When reading all the comments referring to SPL measurements, keep in mind that SPL is referenced at 1m from the speaker, that you are 14 feet (just over 4 meters), and that SPL decreases -6bB for every doubling of distance. That means that at your listening position, your SPL is about 13 dB lower than at the 1m reading. BUT, a doubling in wattage only achieves a +3bB increase in volume. So, at your 14 foot listening distance, you will need almost 20 times the watts as needed at 1m. Also, the more watts your amp has, the more headroom, and that allows the amp to stay within the linear portion of it. ( Depending on design, an amp is only linear for maybe the first 50-75% of it's power rating. The closer you are to it's rating, the less linear it gets, and ideally, you want to stay in that linear range). Because of all of this, get as much wattage as you can afford, The more headroom you have, the better.
100 watts enough?
Hi all. I'm contemplating purchasing a CH Precision A1 and I don't know if it will drive my speakers adequately. I have EgglestonWorks Andra III speakers which are 88db efficient (impedance 8 ohms nominal, 6 ohms minimal). I have a 30x20ft room and I sit about 14ft from the speakers. I live in a condo and have almost nothing between me and my neighbor so I don't ever crank up the volume. I use a VAC Renaissance preamp that I almost never crank past 9 o'clock. The Andra III is a speaker that likes lots of power to open up. So what do you think?
