Amplifier Choices for Harbeth HL-P3 ES2

Looking for recommendations on creating the perfect system around these speakers. Associated equipment are an Audible Illusions L1, and a Jolida jd100a with mullards. Love the current sound with my Linn Katans but moving on to Harbeth for less fatigue.
the sonic signiture of the linn is not quite as refined as the harbeth, but its so close that it begs me to ask what kind of front end you are using. fatigue isn't something that is usually associated with any linn loudspeaker. in fact, the harbeth is a livelier variation of a classic bbc ls3/5 design. both speakers are much more musical in a nearfield enviroment.
