Krell kav-400xi with show case dvd or dvd standad?

More power is never an issue. In fact, the more power you have on hand, the less the distortion each driver will suffer. Cone control and dynamic expression will be increased as well, plus if you want to run a subwoofer or two you can use the preamp out connections on the 400xi. It is concievable that in the right room you may not need to ever change speakers.

Whoa, so this has been a total misunderstanding on my part? I always assumed wattage ratings had to fall into the wattage ranges by speakers...so not only will having more wpc than what is recommended not hurt the speakers, but it could actually help? why do speakers even have an upper limit then?

It gives the user an idea of how much power it takes to drive them and also indicates what the speakers limitations may be...in other words, more power will be cleaner and less damaging to the speakers, but you could potentially still overdrive them. Having less power will present more distortion issues, especially at higher volume levels on demanding material. Bottom line is that you use your speakers within their design limitations no matter what the power rating is...the sound generally get's flat and harder sounding as the speakers compress. For most real world applications, upper output limits should not be an issue unless your a head banger. Knowing your speaker ratings and having plenty of clean power is never a bad thing...abuse comes from ignorance and overdriving your speakers:)

Ah ok, thank you for elaborating and clearing that up :D
