Joe,
Glad you're okay with the Teres bits. :)
If you can get a Shelter 901 for $1100 from a safe source, I'd jump on it. Tell the wife she can have the house and the silver. You get the stereo and the records. ;)
I haven't heard a Koetsu Black, but nobody has ever put it above a 901 in any area except the midrange. The 901 can be a tiny bit thin there. I'm sure a Black is warmer/fuller in the mids.
I'll rave about my 901 if you like, tell you how astounding it is for both big classical and big rock, that you have no idea until you've heard one. But I wouldn't want to influence your decision. ;)
