Linn Unidisc SC

I'm interested in users opinions on Linn Unidisc SC performance, Red Book and SACD, especially when used with it's preamp section directly into power amp, and not just as a transport. I'm currently using Sony DVP NS999ES, Modified Bitstream DAC, McIntosh C-45 preamp., Theta Digital Dreadnaught II and VonSchweikert VR-4JR, and was thinking about replacing Sony AND McIntosh with Linn Unidisc SC. The only thing that worries me is digital processing section of Linn in the same chassis as preamp and possible interference of digital circuits with preamp section. Appreciate your time in advance.
