125 watt or 80 watt?


I am looking to purchase a carver amp. I want either the 505 or 705 that has 80 watt and 125 watt with thx rating. I currently have a marantz sr7400 that is up for sale here. Will i be able to tell a differnce with the 80 watt? i am in a bedroom that is medium sized, will the 125 be overkill? How good is the carver amps? I can get the 705 for 350$, would i be happier with 705 or 505? i know there are alot of questions but i need to know if this is worth it. Thank you for the time

Remember i am trying to keep this whole "upgrade" below a reasonable price. 350-400 is about all i can spend on an amp, and i would like it to be a 3-5 channel one at that. I am into the home theatre aspect of this and music dts dvds also. Please, any input that anyone has is awesome.
You would be better off with a good used Onkyo 805:

I don't think wattage differences here should be an issue either way. Other factorss seem much more important. Like features.
Dlcockrum,
You think i would be better off not even getting an amp/pre amp set up? I can get the pioneer for 280 shipped and the carver for 350 bringing my total to 620? This would be a better option than amp/preamp? keep the opinoins rolling!!
There is a nice looking ATI 1505 up for sale right now for not much more money. Definitely worth looking into for a good deal on a nice 5 channel amp.

I have no affiliation with the seller whatsoever.
