Has anyone ever switched to Harbeth

"My Dyns had to play loud to sound their best.. "

I have Contour 1.3mkIIs. They also sound best with some volume. My Triangles and OHM Walshs are probably better at very low volumes.

Allow me to gate crash with Spendor S8e or S9e. I believe spendor and harbeth are close in sound characteristics. Which one is better? And in what ways? Thanks

They seem close enough that if I owned one I would only choose the other because I was bored - that is not a big change in persepctive as Dynaudio Harbeth move would be. I do think neutrality and resolution is a house sound; that some like and others not so much; Dynaudio always left me feeling a little cold, but it could have been the SS amps that invariably drove them. OP, I think you have a sense of the difference, but nobody can tell you what you will like better; simply can't be done - it's up to you. Now I have heard both brands, and what I prefer to both is the Merlin VSMs, but that might not be up for consideration for you, don't know.

As a long time user of both dynaudio and now harbeth speakers i'd say both speakers are really good and it boils down to personal preference.As many pointed out, Dyns are more neutral, harbeths are a bit warmer.
Both speakers are capable to world class sound.
Between the two , the Harbeths are more forgiving of ancilliary gears, Dyns need good power to shine thru.
I can live with either speakers, but for the last 4 years or so, i've been enthralled by the Harbeths.

I've had many speakers, Proac Tabletts, Dynaudio 42, Tukans, Tannoy Eryis DC-1, Spendor s3e, and much more. My ears are finally so happy. Got me some Harbeth P3ESR SE speakers. No one is taking these away from me!
