@cd318 I take your point about Rega speakers, I bought an all Rega system (P3, Elex-R, DAC-R) so needed a speaker tuned to BBC monitor profile to work with them (Harbeth, Spendor, ATC) and opted for the Spendor A4 because it is a small-ish room.
This review (yes I know What HiFi is viewed with distaste by many A'goners) makes clear the benefit of staying with matched components: the Rega Isis and Osiris both have weaknesses but they cancel each other out and sound good together:
