OK may be a dumb question, but could you use resistors to up the
resistance of 4 Ohm speakers so they could be driven by a 8Ohm amp???


**Sure. Make certain your resistors are rated for half the power of the
amplifier though (they may get very hot). Damping factor will go out the
window and you'll throw away 50% of the amplifier power, but it will
work.

Personally, I don't see any value in buying *any* amplifier which cannot
drive at least 4 Ohm loads.


An autoformer would work much better.


**Oh, please! Adding an autoformer to a solid state amp, is like sticking a
fifth wheel to a Porsche. It is MUCH cheaper and far more effective to
increase the SOA (more output devices and heat sinking) of the output stage,
than adding kilos of iron and copper. Autoformers (in 2006) are a waste of
time money and mass. Transistors and aluminium (or fans) are cheap,
effective and light weight.
