Speaker power handling


I'm currently demoing some Dynaudio Focus 140 speakers rated at 200 watts rms/iec @ 4ohms.
With my older PSE amp rated at 195 w@ 4ohms the sound is good.

Now my concern is to try my Classe CA400 that is rated at 800w @4ohms without having an expensive repair bill. I do at times listen at higher volume settings with peaks around 95+db.

Should I resist temptations trying the Classe?

Ok then, this makes me a bit more confident to give it a try.
Previously driving my Magnepan 3.6r's with the Classe didn't seem to be enough power.
I'm aware of too low of power and clipping resulting damaging the tweeters, and sometimes too much power melting the woofers.

I read a few online articles that were more orientated towards dj's/pro audio and thus my concern with 4 x the recommended power of my amp.

Thanks for the replies
The demo of these tiny monitors was to get a sense of the Dynaudio house sound without lugging around their larger series floorstanders.
Although small, they sound surprisingly larger and for a 2 way design they are very coherent.

Shadorne: Thanks for pointing out the 80hz. hump as there was something going on in that region that I just couldn't figure out. Although with a 3 foot rear wall spacing for the rear port it wasn't standing out.

My room is about 17x20x8 leading to an open hallway with diy Owen Corning absorption panels on the side and rear walls.
My main criteria is for smooth midrange and high frequencies so I am open for other suggestions without spending over 3k. My Magnepans just didn't work in my room.

I've been doing this audiophile stuff for over 25 years and only 4 speakers have been in my setup. I have not been exposed to many other brands so Audiogon is a good resource for information and appreciate the feedback so far.

My listening distance is around 9 feet with nothing between me and the speakers. Several months ago my tiny Paradigm Titans were destroyed with too much power applied so I chickened out trying it again.

My local dealer also carries B&W, Audio Note,Harbeth and Sonus Faber amongst others. The Audio Note E's just did not fair well in my room with various tube amps resulting in boomy bass. So my quest continues!

My source is a Mac Mini with a Sim Audio Moon 300d dac.
Thanks again for the replies. Another speaker in my current home theatre setup that I have dragged into my 2 channel system on occasion is an older pair of Paradigm Studio 100 v2 speakers that just crank and sound fantastic for the first 10 minutes. Then listening fatigue sets in with too much of a forward sound and harsh HF.

My Classe amp drove them with ease. If I could find similar performance with smoothness my search would be over.
These ATC speakers look interesting. Is there a dealer that carries them in the U.S. or Canada?
Vandersteen 2ci's since sold, were in my system for over 15 years. I'm not if the newer signature versions are more alive sounding as my 2ci's were a touch boring but polite.
The Classe has been sitting idle since the sale of the Magnepans thus the temptation to try it.

My last audition was a single driver speaker with an 18w set amp. The midrange was fantastic but lacked dynamics.

I'm hoping to try something different this weekend after another visit to the dealer.
I'm using my old PSE amp because of the lower power and easily within the limits of the Dynaudio without worries.
With fussy speaker loads the Classe easily bests the PSE including the Bryston 4bsst.

Dynaudio also distributes the German made Octave tube amps which I'll borrow this weekend along with hopefully a larger Dynaudio speaker.

As suggested, these monitors may be to limiting for my space and requirements.

thanks,
I think they only have the 40 watt integrated on the floor. I have tried it at home before, paired with a single driver 94db. efficient Fostex speaker.

It will be interesting comparing the sound with this amp driving a 4 ohm load of the Dynaudio. I'll then try the Fostex speaker again for a back to back comparison.
