I would defer to 9rw's direct experience. However, just to give you some other feedback, I've heard several ARC fans who think the D240 is the best SS amp ever made by ARC.
I don't have experience with the 100.2, but I did listen to a D240MkII recently and was very impressed. Other SS amps may present a higher fidelity in certain areas, but I think the D240 excels in mimicking a tube sound from a SS design. This is difficult to do and can explain why some ARC fans, who are normally tube fanatics, like it.
Perhaps this is the source of the confusion in your situation. If you have the 100.2 and asked for an amp with a more "tube-like" sound as your message says, I can see a dealer recommending the D240. I wouldn't castigate your dealer just yet, unless he won't let you take the D240 home and see for yourself whether the deal is worth it.
