Sensitivity 86 v 90

I am considering an upgrade from speakers with a sensitivity rating of 90 db, 4 ohms, to larger speakers rated at 86db, 8 ohms nominal.  Same brand, PMC. My tube integrated amp is 80-112 watts triode/ultralinear, and it’s fine for my 90 db speakers.  Although, it is sometimes at around 4 o’clock on the volume control, approaching the max at 6.  I am aware of the “amp power must double for each 3db increase in volume” rule of thumb, but really have no practical experience with this.  I do like having 90 db efficiency, always assumed that meant a less powerful amp would suffice. 

   My question is, would the decreased efficiency be a concern?

My integrated amp (Rogers EHF 200 Mk 2) has 40 db of gain. 

That is a nice amp, you have plenty of gain. What phono preamp do you have?

After all that was mentioned before I posted, I made the same, dumb mistake of citing efficiency instead of sensitivity. Everything still applies. 

All the best,

Yes it is a issue if you are pushing the volume now ,then you will be running the amplifier into its highest distortion which can damage yours speakers as well as your amp, find a speaker around 90 db there are plenty of them out there 

Even if you have to wait and save more Monies , we’ll worth the wait 

or get rid of the amp and get a bigger one.
