Welcome to PC World forums. While the Marantz specs are impressive, it does appear that the amplifier can output more power than the speakers can handle. This can lead to all sorts of problems with pinned voice coils and mushy sound from overdriven elements. If, like me, you have children in the home and they have access to the unit, these speakers can become sacrificial. I like to use speakers rated at twice what the amplifier can supply, that way they should never get close to their wattage limits and suffer failure.

Thanks for your input
Is it possible to steer or suggest something that would be a better match?
I am only really interested in 5.1 audio.
I am the only person that will ever use this setup so if i do not raise volume past 50%
would this still be a plausible match?
This is mainly for HTPC usage and I listen at moderate levels.
I like the small footprint of the Marantz AV.

Would this be a better choice with same Fluance Speakers?

DWJ: That does look like a better match but if you have enough restraint to keep the volume levels resonable, the original specs will do well too. I can't count the pairs of speakers that have suffered the rigors of pre-adult users. My main front pair are from AR and gauranteed not to burn out. Thirty years latter, they're still working very well. The rating is stated at 200 watts but when they were demonstrated to me in a show room, the salesman took 110 volt from the wall outlet straight into the speaker. Very lous hum and vibration but no smoke. That made me a believer. I use a pure surround, just four speakers, the rears being a pair of ancient Pioneer CS-100. I took two weeks of working with the placement and room treatments (wallpaper & drapes) to get the right combination. A true surround system will make you look towards a sound that isn't there. That is, the sound comes from where there is no speaker. Many systems have multiple speakers, center ones and sub-woofers but only make up for what can't be duplicated by the average user in their envirionment.

I emailed Fluance about matching their speakers to either Marantz AV Receiver
and this is their reply to me

"Good morning,
Thank you for your e-mail. Our Fluance speakers are compatible with pretty much any receivers, as long as the wattage per channel meets the standards on the speakers. This particular system, the AVHTB speakers have a minimum power wattage of 40 watts per channel, and a maximum, I believe of 120 watts. Therefore, the minimum you'd want for your receiver is 200 watts on a 5 channel system. (minimum power requirements). I would suggest that a 400 watt receiver would be ideal, but anything within that range should be great.

As for the name brand, it really doesn't make a substantial difference; we usually suggest a Harmon, Denon or Onkyo receiver, but I'm sure this one will work well too.

I hope this resolves you inquiry. If you have any further questions, please don't hesitate to contact us directly.
Best regards,"

Do you concur with this assessment?

Marantz 1403 is 50W per channel I think so would that be a total of 250 watts?
And would that meet the minimum requirements?

thanks for any input I am still not clear as to what to do here.

[mjd420nova]

Those are nice specs, which implies the no sub-woofer is needed, just a large bass of 12 inches. Most units are prone to have lower wattage for the rear speakers and only a sub-woofer preamp output, meaning another free standing unit. Many combinations work but the true test is in the working environment.

To be honest, my experience in audio has taught me that more damage is caused to speakers by lower powered amps which distort when used towards their maximum output, than with more powerful amps like the Marantz NR 1603 which has 50W x 7 into 8 ohms :-)
