Yamaha RX-V440 v.s RX-V450

I bought an RX-V450. Ita has much more massiv transformator and power rating is bigger too. But now I saw in tests, that RX-v440 tested power in stereo mode is ~100W, but RX-V450 got only 60W
In RX-V450 test there is no information, that is it tested in stereo mode or 5.1 mode

The question is, that is 440 better than 450(power outpu I mean)?

Ja ploho govarju po russki.

B teste RX-v440 polušil 100W, a 450 polušil 60W
450 bõvaet bolšoi transformator.(sravnits 440)

Information in some tests or on some sites often can be wrong. By all means, if I were You, I wouldn't worry about. If only You would't use it the church or stadium .

Ok, You made me feel much better.
