In the last week I have gone on an upgrade binge, and here's my current setup which will preface my questions.
Denon 4802 (125 watts per channel, not rated at 4 ohms however)
The upgrade I did was replacing my RTi8 mains with the LSi15's and the CSi3 with the LSiC. The difference is astouding in 2 channel music (set the receiver to pure direct for music) and in movies after an hour or two the center really opened up and I just love it.
A couple questions for you.
1.) I know I'm not pushing 4 ohm power to the speakers. From my reading on the forum I have come to the conclusion that I'm missing out on a LOT of good sound by not powering the lovely things very well. This must be rectified! (but on a budget ;))
2.) Is it possible to power them "too much"? IE: the LSi15's are rated at 125 watts according to specs... if I push over that can I damage them? If so, where do I draw the line in the sand in terms of power?
3.) I'm looking into a couple options for amping those mains. First option is to simply use the preamp outs on the Denon AVR 4802 and put in a B&K reference 125.2. This will push out a rated 185 watts at 4 ohms. Another option is hooking them up to my roommates 200.5 reference and reference 30 preamp and try that out because he ALSO has the upgrade bug and I may be able to buy that setup from him. His setup would push an incredible 375 watts at 4 ohms. Whoa. Is that too much?
Thank you all for taking the time to answer what you can, I appreciate it!
