Question about higher power hybrid amplifier output stage




Hello!
M friend has given me a suggestion about paralleling more 2SK1058 for higher power, the attached circuit capable 90W if operate at 50v @1.2A, what would happen if adding 2 more pairs?

It will lower the distortion, lower the impedance, right?

Does the driver stage able to drive 3 pairs of 2SK1058??

What is the maximum pairs of 2SK1058 the D3a able to drive??

Thanks!
