Please help - it might be that the amp is fried? It is not the speakers as I have tried different sets of speakers and speaker wire and still get the same fault. I am using a ten year old Marantz hi-fi amp. The amp has been great for years however this fault started a few weeks ago and makes it unuseable.
The cost of a repair is bound to make buying a new amp a better option, however I am loath to throw out this amp as it still looks like new and in all other aspects is great.

Thanks so far - can I just make it clear - it is not the speakers or the speaker cable. I have checked and changed all speakers and cables. I appreciate that a repair shop could do the work, however their minimum charge + any parts could make the purchase of a new unit a better option. Anyway thaks so far!

Fuses are cheap. Are they all okay? Before tossing it,
why not look inside (unplug) to see if there are any obviously fried parts, which a trip to Radio Shack can replace. Is there a vocation high school with an electronics class that may have a go at diagnosing it?
Is there a newsgroup on this or similar amplifiers? The same part always seems to go...and a little soldering could fix it under $10. From the way you describe it, it could be a capacitor problem, if that helps. Ham radio operators know a lot about amps, too. A local ham club?

I would suggest, since if it's not in your best interest to repair it (did you receive a repair quote?), I would recommend selling it AS-IS on eBay, Craig's List or somewhere else, and replacing it with a new amplifier.
Actually, 10 years is a decent amount of time to get your money's worth out of it, so maybe it IS time to cut your losses and get a new one.
Not knowing which model your Marantz is, I don't know if your amp is a power amp, integrated amp, or a receiver, but I can recommend a several choices at respective price points for you to consider...
Under $250... Beringer A500 Reference (2-channel power amplifier with dual discreet stepped attenuators -I have this one and it performs well)
Under $300... Onkyo M-282 (2-channel power amplifier)
Under $600... Arcam DiVA A65 (2-channel integrated amplifier -I have this one and it is super musical)

If you've changed speakers, input source etc. and it's always the same from that channel, it could be that a component in the power amp stage has fried, like a output stage capacitor.
It might be worth whipping the top off and seeing if anything is obviously burnt or melted / distorted by overheating. If so, it might be a relatively easy fix by a repair shop... good luck.

Could be something as simple as a bad connection somewhere, but it could be that the amplifier itself is bad. Best bet is to find someone who services electronic items near your place and ask them to take a look at it. If all it takes is a quick solder connection or some contact cleaner you'll probably spend $25.00 to $50.00 and get your amp back in nearly new condition. If not, at least you'll know what's wrong and whether it's worth it to get it fixed.

first change the speaker to the other one to know if the fault is from the changed speaker or the amplifier. try to change the conecting cable too. if there is no changes the problem is from the amplifier output circuit, it is beter you refer this service to a competent technician because it might be dangerous for you to do if you are not trained in this field. the amplifier output circuitry has to be check for errors and replace the faulty component e.g amp/ic, capacitors e.t.c

take it to a hifi repairers and ask them to check the 'mini' fuses, which are built inside and the output ic's.. one of those is at fault.. maybe time for some new/fresh speaker wire,,(Qed silver anniversary will make it sound so much better) g luck
ps: check your +/- connections on your speaker wire.
on quality wire, the writing on the wire is a direction indicator follow the flow...
