elctrocompaniet eci 80d quality and reliability

[janul]

Dear audio enthusiast,

I recently purchased electrocompaniet eci 80d liking its sound. I did chcek some reviews before and after and I have to say I do have doubts about its built quality and possible concequencies in its acuracy in sound performance. Namely if you chcek pictures from whats going on under the hood, you can see thet there are two small inductores. Both of the output cables are conected way to close to them. I am not amplifier specialist by any mean but in elementary school we studied that the inductor does produce magnetic field. The output terminal cables are suncked in this magnetic field and I would like to know what negative efects does this have on amplifier performance. I have to say that I realy do not understand what I see under the hood of some british as well as electrocompaniet (being norvegian) compared to japenees amplifiers tideness.

Thank you for any clarification and help
Jan

Looks like power supply is the right board. The main left board has the digital conversion and headphone amp circuitry on the bottom, the output transistors attached to the heatsink on the top, and of course the long speaker wires crossing the amp to the bottom right binding posts.

What I'm not sure is why there are these center inductors and looks like rectifiers in the middle. First I thought of a class D output filter, but it's class AB, so no need. So I still have no idea what they do.

But I agree that the wire routing is not optimal. Even less with untwisted, unshielded wires, which AFAIK are more exposed to EM noise.

I have update to the topic. After some not very extensive accoustic treatment of the room, by my ears the amplifier does perform really well. I have also chceked layouts of some more expensive amplifiers and by my humble but honest conclusion (whatching parts placements, cabling, some percieved tideness etc) the amp is not backward in its build at all, maybee even over avarage.
