Well, it intrigued me enough to go to the ARC website. I can't tell, unfortunately, if the VT200 MkI has the input stage of the VT200 MkII and the VT100 MkIII. The use of the J-FET and 6H30 input tubes in the input stage is the major improvement I've heard in the more recent ARC designs; if those are in the VT200 MkI, then I'd think it would be the better amp. If not, unless you really need the extra 3db of power (and with an 8 ohm load, I'm not sure about that), you might want to consider upgrading your VT100 to MkIII status to take advantage of the new input stage (I hate these constant upgrades, but this one may be worth it).
