If you want to warm up the sound one easy way is to install some warm sounding 12AT7s like Mullards or TungSols.

Apologies, You said  "The 120V power input wiring should be at least 30 AWG (it's far beefier than that in the stock kit). ". Does it mean that the required power input wiring should be changed from that in the stock kit or i misunderstood and the stock cable is fine (i am not a native speaker)?

I have already change driver tubes into Phillips (Mullards). It plays very well. I am only exploring how far i can/should reasonably go with the mods. I now understand that it is reasonable to change two pairs of capacitors. I refrain for now from doing onther upgrades (like shunt regulator ect as i do not need more clarity in sound, just maybe a bit more charm).

I am really having lots of fun with this kit. I have done Bottlehead Crack and now the Stereomour. I have a vague feeling that the 300b kit may be the next, but just want to explore how far i can go with "warming" the Stereomour as i can not afford the next kit now.

The stock cable is already very overkill for the incoming AC power, and even more so since you're in a 230V country. 

You could try some paper in oil caps to slightly change the flavor of the amp, but the differences tend to be subtle.
