- Sounds contridictary, but it is sort of an apples and bananas comparison.
- I've heard that the Sony's like those sound ok as long as you don't demand
- too much from them (like driving a 4 Ohm speaker). A "quality amp" will
- deliver 50% to maybe 100% more power into 4 Ohms than it will into 8 Ohms.
- There is a huge marketing war in consumer audio - especially to get 100 WPC -
- so mfgrs seem to be doing just about anything to get that magic number.
- The worst trick I've seen is "for driving 8-16 Ohm speakers". This tells me
- that I'd almost cut the power output rating in half when comparing it to
- "real" amps that rate 4-8 Ohm loads. Real expensive, quality amps will
- drive 2 and even 1 Ohm loads.
-
- The best way to see if the amp AND speakers will work for you is to listen
- to them both with a few CDs of the most demanding music that you like. Your
- ears will tell you the answer. Just make sure that if you can't listen to
- both together before purchasing then you can return it with FULL REFUND (not
- store credit) after a week or two.
