The latest MF indeed makes a beautiful little stack of silver and blue. I listened to the Arcam and MF back to back and the MF was a little more refined sounding. I remember thinking the music sounded more whole and less disected. I listened to the exact same combos and really wanted it a flash new system but, in the end, I put together a mix of used and new. I really enjoyed listening to the CDMNT1's. Every chance I got I went and listened to them. They are by far the best of the series. I decided I wanted floorstanders and the NT8's or 9's just didn't do it for me. They fell flat in many ways. I felt the NT1 sounded better than most of the other B&W's of any line they had. But, that's just me.
If you like that sound... and you can find a dealer for Revel... try to take a listen to the Revel M20. It's not as polite as the B&W but, it's definitely got a similar liveliness and imaging quality as the NT1... and better bass.
IC's are an interesting thing... and what you have sound like good stuff but, it's sort of a hodge podge. I would consider going with one type of material and a similar aged cable. With IC A, B, and then speaker cable C, it'll be tough to know how to improve your cables.
I haven't found a lot better than Kimber PBJ or KC-1 for under $200. (I have found a few, that are slightly better though) The silver lace sounds good from everything I've read but, haven't heard them in person. I guy named Nathan on this board has them... maybe worth asking him about it.
When I was talking about the 4TC and 8TC... I meant that they are good but, somewhat tricky to match in a system.
Good luck with your very nice system!
