The look of the "5" seria

Clue: each "knob" is about 80mm across...

Firstly, you did rattle my cage a bit when you said 'The best way for Naim to go..' perhaps if you had worded it 'a possible alternative would be..'?

So I am sorry if you were offended - nothing wrong here with constructive ideas - its just personally I am very very confident in the ability of Naim R and D, who I think should be treated with the respect they deserve.

Secondly, I am not a Photographer!

I'm not at all averse to the discussion of constructive ideas, indeed I thrive on them, but as an engineer I like my discussions to be based in fact, supported by evidence.

From the information I have available to me the following is true: -

Aluminium has a thermal conductivity of approx 237 W/m.K
Glass has a thermal conductivity of approx 1.3 W/m.K

i.e. glass has a thermal conductivity almost 1/200th that of aluminium.

I don't have figures for Pyrex glass, but I would be stunned if it even came close to aluminium, it's main benefit being resistant to damage from heat.
