Help for preamp and phono stage. Tube options

Hi,
I know I am replying quite late to this post.. I eventually chose an EAR684 and the matching with the accuphase A45 sounds good, at least to my ears.
The cables I am using are Wireworld Eclipse thru the amps, and the speakers are connected with Linn cables K400, if I am not mistaken with the code.
SInce I live in Japan, I have the chance to get good prices on local products. And since I am about to leave the country early May I was wondering if getting one more Accuphase to bi-amp. I don't know if my only A45 is enough to drive the Majik Isobarik. I was thinking to add an A30, A45 or P4100.
Any advice? Do I need more power than one A45?
Thank you so much.

I was speaking with a Linn dealer yesterday. He has had the line in the past and is picking it up again. I have enjoyed the line as it's very musical. I asked him about set up and associated components and he said that in his opinion, he feels that using an all Linn system is best. Keep in mind that he also sells Ayre and Mac gear too among others. He said most of his customers just keep it simple as they love the Linn sound.

I remember hearing Linn last year at another dealer and he had the speakers triamped I believe. It may even have been an active system. I don't know Linn that well other than hearing it at my local dealers who carry it. It was highly musical and even dynamic when bi or tri amped. I don't know which. Have you heard it in a bi amped mode?

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.
