Spendor SP 100/R2 and Harbeth 40.1 - impressions?

Where I am, it's difficult to audition these two flagship speakers side-by-side or at home, so opinions/impressions from anyone would be most welcome.

Feedback on other forums is that the Harbeth may be marginally the "better'' speaker, but I'm not convinced.

Matching amps would likely be from MBL.

Thanks in advance
