Thanks guys, I've looked into the headroom amps & I have fired off an email to ask their recommendation.
For films I use kef Ci eggs & a big Rel sub, it works brilliantly for that, but if I play music through that system I start to really pick holes in them, midbass & integration really suffer, but then I can't afford an extension on the house for a dedicated music system, one day I hope to be there…

Cheers.
