Hello,

I recently just bought my first pair of good loud speakers in the B&w 683's. These are a huge step up from my previous cheap Klipsch bookshelfs. Before I purchased the system I kind of went the backwards way about it and purchased all the extra source equipment knowing that one day it would be for a great pair of speakers. Just to give you an idea I currently have for music:

Onkyo TX-SR707
Pro-Ject DebutIII
Oppo BDP-83

now this system is going to double as my television system so would also have:
Tivo Premier
Xbox360
PS3

So after opening the speakers and breaking them in, I started to feel like it was lacking something. The bass extension wasn't as low as it had been in the store and something about the midrange seemed off for some artists vocal's. My first assumption would have to be that the speakers are being under powered. The Onkyo lists as being 100w/channel but I am fairly certain that is not what I am receiving on the speakers.

So my question is what can I look for, in a decent amplifier around $300 that I can connect to the pre-outs of the Onkyo. I know that this is not optimal but currently I do not have the money to invest in a whole new preamp/amp combination. The b&w's are rated up to 200w a channel.

Does anyone have experience with these speakers as well as what they may be amping them with?

Thanks

Sean
