why onkyo 605 US 90w and onkyo 605 EU is 140W

[blackend]

why the EU versoin is 140w while the us is 90w?

I think it has to do with the way the power transformer is connected to the mains. US version uses only half (120V) of the primary winding, while the EU version uses the full primary winding (240V). Just a guess.

That would be my guess as well...... Wish they had 240V here , its cheaper to use !

Just to let you know, all else being equal, 140/90 watts is 1.92 dBs more volume sound difference.

Just like this site someone interjectiing facts into the discussion.

There could be several explanations, but the bottom line is probably that both have the same power, and suggests that people really shouldn't be worried about small differences.

There are many different ways to measure power, especially with multi-channel amplifiers. These are the typical differences:

Number of channels driven - one, two, five, seven?
Criterion for max power - clipping, 0.01% distortion, 1% distortion?
Speaker load used - 4 ohms, 6 ohms, 8 ohms?
Continuous or instantaneous power?
Safety certification constraints related to overheating?
Claimed or measured power?

Each one of these factors can account for the variation mentioned, and there's not way to make a fair comparison unless all those variables are levelled.

Probably because our dollar is worth so little at this point they have to use smaller amps to make a profit

90w is good for a room that is _?_' by_?_' it seems to work in my wife & eye's bed room & its huge its at least 2 & half times the size of an average master bed room
