You gotta find what u like with your own ears and fine tune it, if that's using solid core vs stranded.. or Sozo Coupling caps rather than Orange Drops.
Or changing the 2n2 cap to 3n3, 4n7, 5n6 etc.
Tried using 47nF on the PI rather than 22nF?
Tried using a mixure of Polyproplene vs Polyester caps? Maybe a 500pF Ceramic cap rather than Mica?
It's endless I've tinkered beyond all belief with this kind of stuff and I agree with Ken about peoples hang ups with OT's and stuff u can make just about any OT sound good if you spend enough time with it and tweak it.
Or you can copy the 'right' schematic perfectly and every single aspect of Kenny's design might work for you
