Well Tempered/CROFT/Harbeth...London SG or NAGAOKA

This system has performed very nicely with my Charisma Denon 103.... However, I don't want to keep borrowing my Step Up and 0.5 meter Interconnect from my main system. So I'm leaning toward a HO/MM to simplify and get this setup up and running on it's own. The synergy between the London and CROFT phono is well documented... And as many know, they like damped arms, so the SG should perform well with the Amadeus. The London SG retails at around $1,200 US. Enter Nagaoka... I believe the NEW Well Tempered MM is actually a modified Nagaoka, but based on it's price, it may haven begun life as a 150 or 200.  I'd likely go a bit higher up the line to a 300 or 500 series. The London seems like the way to go, but I do have concerns about the whole no Cantilever thing. I guess these are not for the faint of heart, as they say. Then of course, I don't want to sell the Nagaoka short. I like what I've heard about these, and they seem to fall in to the more full bodied, and not Hi-Fi or exaggerated camp. The London, I'm not so sure as they say these are so alive and open sounding. That may not be a bad thing, as long as they are not crude or etched in any way. Thanks in advance!
