I bought a Rotel RA-630 that looks just like the RA-12 but only has 1 set of speaker outputs it says it is 60 watts just pluged it in to replace my Rotel RA971 also 60 watts. Turning up the volume the new amp is only half as powerful why?

Hi. I'm affraid ID is right, and that is a fake. The only report I could find of a 630 led me to a .co.nz store. Googling it further, brought up an article of said store having to retreat fake PlayStation 3 from their store. However, clicking the article made Google say the page was not available, despite the page clearly loading for half a second before the message. Weird stuff. But try to take the amp back. You're way better off getting a used RA1520 or Arcam A19 for that money.ID. said:ciaranb said:I bought a Rotel RA-630 that looks just like the RA-12 but only has 1 set of speaker outputs it says it is 60 watts just pluged it in to replace my Rotel RA971 also 60 watts.

Because it's a fake? Can't find anything online about a Rotel RA-630.
Otherwise the most likely answer is, that it isn't less powerful. Just how far you have to turn the volume pot to reach the same power output differs. Perhaps the RA971 reached max volume very early on (like 10, 11, or 12 on the dial) while the RA-630 lets you adjust the volume more finely and doesn't hit max power output until your turn it further around.
Here, let me Google that for you
"I just spoke to the shop I purchased from who've said the volume control is an exponential type, which would be a good thing as it gives more control at lower volumes."

ciaranb said:Just had a listen to the Arcam FMJ A19 today and it had a linear volume increase much easier to use I think.
ciaranb said:With the A19 I am about 45 and the RA12 about 60 to reach the same volume though this is rough as they are in different shops,speakers...
ciaranb said:If I run it up to 80-90 on the RA12 listening to rock music is this OK or should I be looking at a bigger amp? At what level does the RA12 produce unwanted distortion?
