If you are really concerned, then disconnect your amps from the transformer output and let it run for an hour or so and measure the temperature rise. Some cheaper transformers have higher magnetising current due to cheaper and lower grade core materials used that could make them a little warmer than expected. If the transformer does not get sufficiently hot with no load then you may find that the transformer designed regulation is not up to scratch. There may also be some nicks in the lamination causing higher Eddie currents and hence rise in temperature. I would not like a transformer running at 80 degrees centigrade for extended periods, you could get burned.
Hey! Sometimes toroidal transformers get hot from induction heating the mounting screw. The reason is high current flowing continuously. You should check if the screw on the tranformer is warmer that transformer itself. I had some issues like this so i decided to attach transformer with a plate of aluminium and 4 holes outside transformer core.

A toroid can only be secured by a centre bolt and plate else you have a potential fire. Everyone should know this.
That is absolutely not true! There are also fully encapsulated toroidal transformers with mounting holes outside of the transformer as well as epoxy laminated center nut/thread, upright standing mounts etc.
Why not just epoxy it to the mounting plate, use four cable ties, use plastic mounting materials, cement it into a box. let it lie on the floor.... You show a core, what for, mounting it? You show a screening box, if you do not pot the box the transformer will rattle inside. Would love one of those brown things in an upmarket amplifier. Sell that idea to Parrasound or Linn, or MacIntosh, it would really boost their products appearance.

I don't think that 6mm nylon bolt can handle 400VA tranformer. In my case it was 1000VA transformer and i decide to use harder materials.
What has made a big impression on me besides the detail and the 3D stage it is the full extended bass.....
Can't judge how it sounds, yet it looks like a work of art. Well done.
Huh..is this a cell phone recording? This Krall song sounds unusually vivid and bright than I've heard in different systems before. Then again, I like vivid.
Yep. a simple old mobile phone xiaomi redmi note 5....
And I haven't bothered at all with the program Foobar Dsp etc....
Preamp Salas DCG3 and Mirand dac 4490 from Sonny at 88khz sample or 96khz songs.

Yes, I hear the detail and the 3D stage, Nikos - but I'm glad that the AN also delivers extended bass! 👍
In my 3-way active system ... I can't judge the AN's bass - as my 'mains' hand over to subs @ 110Hz. 😵 (My two ANs drive my mains.)
