Lord Valve Speaketh:
First of all, a 16-ohm cabinet *cannot* be rewired to 8 ohms.
It can be wired for 4 ohms, or 64 ohms (not useful) but not 8.
If by "produce better" you mean it would allow the amp to deliver
more wattage, this is only true of solid-state amps...most of
which ship with 8- or 4-ohm cabinets anyway. For a tube amp,
as long as the output impedance selector is matched to the
impedance of the cabinet, the power will be the same at any
impedance. Running a tube amp at 16 ohms is advantageous on
two counts, however; first, it allows the amp's power to be
developed across the entire output transformer secondary winding
instead of just a portion of it, as would happen with an 8- or 4-
ohm load. Second, the higher impedance minimizes the effect of
speaker-wire resistance, thus improving power transfer.
