Does Harbeth M30.1 Sound More Open That Its Predec

A new M30.1 user reported that the speaker is more open than the SHL5 which sounds laidback in comparison. My experience with the older M30 seems to be the other way round. To my ears the M30 sounds more shut-in and laidback than the airier SHL5.

I would appreciate if someone who has listened to the M30.1 can advise if it sounds substantially different from its predecessor especially in areas of transparency and openness.

Thanks in advance.
