I've used all the above (except the Cary) but not all at the same time so I am only guessing that they will go well. I did use the SF Line 2 (and 3) with the W-5 successfully.
I have owned the Studio 60v2, the SF Line 2SE and the Moon W5 all at the same time. All great products whereby you cannot really go wrong except that the Studio 60v2 really do not require the amount of current that the W5 can produce.
My humble suggestion? If you do have a hole burning in your pocket and are looking for an improvement in your music system, perhaps instead of putting that money into a very high quality amp, the money could be siphoned into a different set of speakers. In my experience, this would give you the most improvement/dollar spent at this point.
