Hi, Thanks for your reply.
I eventually decided to keep my A45 power amp and will trade in my Linn MDSI and EAR864 preamp for a Linn Akurate DSM. It has also a very good phono stage. I heard the 2 pieces together and they sounded beautiful with a pair of B&W 804. My speakers have less efficiency: 88db vs 90 of the B&W but go much deeper. Several Linn experts and multi brand dealers believe is the preamp I should fix. In the future I might bi-amp with an additional Acccuphase or change the power amp to Naim, let's see. But I don't fancy much the sound of an all Linn system, the power amp make it too dry and lean eventually, even if bi-amped and Aktiv.
