I've decided to go down the route of getting a clean and powerful amp - not necessarily 'neutral' but something that can serve as a blsnk canvas - and relying on preamp pedals for colour.
I've realised that my Tech 21 Leeds and VT pedals give me the tone that makes me happy, and for more modern flavours I use Warwick/Spector and Darkglass. The wonders and ease of modern technology.
That said, the new GK Legacy heads are very tempting...
