pa phase out na ba 1400?
Matagal na bro. 1500 was last year's model and meron nang 1600. But since yamaha always trickles down their older technology to newer lower models. Its safe to assume that the 1400 has its technology trickled down to the Yamaha 750, except for the amp. They use a different amp for the x50 and the x500 (or x400) series.
And the 1400 is THX certified, and one of the THX licensing criteria is "'The power amplifiers should be unconditionally stable, have a power output in excess of 100W per channel into 8 ohms, have low distortion and wide dynamic range". The quote is from Lucasfilm's Home THX Design And Licensing Manual.
I dont know where I read this, but the lower series' posted power ratings are stereo (2 channel) and they divide it to 5,6 or 7 channels when you use multi channel. Thats why the lower series true power ratings in multichannel reach only about 30+w when I saw it in a review.
I think this is also the reason why I have read or heard some have commented that Yamaha sounds thin or underpowered. This is due to the fact that they were referring to the lower series of Yamaha (w/c is commonly used by more people) and not the higher 1x00 and the 2x00 series. I, for one , am guilty of this, having used a 450 and 650 before.
just my 2 cents
*lower series refers to RXV350/7, 450/7, 550/7, 650/7, 750.
