+1 for "how big is the room"?
I had the Harbeth 30.1, 35th Anniversary speakers in a smaller room and the midrange is very pleasant and the upper bass is tuneful.
In my slightly larger current space, a medium sized 18'x14' room, I now have the Spatial Audio Labs M3 Sapphires. These do everything better than the Harbeths, but only if you can bring them out at least 3 feet into the room and sit about 8' back from them.
The Sapphires have open-baffle bass from two 15" professional paper cones. The depth, timbre, and texture of bass is amazing. It is realistic and palpable and true to the source. The midrange detail and openness is better than the Harbeth's and with a tube amp or preamp can convey even more emotion.
The M3s are $5k new and they are made in the US.
If you are in the DC area you can audition the Sapphires at Linear Tube Audio up in Takoma Park, MD. Nicholas will cue up whatever music you like and is very helpful and low key. Their listening room is the shop front for the workshop where they build their tube amps and preamps. It's lot of fun to visit, and they are music lovers and musicians (in many cases).

But the open-baffle bass from the Sapphires (and other Spatial Audio speakers) is just a different and more natural sound. All box speakers sound like boxes after hearing open baffles.
