If I use light throttle I don't get the noise at all, only if I put foot flat out which in fairness I rarely ever do this, just so happened to do it last night and noticed the noise and now I'm paranoid about the noise haha! It's a bit like when you have a mouth ulcer or broken tooth - you can't stop sticking your tongue in it once you know it's there!!!
I will have to test it in my other Jazz as it's identical to mine and if it does it in that one it's likely not to be an issue.
Car is running generally fine otherwise - I do get a clutch judder when pulling off when the car is cold, seem to have to apply more revs to eliminate this (2k+ or so) but when the car is warm the judder disappears and I can pull off at 1.5k revs as normal. Honda dealer couldn't find a problem when they inspected clutch, flywheel and gearbox but my other Jazz doesn't do it? Kind of lost faith in the dealer as they treat you as a nuisance in the hope that you will give up, disappear and stop 'nagging' them if they don't do anything for you.
