Amp & Speaker matching

R Burke,
In my opinion the higher the speaker impedance the better for tube amplifiers,i.e. easier load to drive and generally less distortion. You should not have any problems.Low impedance speakers can be a 'potential' problem for some tube amplifiers.

Hi Al,
I agree that the "light loading" principle is likely to yield varied results and is amp dependent. For example my amplifier has an 8 and 16 ohm speaker tap. My speaker is 14 ohm nominal load and 10 ohm minimum. Without question the sound is better at the 16 ohm tap rather than the 8 ohm. Simply put all music reproduction parameters are just better.I understand that the Music Reference amplifiers could be a different situation and thus benefit from the light load appraoch.If there`s loss of power it unnoticeable, the sound is actually more transparent/open, dynamic,with increase scale, fluidity and flow.
Regards,
