Current or Previous Harbeth Owners…

@chrys71 Indeed! Harbeth 40.x is a phenomenal speaker. It's for a select group of audiophiles who appreciate good tonality and timbre, realism, and vocal purity. In my case, the most potent combination was a solid state class A amplifier paired with a tube preamp -- best of both worlds. You'd be surprised how much more the 40.x can offer when a powerful amp takes control of those 12 inch woofers. 

@toddcowles nice post

I enjoyed a few models from Harbeth; SHL5+XD, C7ES3 XD, M40.2 and M40.3XD.
Tried them all in a few different rooms and with tons of different electronics. My favorite was the SHL5+XD in a smaller room with high ceilings; some might call it a near field setup. Not sure. In any case I really loved and appreciated the special magic well setup Harbeths bring to the table. Very satisfying speakers on the long term. I recently discovered ATC SCM40 V2 passives and I’m driving those with Moon North 761 amp. I honestly think that ATC has an even better more authentic midrange and overall tonality than any of the Beth’s I owned and listened to for months in my space. The ATC speakers scale better, have more top end refinement and sweetness. The bass is absolutely better - at least so far in my smaller space; the sealed design makes for easy room integration and awesome well defined and clear bass. The midbass energy has swing and flow to it; I could hear the limitations of the Beth’s in this area with faster music. I could sometimes hear the lossy boxes Harbeth deploys coloring the midbass. Bass ripeness or a kind of raw uncontrolled resonant thing. I will always love Harbeths and will probably try another pair someday but for now I’m super happy and satisfied with ATC. Wish I would have discovered these years ago.

good luck!

I’ve owned every Harbeth minus the 40 ( room too small ). I liked all of them and I am now using the Super HL5 plus and in my room it is perfect. Head Bangers need not apply lookin’ at Harbeth! A Cerwin Vega type speaker would be more to your liking!

At last someone mentions the cabinets. In my opinion, the thin walled, "lossy" cabinets used on the Harbeths is a major detriment. I think this applies to all speakers with this type of construction. The designer offers an explanation as to why this is a viable method of construction, but this explanation makes no sense. 

@akg_ca Why would you call the thin wall design a major detriment? Many other speakers use this design including Spendor, Graham, Falcon, Stirling, etc., etc,. It's been around for over 60 years and many enjoy BBC type speakers!
