Have been a fan and user of British speakers since late 60’s. Unique Sonics that have always appealed to me.
i own Spendor ls3/5a, SP1, and Harbeth SLH5 plus, as well as 40.3 (endgame) for me.
Not sure I could group them by brand. Each is unique, and totally wonderful. Currently listening to SP1 at my summer home. Had them since the 80’s.
Harbeth and classic Spendor, can be listened to for hours on end with no fatigue. They just sound better and better with each session. Is one brand better? Again it really depends on the model. But you can’t go wrong with any of them.
Each combines musicality with just enough detail for my aging ears. Have never heard any brand that moves me more than these two.
The SLH5’s, are close to my SP1, and love them both. Could live with either. I’ll probably sell my SLH5 one day since the 40’s replaced them.
My suggestion would be to narrow down to 2 or 3 and audition before you buy…….
