3WPC? Am I reading that right? My bookshelf speakers are 75W apiece, what's the point of this?
75W/channel is the maxium power your speaker can handle before it get destroyed, it doesnt mean it'll use 75W at normal listening volume. It depends on your speakers's sensitivity, let's say it's 90db, that mean 1w/channel amp 'll get 90db maximum from your speakers which are 1m away from you. Normally people listen to around 70-90db, that mean 1W/channel get you quite far with high sensitive speakers.
Another thing is that 75w/channel amp wont get you 75 times louder volume compare to a 1W/channel amp, because for each 3db after first watt the speakers need double the power, that mean 75w/channel amp only get about 108db maximum with 90db speaker.
High wattage amp give you more headroom for dynamics, but the amp quality mostly lie in its design not how much watt they put out.
Hope that help.
75 watts is a recommendation, do you know the sensitivity of the speakers?
yeah, they're 85 dB 1W/1M.
85 is very low sensitive, all hifi speakers are in this range, if you want to drive with tube amp, you'd get a 95db speakers. and most of them are full range or horn speakers.
I used it with bookshelves in the sensitivity range and surprisingly it can get pretty loud.
2watt can make lound sound, but depends the music, if very dynamic music you may have disorder sound at the peak, but most people may not notice it.
although it's generally not a great idea to push your amp at full power all the time
Mine are about that. This amp gets my speakers loud enough to disturb my downstairs neighbors.
