Why are so many people trying to sell Harbeths?

That makes some sense. At least their product is worth the price. You may remember Talon loudspeakers. They did the same thing. They got some good press and immediately doubled their prices. Their speakers weren't good enough to justify those prices though, and with all of the competition, they started a slow death spiral, sold out to Rives, and ceased to exist altogether. I think Rives is gone as well.

The Harbeths at CAF sounded very nice one of the few that left me wanting to come back but gotta say the cost was a shocker for a speaker of that size.

I covered the whole show in about 4-5 hours on Saturday so could only note the rooms that caught my ear but not much extended critical listening in each.

 I popped in the larger deja vu room as well and that one did not register for me probably due to way out of any practical budget for me and not the sound I wanted to hear for that. Small rooms make it hard to demonstrate the full value of larger pricier gear for sure so not ideal for that.

The room was a nice size for the Harbeths though and I liked the sound very much.

So much competition at their price point though.

If you seek a very well made, nice looking,  good sounding product, the small size for the price point might actually be a selling point for some. I wouldn’t rule that out personally. But if you have room and WAF perhaps not an issue, then lots of competition at the Harbeth price points for sure.

There is a continuing assumption in audio that great speakers "should" sound good on any type of music. I am not sure that is totally true in reality, though it is a noble and worthy goal to pursue if you are building these

things.

..............and that assumption would be correct.
