mx135 vs. C45 mcintosh

Looking to complete my home theater system with OPPO 205 and Krell amp.
Need an analog 5.1 channel preamp
My choices are mcintosh c45 and mx135
2 channel audio is also very important to me. I intend to go analog from OPPO into macintosh preamp. Using all the processing from oppo.

1. which of these is a better for both home theater and 2 channel stereo, as well as 5.1 sacd ?
2. I know mx135 can do all this, not sure if C45 can. Not clear if it's a 2 channel or multichannel preamp.
If it can, would be as good as mx? for HT? for 2ch?
3. Which is a better value and less likely to break over time? I'm assuming it's a more completed device..

prices for c45 is 2,500 and mx135 2000 (mx seems better value, original msrp 7k)

thoughts?
