Ok, I already know this is a tough order but I’m going to try anyway. I’m planning a purchase of a single ended DHT amp or monos. I’m undecided on whether the power output of 2a3 or similar triode will get me the kind of power for my desired listening level, or whether the increased power of a 300b will be required.
I’m already aware of my speakers sensitivity (about 98 dB/1 meter/watt, 8 ohm nom.) and I’ve read plenty on the power requirements of such sensitivity. What I’m more interested in here is this: My current amps are both about 15 watt/chan into 8 ohm and provide plenty of power for me. I’d like to be able to estimate approximately how much of those 15 watts are being used at a given listening level so that I can judge for myself if 2-3 watts of clean power is enough or if I need 7-8.
I don’t have any lab equipment, just a DMM and I could probably get a dB meter rigged up with my phone or something. Is there a method here in which I could estimate about how much of those 15 watts I’m actually using with a bit left for headroom? Perhaps a decibel reading and some math?
I’m all ears, so to speak....
