a hi-fi fan who is not particularly tech-savvy, and best regards!

Josef

Keep your money and the WiiM. There really isn’t much that the Purifi can add unless the WiiM doesn’t play loud enough.

My best advice is:
Buy a cheap multimeter, measure your WiiM's output voltage with volume adjusted to your preference, and that's all you need to compute how much output power and gain your new Amp would need to have.

That being said, you'd be significantly better off investing in a new pair of floorstanders, a subwoofer or two, a measurement microphone, or some room treatment instead.

If you want a new Amp hoping it will improve something, without knowing what that is or having solid grounds that it'll do what you want it to, then you're most likely wasting your money and the new Amp will sound exactly the same as the old one (excluding expectation bias).

Could the amplifier even damage the speakers?

If you keep playing and pushing even if the speaker is already crying out for mercy so to say, then yes.

It is hard to damage your speaker because your ears will hurt before that. The likely scenario is that you for some reason leave the volume at max, start playing some song then turn on your amp. But even then I would be worry about your ears more than the drivers.

Upgrade the amp because you 1. Have a bad amp that is high distortion and/or clearly underpowered (not this case), 2. Have the money to spend and you already optimized other things. I don't need a new amp but I usually think about buying a purifi because, well, it is nice.

Things you can try.
- room correction
- room treatment
- add a sub, or two
- speaker placement (move left, right, away from wall, toe in, toe out)

Agreed with the above, and probably the speakers themselves would be better upgrade than the amp driving them.
