One of the most interesting parts (once we definitely settled in linear campus) was about transformers. And here are the most important points.
1.
EI transformers sounded better than toroidals, for their better dynamics, more quiet background, and more natural tone.
2.
Lower power transformers sounded better than higher power ones. This finding was totally opposite to what audiophile common sense would predict or recommend by usual over-sizing recipe – higher power units were more thin and bright, whereas lower power units were more smooth and dynamic.
3.
EI transformers positioning was critical, as one might expect, due to their higher external electromagnetic dissipation; interestingly, with Gramofone units we used external supply units, physically well separated from active electronics, so supply couldn’t upset it, but this issue with positioning also appeared when we dealt with mutual positioning of two transformers (we had one isolation unit, and another one main unit). We found this setup did sound better when two transformers were placed at 90° one with respect to the other.

In practical terms, since there are things that generally apply, one may draw her/his own conclusion based on particular requirements or possibilities. Transformers do have their power capabilities, so it is not recommended to go below their power specifications.
You should also consider that transformers can not really work right at their specified power rating with usual supply rectifiers, as they must fill capacitors by 100 Hz (or 120 Hz) spikes, so these spikes must be higher current pulses than if current flew constantly. But once you fulfill this power rating criteria, it is good to start thinking “less is more”, and stay at that power and not to go above, because this way you only increase transformer’s bandwidth, and increase its external electromagnetic field. In other words: yes, there is a right power for every transformer used in the audio.
So, as said, some of these things probably counteract to what you have learnt about mains transformers sonic properties. But, as one fellow audio enthusiast wrote in the early days of the internet (when internet was young and pure), “most things we could learn about hi-fi were simply wrong anyway”.
Sad, ovo se odnosilo na drugi tip uredjaja...ali u spisku dijelova Pedja je specificirao transformator od 50VA
uglavnom nebi se opterecivao s tim
mozemo pitati Pedju za preporuku...
ali mislim da je ovih 50VA primjereno
by the way...meni EI ne odgovara radi velicine i problema sa smjestajem...tako da ja moram ici na toroide...
