How do the cleans on the HRM compare to those of the normal OTS?

I know the main difference between a HRM and non-HRM D'type is the extra tone-stack in the OD side of the amp, but has Nik changed any values that affect the clean side?

I'm very soon to be getting a new amp and am absolutely torn between the OTS, OTS-HRM or a Fender Vibro-clone.

Basically, will I want to get a big, warm, pristine hi-fi clarity clean sound out of the amp. Not too bothered about OD sounds as I'd largely use pedals for those, but I've heard that HRM d-types get closer to Marshall OD sounds, so that would tend to push me in that direction, but the clean tones are much more important to me.

PS: I'm a strat player....

he has hiwatt clones now as well if your into the big cleans, obviously a model favoured by a certain black strat guitarist.
