Is the Harbeth HL-P3 ESR model much better than the HL-P3 ES, folks? I used to have the latter and it was one of the least memorable small speakers I have owned and sold them for £350 or so, and in mint condition. Ran them with a gamut of amps from fancy valves to powerful hybrids and many solid state, but they never really changed their rather grey character.
I don't have much experience of BBC designs but I heard the Falcons at a show run by a modest Primare integrated i15 amp and almost bought them on the spot!
