Would a Adcom GFA-555 that is rated 325wpc @ 4ohms be too much for the LSi15's? Thanks..

    I have 265wpc @4 ohms right now into them and they sound great. I was thinking of stepping up my game a little..

    Don't get caught up with strictly specs. I have 30wpc and it far out performs anything else I have ever owned regardless of wattage.

    Good luck

    If it's additional volume you are after, there's no audible difference between 265w and 325w. It will be less than one db.

    I hear the GFA 555 original is the best sounding version. What is the difference between the original and the newer one?

    Just wanted to know. Is it possible to wire them into a 4ohm load on my RTi10's?

    Why? It's not like they'd be louder at 4 ohms or anything like that. It would just be presenting itself to the amp differently.
