IMHO It appears that both Dev and Samuel may be measuring their expected value calculations from the point of view regarding the bias of their cost of purchasing the Ref 5. If the lower actual relative buying opportunities for the new user/purchaser of the ARC preamplifier is wildly variable between these two gentlemen, it could have the possibility of accentuating the potential cost/benefit perceptions of the potential gains of the Ref 5 over the Ref 3. If that price is marketly different, the purchasing entry point along or within the marketing channel could and would most likely affect that bias of measuring utility.
