I don't think there is any obvious negative correlation between the number of output devices and sonic purity. There are a lot of performance gains from paralleling output devices, e.g. lower output impedance and higher damping factor without using more negative feedback, better performance and stability into lower impedance loads, more power, possibly even lower distortion if it results in operating the output devices in a more linear region. Component tolerances are critical even if you have a single pair of output transistors per channel. I don't see why the tolerances need to be tighter if you're using 16 output devices per stereo amp vs. 4.
