I am claiming what I have heard - which AUdio Note system have you heard with the volume cranked up? Peter Qvortrup has been selling his high but not exceptionally high efficiency speakers with his 8 watt amps for close to 30 years and to people who generally have money and who have generally owned plenty of high power SS amps. So unless he is managing to fool a vast number of people including audio equipment reviewers like myself who have heard top of the line 1000 watt amplifiers and numerous $50,000+ horns then something is amiss.
At CAS I auditioned the Volti Audio Rival horn speakers (100dB sensitive) and with 20 watt Border Patrol amps - when pushed there was audible distortion.
The AN E/Spe He is rated as 97dB sensitive (by AN). One speaker free standing, the speaker was measured as 92dB sensitive by Stereophile (so factor in 2 speakers and in corners and in room then 97dB is accurate).
The speakers played louder with no distortion than the Volti.
In the case of the AN J/Spe - the speaker is rated as 93dB sensitive but unlike the E it presents an easier impedance load not dipping below 5 ohms.
93dB @ 1watt
96dB @ 2 watts
99dB @ 4 watts
102dB@ 8 watts
105dB@ 16 watts (AN amps can go a good 50% above their rated specs.
Most people most of the time listen at the listening chair below 80dB. It is fairly loud at 70dB. To those of us who still have quality hearing ability left that is. I could make the keyboard on my desk rumble with the OTO/J combo so I am not sure how much louder you need for it to be.
This is supposed to be about quality of music not quantity of SPL. Certainly there is a limit to what this can do - the J can after all handle 150 watts so one is welcome to buy a Rotel RB 1090 which is capable of 1kilowatt and can be had on the used market for $600. It will certainly play louder. I'm not against power - these days power is dirt cheap.
This is why my general preference is for preamp and power amp that way you can run the comparisons yourself. Have the 8 watt monoblocks and the 500 watt monoblocks and see.
Just like this video where the show runner had an 8 watt monoblock and 160 watt monoblocks. And makes not about the difference in power.
