Kazio,
Nice system. The Linn digital gear is great at every price point. And, the ability to do a whole house system in steps is a big advantage.
I also agree that you would be pleasantly surprised at the performance of a good used LP-12. I have a secret I'd like to share with all of you Linn fans. Beg, borrow, buy or steal a tube preamp and give it a try. It made such a huge difference in my system that it's really spooky. Also, the Ridge Street Audio Designs interconnects and speaker cables are perfect with the Linn gear. I find it amazing how many Linn fans there are (although in the audiophool world we are looked down on) because it's so musical.
