A move from Harbeth to... Wilson?

 For investment in that league, would make sense to listen more widely before making the jump. Consider Vandersteen Quatro Wood CT at substantially less cost than Sabrina X. Sound to my ears is more lifelike than Wilsons.

Geoff won’t like this but i had two 60-90 minute demos with the Sasha Daw in Manhattan this past July and found the $37k speakers too dry and clinical to my ears. Although on the plus side great soundstage, imaging and super clean as I could hear every lyric (which is a problem for me as I have asymmetrical hearing loss), it just tired me out. It had no soul to me. Meanwhile I wound up with the Harbeth 40.2 Anniversary and absolutely adore their warmth and natural sounding musicality. Vocals are liquid smooth.

Wow, thanks for the great comments and discussion. In answer to a few queries, I do love the Harbeth "sound" - the natural midrange and overall true timbre. (I'm a musician, and timbre is my #1 concern in any speaker and system.) That said, I have found the Wilsons to be less analytical and clinical that some have suggested, and similarly natural and timbral-accurate. I don't necessarily think they're a complete dichotomy, but perhaps I'll reflect on that a little more.

To address what I don't like about the Harbeths, that would cause an upgrade "itch" to be scratched? It's hard to say - they do from time to time sound a bit "boxy" on big, orchestral stuff. But overall I have no complaints, just... an itch for something different, maybe? Complacency = first world problems! :)

And I think my room is probably a limiting factor for the big Harbeth 40s, though with the overwhelming consensus on those, I may do look at those calculations again. Moving up the Harbeth line does make sense, I just think that's too much speaker for this room, but perhaps it could work? Hmmm...

The Wilsons are an order of magnitude better speakers. They are the lowest distortion, most dynamic and resolving speakers, the most lifelike speakers anywhere near their price. Anyone who thinks they are HiFi sounding has not listened to current models, or has listened in systems with those horrid flat cables, or ones with high silver content, to through the horrific DACs from PS Audio or Mytek. Or simply hasn't heard live music.

Hyberbole
I doubt an order of magnitude separates many different speakers, unlike the pricing.  In case you don't know, an order of magnitude is 10x.

Exaggeration
At that price there will be plenty of other options.  Anyway we all know speakers are a very personal choice.

Silly supposition
And can any member who 'hasn't heard live music' please put up hand, there won't be any.

The above post adds nothing and we can all do without.
