@OP Re Boomerbillone's post. It is a little misleading to tie references to distortion to the output devices. Class A operation avoids crossover distortion. However, amplifier distortion is influenced by a whole host of factors so you can still have a Class A amplifier that distorts. There is also the fact that because true Class A amps are inefficient, they may need to be driven harder to achieve high SPLs and thus increasing distortion. That is not to dismiss the benefits of Class A operation - it has a lot going for it when it comes to reproducing music.
Class A bias, speaker sensitivity, watts...?
Hello
Please help me understand the relationship between Class A bias and wattage output. I recently bought a used Vincent Audio SV236MK used for a great price. The specs state 150 watts into 8 ohms, 250 into 4 ohms, and the first 10 watts being Class A @ 8 ohms.
My speakers are Sonus Faber Lumina II which are rated as 4 Ohm with 86db sensitivity. Everything is set up in my small cube shaped office. I used a DB meter on my iPhone and found that when I turn the volume up to what I consider to be "loud" the peak measurement I get is 80db and under.
Given the specs above, am I hearing mostly/all Class A watts while listening?
