Tom Evans has this to say about his, yet to be officially released,

                      'Linear A Mk 4' stereo and 'Linear B Mk 4' mono block, hybrid amp designs.

 

'I have adapted one of the new, larger, more complex regulator PCBs, to power the input and driver stage sections of the power amps.

This further improves what were already highly rated and respected power amp designs.

This provides a further obvious audible advancement in terms of micro dynamic resolution across the amps input and driver stages extremely wide signal bandwidths'.
