You would have to listen to the Harbeth Super HL5 XD to learn if they are right for you. It is not mentioned in your post if you have ever heard these speakers before.
You need to locate a local Harbeth dealer , if you have one near you and listen for yourself. You can have the speakers placed near the wall behind them to experiment. The dealer might even be able to set up a home demonstration for you. The link below will show you local Harbeth dealers in the USA.

If you do not have a local Harbeth Dealer ,your next best option would to be buy a pair of Harbeth Super HL5 XD on the used market and try for yourself. If you do not like them ,you should be able to resell them for little , or no loss for what you paid for them.
