Do I need to add more components to make this transformer safer?

Dear all Electrical and Electronic Engineers,

I own an audiophile grade Sony blue disc player.  It accept 115V AC.

Then, I bought this transformer which transforms my wall outlet 230V AC to 115V AC, which is then connected to my Sony Disc Player.

https://hk.element14.com/triad-magnetics/vpt230-110/transformer-toroidal-2-x-115v/dp/1785731

Do you think whether I need to add additional components to make this transformer safer to work?  I have already bought another beautiful aluminium enclosure to contain it.  Grinning

The main point is - it is an audiophile grade system.  Additional components may degrade the final sound quality.

So, there is a dilemma.

    The only way you will hear any difference is (perhaps) if you drop them both on the floor. The transformer you have chosen should be fine if it's power rating is sufficient (25VA sounds very low for…

    No dilemma at all. IMHO, if you have an audiophile player, it has no audio power amplifier. As long as your power supply can supply the power peaks of the dynamic range, its OK. That being said, 25 VA…

    ..."Der Transformator-Spezifikation sagt 220 mA FLA. Ich weiß nicht, wie dein Leistungsbedarf für die Spieler ist, aber nur zum Spaß tu so, als wären die 25 VA Unity PF, also Watt. Der Transformator ist also vielleicht in Ordnung. Ich habe einen günstigen Blue-Ray-Player mit HDMI-Ausgang, der 10W und 12V bei 800 mA verbraucht."

    Please don't merge two values: 10W / 12V/800mA DC is not the same as 115V/220mA AC.

    Relatively, in his calculation with your player - in his player (i don't know??) is built-in a power supply, as well as a controller with buttons, a display, etc.. which need also a bit of "water".
