How would 2 or more transistors in parallel and nothing else sound when driving a low Z speaker?

For example on a Pleiades BD139 amplifier but with more than one BD139 transistors so that output impedance lowers in order to achieve impedance matching to a say 4Ω speaker.


Other option is an emmiter follwer but this would possibly need a driver transistor to increase music signal voltage fed to output transistor.


Other option is an output transformer, see previous posts.


Other option is nothing but one transistor. It still sounds great with a less loudness capability.
