From what I’ve heard of either I’d say they’re quite different. The Totems were quite agile and dynamic, but the Harbeths seemed better balanced.
I also found the Totems a bit sharp up top too, but this was about 10 years ago, the Forests I think, tall and quite slim.
As for the Harbeths, the M30s were said to have the best treble as they shared the same tweeter as the M40s. You should check to see if this still remains the case.
If you’re sensitive to treble issues, you’re quite right to be careful. For some of us, they’re a real deal breaker.
