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?

It’s really easy for me to figure. My amps put out about 10 watts class A into 4 ohms. My speakers are rated at 91db at one meter and my listening position is 2.5 meters from my speakers and seeing as I rarely go past 75-80 dbs, I’m I’m class A most of the time.
