you were saying your prefer solid state amps for low end duties...
but what strikes me is that many solid state amps have the functional characteristic of delivering less power as the secondary's load impedance increases...
how many times do you see Sand State M10,000 delivers X number of watts into four ohms but only half of X into eight ohms...
just goes to show that after a 100 years of tubes and sixty plus years of sand... we've still not achieved technical nirvana.
But things can sound damn, damn good and I still enjoy listening to music.

Mikey, that's just Ohm's Law. A solid state amp is a voltage source, and it's maximum output swing is strictly limited by the power supply. Apply an identical voltage to two resistors, and the larger value resistor draws less current. Less current - for the same voltage - dissipates less power in the load.

Buy Chinese. Bury freedom.
with its multi-tap secondary applies more voltage to the larger load...:)
The other side of that SS example is that when the load is halved power doubles( assuming its PS can deliver the current ). So, n Kw into 8R leaves you with 2n into 4R, and 4n into 2r...and of course n/2 into 2R.
