Listening to the 3 channel Buckeye Purifi and...well, my ears are truly ringing now but tonight managed to get the red clipping light to flash (intermittently) listening to some vintage Bowie-"Station to Station". I was surprised that the light illuminated, even briefly, as the F208's seemed to be handling the power well. Now I wonder if I need even more power... I have a rather small room and the listening position is too close so if/when I move and have a deeper room I may have to consider something more powerful. Wish I had a calibrated dB meter. Can one use the UMIK-1 and REW to measure sound pressure? The cheesy phone app read 89 dB but it seemed a bit louder than that.
If you need to make your ears ring in order to make it clip you probably don’t need more power

hence the comment about having a larger, deeper room in the future... I sit very close to these F208's (right at 8 ft) so expect to need a bit more power for HT in a larger, deeper room.

Are you using a subwoofer(s) and/or how deep do you have the crossover set for the F208s?

Yes-2 subs. Crossed [email protected] 80 Hz. I listened with subs using Dolby Surround then without subs running straight through the Freya+>Buckeye Purifi (using 2 of the 3 channels)>F208s. Got the clipping indicator to flash briefly using either set up but the light only flickered. Any louder and I would have had to use rear plugs. Despite the flickering the sound wasn't audibly distorting.

Got it. I would wait and see if/when you move to a new room. For HT use I doubt you would have an issue if you have to push it that loud using music (which is a more continuous stress then dynamic HT tracks on average)
