The opposite is true for Class D amplifiers, some of which choke when I am wondering if it's OK to run a pair of 8 ohm (custom made ARs) and a pair of 4 ohm speakers (Celestion 15XRs) on the A+B setting of a Yamaha A -S501, set at 'low impedance'? The result is a pure signal with minimal distortions. Neither is worthwhile IMO. Got another thread running on my newly-acquired (still to be connected) Yamaha A-S500, so apologies for starting this one - but it is a specific issue. VOLUME controlIncreases or decreases the sound output level.12. where demands for power are relatively small.
