Speaker Efficiency

   I have been listening to my Decware 300b tube amp for a few months now. At 8 watts, I have them paired with Klipsch Forte IV at 99db efficiency, and this set up has been sounding great. This morning I connected a pair of Sonus Faber Electa Amator speakers, 6ohms at 88db of efficiency. They sound fantastic, with more weight  and depth. I understand there is a huge price difference in the two speakers, but aside from that, if I am getting 80db of volume at my chair, 8' away, what is the draw back of using lower efficiency speakers with SET amps, so long as the volume is sufficient? I did notice turn the Pre amp, the tube amp and the Roon volume towards the highest setting, it starts sounding terrible....

Probably none.

If it were solid state amps you would probably hear a big difference. Solid state amps are so fast to react and sound very bad when they run out of current. I have a friend with a Pass amp kit… 8 wpc. Sounded great until any volume and then sounded anemic.

80db is pretty loud. My average listening is done between 65 with peaks to 75… seldom more.

 

Yes the Amator is a great speaker. Of course, more power would likely result in even more dynamic sound.
