Need to choose a good A/V Pre/pro

For 3 yrs I've been using the EAD Theatermaster Signature and have been quite happy with its sonic qualities. As in all electronics it is now becoming obsolete lacking many of the new formats and can't be upgraded. So I am looking for a new A/V processor/preamp. First I was really into buying the ML No.40 and never have any second thoughts. But then I started to feel that its unbelievably high price is just not worth it, because there are some very good ones out there with mostly 1/3 of the No.40's cost.

Now, I am considering the new EAD TM Studio with new TI technology http://shows.soundstagelive.com/shows/avtour2002/ced_showstop4.shtml

then BAT AV-10 http://www.balanced.com/products/line/AV10wp.html

and maybe the BelCanto PRePro http://www.belcantodesign.com/index2.html

These all should cost somewhere between 10-15K and all should be very good equipment eventhough none is shipping at the moment.

What do you think I should do? Whichone of them will have the most advantages?

Thanks
