Current or Previous Harbeth Owners…

NOPE!
 Only the Sonus Faber Toy Towers I had even come close to the performance of my current M30.2Xd's & even those were not quite as transparent through the midrange...

@deep_333 hahahahahahahaaa,I've seen some delusional,absolutely asinine statements on this site but yours has to rank right up there in the top 2 or 3!

The BS regarding the cabinet resonance of Harbeth is laughable..WTH do you people think a Cello,Violin, Les Paul,Strat or even a close mic’d drum kit would sound like without the body resonance?
I’ve heard VERY VERY expensive,MASSIVELY heavy,dead cabinet speakers like Krell & Magico,IMO they are lifeless & soulless!

@dpac996 ,this replier continues to parrot his "opinion" in thread after thread regarding Harbeth speakers,denigrating speakers & a maker who are cherished world wide by end users & reviewers..IF the cabinets contributed so much "coloration" as he states the WHY are they so highly regarded by EVERY SINGLE professional reviewer that has put their time & effort into providing the potential buyer needed Intel?
 Also to address this "issue" I offer the following excerpt from Stereophiles M30.2Xd Anniversary review:
" the thin-wall cabinet construction advanced by the BBC type of designs is intended to minimise such resonance, by means of a layer of heavy and lossy bituminous coating on the inner surface of the panels. Just as a car's shock absorber converts spring rebound energy into heat and stops the car from continuing to bounce long after the initial bump has passed, so this damping layer absorbs and dissipates most of the energy transmitted into the cabinet wall, thus reducing the amplitude and duration of unwanted vibration.
Research carried out by the BBC back in 1976 proved that this construction method reliably put any cabinet wall 'noise' at least 30dB below the main sound output level, meaning that this coloration became inaudible. In engineering terms, that is 'job done'.
As always, there is a compromise in that vibration cannot be totally eliminated (any more than a car can have 'perfect' ride comfort!). The effect of heavy damping layers on thin timber panels is to place the remanant vibrational modes in the mid-bass 100-250 Hz range, where the worst they can do, if faintly audible, is add a modicum of 'warmth' to the sound."

I would add one more thing..I moved from M30.1 to the 30.2Xd...The 30.1 did indeed have a touch more "warmth"that could come off as slightly veiled or too dark with the wrong amplification..The 30.2Xd does not have that additional warmth,adding a bit more nuetrality through the upper bass,lower mid range..An email to Harbeth returned the info that the inside of the cabinets & crossover received a little tuning to bring this about...
