Is my onkyo sr806 enough power for these or would getting a seperate amp make a huge difference?
wouldnt the onkyo and a preamp be overkill? because doesnt the preamp put out its own power so all the power in the 806 is useless?
im kinda confused on the whole seperate amp and if it is worth the money...my little budget would be like 500 bucks even used.
Hmm, you've got me a bit confused. Forgive me if I'm not correctly understanding your question.
Is your Onkyo an all in one AV receiver? If so, that would function as your 'pre-amp' if you purchased an external power amplifier.
If your Onkyo has 'pre-out' jacks (RCA output connectors) on the back of it, you would connect the left and right (or L, R, C, RS & LS if you buy a 5 channel amp) via the RCA (un-balanced) 'pre-out' connectors to the external amplifier's RCA input connectors to power either two, three, four or five speaker channels depending on the aplifiers capabilities and what you're looking to do. That turns your Onkyo into a pre-amp or rather, you'd be using the pre-amp section to send the audio signal to the power amplifier.
Your Onkyo SR806 has adequate power for your current set-up however, more power is always better.
As opposed to just the 'adequate' power of an AVR receiver like my Yamaha RX-V3800 (140wpc X 7), I wanted REAL power for my L/R (main) speakers for two channel music listening so I added a power stereo amplifier (300watts minimum RMS per channel) to my Yamaha AVR. hopefully in the not too distant future I'll be adding a three channel amp to power the center and surround channels as well.
I live in a pretty large studio apartment and the Yamaha AVR just wasn't giving me the dynamics my speakers are capable of in my living space. After installing the external amp, I'm able to play music at realistic levels without sacrificing sound quality. No compression or hampering of dynamics because the external power amp has way more than enough headroom and power to drive my main speakers cleanly even at high volume levels.
Thats what most people are after when they add a power amp to their system. Good, clean and dynamic power.
Hope that somewhat long winded explanation helps and actually answers your question.
