I have seen one used on the web indicating 170 watts per channel. Everything from Marantz says its 150 watts per channel. Is this a case of someone "pumping" up the wattage or are there different models out there??

Also, assuming its 150 watts, would that be a noticeble difference from say 125 watts or do you need to get up to 200 watts plus to notice a difference from 125 watts a channel?

Thanks.

It's 150 at 8 Ohms.

Technically speaking, you would need 250w to get a significant increase in SPL with nothing else changing, but the reality is it depends on how "real" the 125w you have now is. A separate amp will typically outperform most receivers, since the amp is built to do just one thing.

I have a Marantz 8300 rated at 120wpc, and I use MA500 monoblocks rated at 125w. While the sound is basically unchanged, there was a noticable increase in detail and depth when I added the amps, as well as the fact that I can crank it louder without compression. At normal listening levels, it sounds about the same, but at elevated levels the difference is obvious.

Thanks John, thats what I have been trying to decide if a 125w to 150w seperate amp would prove to be a benefit or not for HT usage.

Also trying to find a 200W 3 channel but not many out there.
