I also have a question after our SoCal meet at dpowell's (Doug's) place yesterday. I took my entire 2-channel system (sans tuner and antenna) down so that I could try some of his individual pieces (his Anthem tubed amp, pre and Marantz CDP) in my system. Basically we were trying to locate the weakest link in my 2-channel chain so that I can begin to plot my next move. Unfortunately, I'm not sure we found it.
But here's my question for those who are particularly familiar with Lsi9s and have tried a number of different power sources with them at some point over the years.
I am currently driving them with a Parasound Halo A23 amp rated at 200 wpc @ 4 ohms. No complaints at all with the musicality, soundstage, etc., but hypothetically speaking if I was to stay with the same line (Parasound Halo) of amps but move up to the A21 (which is about twice as powerful, 400 wpc @4 ohms) would this most likely improve the performance of the Lsi9s? (i.e. improve clarity or some other aspect of sound at lower listening levels)
I guess there might be two schools on this:
1) No, 200 wpc is plenty of power for these bookshelf speakers already, so everything else is extra and will be unused, redundant. (i.e. a waste of money)
2) Yes, the Lsi9s are such a power hungry speaker that doubling the amount of power from what I have now (with all other things equal) will definately yield better performance.
Any experiences that speak to this quandary? All opinions welcome.
