WiiM Amp Ultra Experience

No! No respectable amplifier designer would release an unstable product sans load.

Is it Naim amps that aren't happy unless you use a particular speaker cable?

In reference solid state designs they ought to be but I simply tell you that it is not so black and white as you think it is. But I already gave up and will shut up now. Have it your way, everyone is free to do as the please off course.

I would like to know as early as possible if the amp is not designed to be powered on without speakers (although it shouldn't be a problem)... An initial setup is a good moment in time.

Moving on…

I measured the temperature of the Amp Ultra and saw about 110F (43C) in a 80F (27C) ambient temperature. Pretty normal.

If you want a shouting match or power struggle (looks like it, I can be wrong) I'm not your guy. Sorry.

Do not know. Maybe @Burnside can comment. I think he has experience with those.

No struggle. Just replied to your post. And now I am done.

Yes, you're right with Naim.

My copy did not complain.

Yes, you're right with Naim.

There is your (just one) example.

Well, I can distinguish WiiM and Naim.
And I'm not sure if that's a valid example of the solid state amp which must have speakers connected.

Can we go back on topic please?

Yes that would be good.

As far as I remember Main used to ask for either their own NACA speaker cable or alternatively a 4 mm² cable twisted twice or so per meter. They also asked users to use equal cables of at least 3.5 m or something like that.

Absolutely no damage would occur with typicalal standard speaker cable. The amps were said to possibly not be stable into very high capacity boutique cables. I should have an old manual lying around.

Looks like this thread might need some clean-up.

Another thread. Another argument.
