I have a sony dh750 reciever, an onkyo dxc390 cd player and klipsch rb81-ii's with two klipsch r115sw subwoofers. According to the Sony manual I'm sending 290 watts to each speaker because I'm using the bi amping feature. I don't belive that because it's a $350 reciever and to get that power elsewhere is 10x the money. Should I upgrade my reciever to better my speakers?

If you are "biamping" your speakers by sending 2 of your receiver channels to the speaker by removing the speaker posts and hooking them up, you are probably just wasting 2 channels and not really benefitting. The amp will amplify each channel from 20hz-20khz. Then you send say 100 watts of 20-20k to each speaker. When biamping the way you are doing it, the lower speaker receives 100 watts 20-20k and its internal crossover allows the speaker to receive 100 watts from say 20-3000hz. Then the second speaker receives 100 watts of 20-20khz and its crossover discards 20-3000hz and the speaker receives 3000-20000hz. This results in each speaker seeing 100 watts. If you stop biamping, then you send 100 watts of 20-20000hz to your speaker, the internal crossover allows 100 watts of 20-3000hz to go to the lower speaker and 100 watts of 3000-20000hz to go to the upper speaker. So it's basically the same thing.

Thanks, do you think a quality integrated amp (yamaha as801) at 100wpc will be a noticeable upgrade from what I have? Or any other recommendations? I just feel like a $350 reciever with $800 bookshelf speakers seems off, like I should invest more into the amp.

Honestly it probably won't really be noticeable upgrade either. You may be better off saving money until you can just buy a better receiver someday.

Have you tried mounting your speakers the ‘correct’ way up - the HF waveguide is designed for use with the speakers in a vertical position.

The Klipsh do not require huge amounts of power but would benefit from a higher quality amplifier.

Yeah I don't notice any difference. I lay them down so it looks more old school like a big cabinet speaker.
