Again great advice from Lugnut IMO. I agree that Aktiv is the way to go eventually, and I agree preamp first. When I listened to various combinations of Linn components, active and passive, that really stood out. The active setup let me hear all too well if the preamplification was ordinary. I ended up deciding that before going active I'd get a Kairn. (Although I ended up not getting the Linn system, I still remember the sound... ).
One nice thing about a Linn active system is that you don't have to use Linn amplification. An external box ( Tunebox, yes ? Thanks Lugnut. ) will hold the cards.
OK now Joolz, thanks for asking about sources. I like Naim players a lot and you might well find one of them fit very well between Genki and Ikemi. I would listen for depth, timbres, presence and purity, as the Genki has drive down pretty well and you'll get even more of this as you upgrade to active. There are lots of other players too, though, and if you haven't started listening to them yet, you have fun fun fun ahead!
