    well if your manual says 120 rms then your receiver is 120 watts.

    Don’t worry about watts. What’s more important is current. The higher current receiver the better it is. You can have a 20 Watt amp power those speakers well. Your speakers are 8 ohm but that never stays the same. Resistance raises and drops with different frequencies. So let’s say you bought a receiver with 100 Watts per channel output at 8 ohm, if speaker impendance drops to 4 ohm a good, high current amp will be able to double its output to 200 Watts while a cheap one may only be able to produce 125 Watts (these numbers are just examples not exact figures). Another important aspect of speakers is sensitivity. Sensitivity is measured in dB. High sensitivity speaker (90dB and above) will need only a fraction of power that a low sensitivity speaker (83dB and below) would require. Check sensitivity of your speakers but in any case go for quality of watts not quanity. Some amp advertise 500 Watts but produce too much distortion or are measured on a “curve”. Not sure how much you want to spend but Onkyo makes decent receivers. If you want to spend a little more go for rotel or adcom. Used is ok too as long as they’re in good condition.

    The receiver puts out 120 Watts RMS. That could jump up dramtically if it were to start clipping. Clipping will happen when the amp is pushed to its limits. I would not push it higher than 8/10 of it’s capacity.

    The Sony speakers may have blown because their wattage rating was their peak power handling capacity. Peak power is only meant for breif periods of time (ie: a second or so). Their RMS or constant power handling was probably more like 50W.

    Your HH Scott speakers would be rated at 150W continuous and would have a peak power handling capacity of around 600W most likely. If you were to over power them the breaker would kick in anyway.
