Harbeth 40.3 XD versus Harbeth 40.2

I have spent time with 40.2 AE and the 40.3XD.
 It’s as though the .1 to the .2 has taken a small step again. XD has a tad more detail and the bass seems a tad tighter.  It’s as though the tweeter is playing a bit further down. It’s very subtle change but it’s noticeable.  AE is just a bit warmer ( ever so slightly).  I would say the upper midrange had a tad more detail ( touch more dynamic). The XD is appropriate description. 
 Both are just fantastic. If your room presents a small degree of rumble good chance XD may solve that.  Again subtle but noticeable.  Not a review expert but I’m a Harbeth fan. Trying to help out is all. I own Wilson and Rockports and would never be without 40.2AE or 40.3XD. I won’t disclose which one I kept. I will say that either  one is fine for me.  

Very helpful. Thank you. Makes no financial sense to "upgrade". My 40.2's are awesome.

Sad to see that who was a down-to-earth manufacturer of very good speakers has fallen into the Anniversary/DX/SE edition bullshit. 

I have 40.2, 30.1 an P3esr, happy with all of them. Those came from a guy that wrote about the development process of each model... Harbeth post summer 2019 is almost a different company owned by a "different" Mr. Shaw.

What audio company doesn’t upgrade and offer new development? The Harbeth 40 series is not outdated or obsolete at any series level.  Each iteration is different but not improved iMO.   One may prefer a series that’s older. Your equipment, room, and personal taste is the determining factor.  If you don’t own a pair of 40s and want new only then 40.3 is your only option once AE’s are sold out.   .2- .2AE or .3 are all just amazing. You simply cannot go wrong, as differences as all so small. 
 I’m glad Alan has created them and will never be without my set.
