I could just post a "+3", but I'll try to explain.
" tls49... going to listen at higher levels and will see how many lights illuminate. I was at only 10 o'clock volume the other night and 4 of the lights lit up. "
When that 4th light blinks, that means the amp is peaking at 20 watts of output power. Now the 3020 can peak at least 40 watts and a little higher depending on the load. So, the above scenario is well within it's operating range.
The sensitivity of the ELAC Debut B6 is spec'd at 87db, but as I said, that needs to be adjusted to 85.5 db because it's a 6 ohm speaker. Stereophile actually measured it at 85db. That's 10db lower than the Klipsch speakers you are currently using. That means the B6 will require more than 160 watts of peak power to play at the same volume of the above scenario with the Klipsch needing 20 watts of peak power. Do you actually think the 3020 is capable of peaking more than 160 watts?
So, +3 huge mistake
